This paper evaluates various methods to reduce sulphur dioxide from coal fired thermal power plant. Flue Gas
Desulphurization (FGD) is a technology which extracts sulphur dioxides from flue gases produced in coal based thermal
power plants, where sulphur content in coal is more than 0.5%.In FGD maximum sulphur dioxide reduction is possible
by controlling of flow of flue gases into the absorber unit by adjusting the blade pitch of axial flow booster fan using a
hydraulic system and varying the concentration of lime stone slurry. In addition, coal blending is one of the solution for
reduction in sulphur content. The results indicate that maximum SO2-reduction is possible with increase in limestone
purity. 100% SO2-reduction may be possible in FGD but at the higher it will cause the design and installation cost of FGD Plant
Flue gas desulfurization is commonly known as FGD and is the technology used for removing sulfur dioxide (SO2) from the exhaust combustion flue gases of power plants that burn coal or oil to produce steam for the turbines that drive their electricity generators.

In 1927, the limestone desulfurization process was first applied in the Barthes and Bansside Power Plants (total
120MW) beside the Thames River in UK to protect high-rise building in London. Up to now, over 10 desulfurization processes have been launched and applied. Based on the desulfurizing agent being used, there include calcium process (limestone/lime), ammonia process, magnesium process, sodium process, alkali alumina process, copper oxide/zinc process, active carbon process, ammonium dihydrogen phosphate process, etc. The calcium process is commercially available and widely used in the world, i.e. more than 90%. Flue gas desulfurization processes, survey made by the coal research institute under the International Energy Agency shows that the wet-process desulfurization accounts for 85% of total installed capacity of flue gas desulfurization units across the world. The wet-process desulfurization is mainly applied in countries, like Japan (98%), USA (92%), Germany (90%), etc. The limestone-gypsum wet desulfurization process, the most mature technology, the most applications, the most reliable operation in the world, may have rate of desulfurization of more than 90%. Currently, the flue gas desulfurization technology used at thermal power plants at home and abroad tends to be higher rate of desulfurization, bigger installed capacity, more advanced technology, lower investment, less land acquisition, lower operation cost, higher level of automation, more excellent reliability, etc. This paper briefs current situations and trends of flue gas desulfurization technology also append short descript of different type of FDG and their category.

Adsorption of hydrogen sulfide using palm shell activated carboneSAT Journals
Abstract Removing H2S from biogas that is produced from anaerobic digestion of palm oil mill effluent is a crucial step in order for the biogas to be utilized as a source of energy. In this study, palm shell activated carbon (PSAC) prepared by steam activation was used to adsorb H2S from simulated biogas. The parameters studied were H2S concentration, adsorption temperature and space velocity. The effect of these parameters towards breakthrough adsorption capacity was studied using statistical analysis with Design Expert Software. H2S concentration and space velocity were found to be significant in affecting the breakthrough adsorption capacity.Adsorption temperature on its own was found not to have significant effect on the breakthrough adsorption capacity but its interaction with other parameters was found to be significant. Characterization of fresh and spent PSAC confirmed and provided further information on the adsorption of sulfur species on PSAC pore surface. Keywords: Activated carbon; Biogas; Hydrogen sulfide; Adsorption

Living in 21st century in itself reminds all of us the necessity of police and its administration. As more and more we are entering into the modern society and culture, the more we require the services of the so called ‘Khaki Worthy’ men i.e., the police personnel. Whether we talk of Indian police or the other nation’s police, they all have the same recognition as they have in India. But as already mentioned, their services and requirements are different after the like 26th November, 2008 incidents, where they without saving their own lives has sacrificed themselves without any hitch and without caring about their respective family members and wards. In other words, they are like our heroes and mentors who can guide us from the darkness of fear, militancy, corruption and other dark sides of life and so on. Now the question arises, if Gandhi would have been alive today, what would have been his reaction/opinion to the police and its functioning? Would he have some thing different in his mind now what he had been in his mind before the partition or would he be going to start some Satyagraha in the form of some improvement in the functioning of the police administration? Really these questions or rather night mares can come to any one’s mind, when there is too much confusion is prevailing in our minds, when there is too much corruption in the society and when the polices working is also in the questioning because of one or the other case throughout the India. It is matter of great concern that we have to thing over our administration and our practical approach because the police personals are also like us, they are part and parcel of our society and among one of us, so why we all are pin pointing towards them.

Globally, Millions of dollars were spent by the organizations for employing skilled Information Technology (IT) professionals. It is costly to replace unskilled employees with IT professionals possessing technical skills and competencies that aid in interconnecting the business processes. The organization’s employment tactics were forced to alter by globalization along with technological innovations as they consistently diminish to remain lean, outsource to concentrate on core competencies along with restructuring/reallocate personnel to gather efficiency. As other jobs, organizations or professions have become reasonably more appropriate in a shifting employment landscape, the above alterations trigger both involuntary as well as voluntary turnover. The employee view on jobs is also afflicted by the COVID-19 pandemic along with the employee-driven labour market. So, having effective strategies is necessary to tackle the withdrawal rate of employees. By associating Emotional Intelligence (EI) along with Talent Management (TM) in the IT industry, the rise in attrition rate was analyzed in this study. Only 303 respondents were collected out of 350 participants to whom questionnaires were distributed. From the employees of IT organizations located in Bangalore (India), the data were congregated. A simple random sampling methodology was employed to congregate data as of the respondents. Generating the hypothesis along with testing is eventuated.

By implementing talent management strategy, organizations would have the option to retain their skilled professionals while additionally working on their overall performance. It is the course of appropriately utilizing the ideal individuals, setting them up for future top positions, exploring and dealing with their performance, and holding them back from leaving the organization. It is employee performance that determines the success of every organization. The firm quickly obtains an upper hand over its rivals in the event that its employees having particular skills that cannot be duplicated by the competitors. Thus, firms are centred on creating successful talent management practices and processes to deal with the unique human resources. Firms are additionally endeavouring to keep their top/key staff since on the off chance that they leave; the whole store of information leaves the firm's hands. The study's objective was to determine the impact of talent management on organizational performance among the selected IT organizations in Chennai. The study recommends that talent management limitedly affects performance. On the off chance that this talent is appropriately management and implemented properly, organizations might benefit as much as possible from their maintained assets to support development and productivity, both monetarily and non-monetarily.
A STUDY OF VARIOUS TYPES OF LOANS OF SELECTED PUBLIC AND PRIVATE SECTOR BANKS...IAEME Publication
Banking regulations act of India, 1949 defines banking as “acceptance of deposits for the purpose of lending or investment from the public, repayment on demand or otherwise and withdrawable through cheques, drafts order or otherwise”, the major participants of the Indian financial system are commercial banks, the financial institution encompassing term lending institutions. Investments institutions, specialized financial institution and the state level development banks, non banking financial companies (NBFC) and other market intermediaries such has the stock brokers and money lenders are among the oldest of the certain variants of NBFC and the oldest market participants. The asset quality of banks is one of the most important indicators of their financial health. The Indian banking sector has been facing severe problems of increasing Non- Performing Assets (NPAs). The NPAs growth directly and indirectly affects the quality of assets and profitability of banks. It also shows the efficiency of banks credit risk management and the recovery effectiveness. NPA do not generate any income, whereas, the bank is required to make provisions for such as assets that why is a double edge weapon. This paper outlines the concept of quality of bank loans of different types like Housing, Agriculture and MSME loans in state Haryana of selected public and private sector banks. This study is highlighting problems associated with the role of commercial bank in financing Small and Medium Scale Enterprises (SME). The overall objective of the research was to assess the effect of the financing provisions existing for the setting up and operations of MSMEs in the country and to generate recommendations for more robust financing mechanisms for successful operation of the MSMEs, in turn understanding the impact of MSME loans on financial institutions due to NPA. There are many research conducted on the topic of Non- Performing Assets (NPA) Management, concerning particular bank, comparative study of public and private banks etc. In this paper the researcher is considering the aggregate data of selected public sector and private sector banks and attempts to compare the NPA of Housing, Agriculture and MSME loans in state Haryana of public and private sector banks. The tools used in the study are average and Anova test and variance. The findings reveal that NPA is common problem for both public and private sector banks and is associated with all types of loans either that is housing loans, agriculture loans and loans to SMES. NPAs of both public and private sector banks show the increasing trend. In 2010-11 GNPA of public and private sector were at same level it was 2% but after 2010-11 it increased in many fold and at present there is GNPA in some more than 15%.

This Researcher looked into how hard Nylon-6/BaSO4 composites are and how well they wear. Experiments were done based on Taguchi design L9. Nylon-6/BaSO4 composites can be tested for their hardness number using a Rockwell hardness testing apparatus. On Nylon/BaSO4, the wear behavior was measured by a wear monitor, pinon-disc friction by varying reinforcement, sliding speed, and sliding distance, and the microstructure of the crack surfaces was observed by SEM. This study provides significant contributions to ultimate strength by increasing BaSO4 content up to 16% in the composites, and sliding speed contributes 72.45% to the wear rate
ROLE OF SOCIAL ENTREPRENEURSHIP IN RURAL DEVELOPMENT OF INDIA - PROBLEMS AND ...IAEME Publication
The majority of the population in India lives in villages. The village is the back bone of the country. Village or rural industries play an important role in the national economy, particularly in the rural development. Developing the rural economy is one of the key indicators towards a country’s success. Whether it be the need to look after the welfare of the farmers or invest in rural infrastructure, Governments have to ensure that rural development isn’t compromised. The economic development of our country largely depends on the progress of rural areas and the standard of living of rural masses. Village or rural industries play an important role in the national economy, particularly in the rural development. Rural entrepreneurship is based on stimulating local entrepreneurial talent and the subsequent growth of indigenous enterprises. It recognizes opportunity in the rural areas and accelerates a unique blend of resources either inside or outside of agriculture. Rural entrepreneurship brings an economic value to the rural sector by creating new methods of production, new markets, new products and generate employment opportunities thereby ensuring continuous rural development. Social Entrepreneurship has the direct and primary objective of serving the society along with the earning profits. So, social entrepreneurship is different from the economic entrepreneurship as its basic objective is not to earn profits but for providing innovative solutions to meet the society needs which are not taken care by majority of the entrepreneurs as they are in the business for profit making as a sole objective. So, the Social Entrepreneurs have the huge growth potential particularly in the developing countries like India where we have huge societal disparities in terms of the financial positions of the population. Still 22 percent of the Indian population is below the poverty line and also there is disparity among the rural & urban population in terms of families living under BPL. 25.7 percent of the rural population & 13.7 percent of the urban population is under BPL which clearly shows the disparity of the poor people in the rural and urban areas. The need to develop social entrepreneurship in agriculture is dictated by a large number of social problems. Such problems include low living standards, unemployment, and social tension. The reasons that led to the emergence of the practice of social entrepreneurship are the above factors. The research problem lays upon disclosing the importance of role of social entrepreneurship in rural development of India. The paper the tendencies of social entrepreneurship in India, to present successful examples of such business for providing recommendations how to improve situation in rural areas in terms of social entrepreneurship development. Indian government has made some steps towards development of social enterprises, social entrepreneurship, and social in- novation, but a lot remains to be improved.
OPTIMAL RECONFIGURATION OF POWER DISTRIBUTION RADIAL NETWORK USING HYBRID MET...IAEME Publication
Distribution system is a critical link between the electric power distributor and the consumers. Most of the distribution networks commonly used by the electric utility is the radial distribution network. However in this type of network, it has technical issues such as enormous power losses which affect the quality of the supply. Nowadays, the introduction of Distributed Generation (DG) units in the system help improve and support the voltage profile of the network as well as the performance of the system components through power loss mitigation. In this study network reconfiguration was done using two meta-heuristic algorithms Particle Swarm Optimization and Gravitational Search Algorithm (PSO-GSA) to enhance power quality and voltage profile in the system when simultaneously applied with the DG units. Backward/Forward Sweep Method was used in the load flow analysis and simulated using the MATLAB program. Five cases were considered in the Reconfiguration based on the contribution of DG units. The proposed method was tested using IEEE 33 bus system. Based on the results, there was a voltage profile improvement in the system from 0.9038 p.u. to 0.9594 p.u.. The integration of DG in the network also reduced power losses from 210.98 kW to 69.3963 kW. Simulated results are drawn to show the performance of each case.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Low sulphur coal blended with coal of inferior quality parameters gives a mixture, which could emit according
to standards. The change to low sulphur coal might need some modifications in power plants.
Boiler modernisation is another possibility of emission reduction. When the boiler’s life cycle concludes, it
might be more efficient to repair it than to replace it with a new one.
Technology change is the radical method of emissions reduction in a coal fired power station. The main
alternative for the power sector is natural gas. It has lots of advantages—emission reduction, better effectiveness, it could
be built in a shorter time than a coal fired power station, and it needs less investment costs.
Flue Gas Desulphurization (FGD) is a technology which extracts sulphur dioxides from flue gases produced in
coal based thermal power plants, where sulphur content in coal is more than 0.5%. The coal produced from Indian mines
contains only 0.4% sulphur contents, so in India this technology was not required much. But, now a lot of companies are
importing coal from other countries like Indonesia, South Africa which contains sulphur contents ranging from 0.6-0.9%.
So it is made mandatory to install the FGD plant to maintain the ambient air quality standards.
2. FGD PLANT CHEMISTRY
Flue gas desulphurization is a process to extract sulphur contents from flue gases, where there is a chemical
reaction that takes place inside the absorber tank, between limestone slurry, sulphur dioxide, water & oxygen given to
system and gypsum is produced inside.
Sulphur dioxide is extracted from flue gases in wet scrubber, slurry of alkaline sorbent limestone react with the
sulphur dioxide [3].The limestone powder used is approximately 85% pure and more than 90% of the limestone particles
have to pass through a 325 mesh screen. This is necessary in order to have the maximum amount of limestone particles
that can possibly contact the sulphur dioxide molecules in the gas stream. For chemical reaction purpose the limestone
powder is mixed with 15-30% slurry introduced into the FGD vessel, re-circulated, and sprayed into the gas stream.
Fig.1: Absorber reaction tank [7]
2.1 ABSORBER TANK REACTION
Flue gases (containing SO2) entered in the absorber (Fig. 1) come in contact with limestone slurry (CaCO3). The
reaction takes place in wet scrubbing process producing CaSO3 (calcium sulphate) and can be expressed as :
CaCO3 (solid) + SO2 (gas) → CaSO3 (solid) + CO2 (gas) (1)
When wet scrubbing with Ca(OH)2 (lime slurry), the reaction also produces CaSO3(calcium sulphite) and can be
expressed as [4] :
Ca(OH)2 (solid) + SO2 (gas) → CaSO3 (solid)+ H2O (liquid) (2)

208
To partially offset the cost of the FGD installation, the CaSO3 (calcium sulphite) is further oxidized to produce
marketable CaSO4·2H2O (gypsum) using oxidation blowers. This technique is also known as forced oxidation :
CaSO3 (solid) + H2O (liquid) + ½O2 (gas) → CaSO4.2H2O (3)
CaSO4. 2H2O is called gypsum and has market value [5].
2.2 FLUE GAS DESULPHURISATION PROCESS
FGD is a process to extract sulphur dioxide from flue gases and to produce gypsum. The process is a
combination of different systems. Main components of FGD Plant are:
1. Flue Gas System
2. Limestone Handling System
3. Process Water System
4. Absorber System
5. Gypsum Handling System
6. Utility Water System
7. DDCMIS
3. METHODOLOGY USED
Following methodologies are used to reduce sulphur dioxide from the flue gases, which reduces the atmospheric
pollution.
1. Control of flow of flue gases into the absorber unit by adjusting the blade pitch of axial flow booster fan using a
hydraulic system.
2. Variation in concentration of lime stone slurry.
3. Blending of coal at various proportions. The different ratio of high and low calorific value coals are fed to the
the boiler.
4. EXPERIMENTAL SET UP
Flue gases entered through inlet damper, and the flow is boosted using an axial flow booster fan. The high flow
flue gases (Fig.2) entered in absorber tank and come out through the outlet damper to chimney. Both inlet and outlet
dampers are hydraulically operated and provided with common hydraulic system consists electrically operated hydraulic
pumps, accumulators, necessary instruments and valves etc. Hydraulic system is operated by the main Distributed
Control System (DCS) as part of FGD operation.
Continuous Emission Monitoring System (CEMS) is provided in Inlet and Outlet flue gas duct of scrubber unit
to monitor the SO2 (Sulphur Dioxide) level of flue gas during FGD operation. By outlet SO2 monitor, the percentage of
scrubbing (SO2 removal) is calculated with reference to inlet SO2 monitor. Both inlet and out let SO2 level will be
displayed in the FGD control room.

Flue gas desulphurisation module is provided with independent axial type booster fan (Fig.3). The booster fan is
used to control the flow of flue gases into the absorber tank. The blade pitch of the booster fan can be adjusted by means
of hydraulic pumps [7].
Fig.3: Axial Booster Fan [7]
The hydraulic actuator system (Fig.4) comprises the following main elements:
1. An actuating cylinder moving axially along the fan axis and turning with the rotor.
2. A piston within the actuating cylinder which is axially fixed and rotates with the same speed as the cylinder
3. A feedback rod
4. A stationary control valve which receives the command to change the blade angle via an actuating gear unit
outside of the fan housing and converts it into a hydraulic signal.
Pressurized oil will be directed to the appropriate cylinder side, imparting an axial movement to the cylinder.
This axial displacement causes the impeller blade to turn.

5. RESULTS AND DISCUSSION
5.1 SULPHUR REDUCTION BY MEANS OF BLENDING OF COAL
Fig.5: Sulphur content Vs coal blend ratio
Coal imported from South Africa and Indonesia having higher calorific value. It may be noted that the HCV coal
contains maximum amount of sulphur content nearly 0.9%. To reduce sulphur content in coal the low calorific value coal
is blended with HCV coal. Fig.5 shows the ratio of coal blending then reduction in sulphur content.
5.2 COAL CONSUMPTION AT DIFFERENT RATIO OF BLENDING
Fig.6 shows the coal consumption for different blend. If HCV coal is used the coal flow rate is decreased. In
case of HCV coal is blended with LCV coal then coal consumption is increased. Thus depending on type of coal and ratio
of blending coal handling plant needs to be designed.
Fig.6: Coal consumption at various ratio of blending
5.3 SO2 REMOVAL THROUGH FGD IN 100% HCV COAL CONSUMPTION
Fig.7 shows the variation of SO2 removal rate as a function of blade pitch. When high sulphur content coal is
used (100% HCV) the coal consumption rate is 230 tons per hour. The SO2 removal rate varies from 175.95 kg/h to 3519
kg/h. with respect to proportions of flue gases supplied through FGD plant. In 30% booster fan blade pitch opening the
SO2 removal rate is 1056 kg/h. The SO2 removal efficiency is 25.50%. The 85% of efficiency is achieved when
maximum flow is possible.

Fig.7: SO2 removal at 100% HCV coal
5.4 SO2 REMOVAL THROUGH FGD AT VARIOUS PROPORTIONS OF COAL BLENDING
Fig.8: SO2 removal rate in FGD at different proportions of coal blend
A variety of low and high sulphur coals from various sources can be blended in different proportions to meet
normal and optimal limits for SO2 emissions. As sulphur contents are directly proportional in blending. The blend ratio of
component coals can be determined based on sulphur content to meet emission levels. Fig.8 shows the SO2 removal rate
at different proportions of coal blending. From the figure, it is clear that increasing the blade pitch proportionately
increases SO2 reduction across all blends. In LCV coal sulphur removal rate is less because LCV coal contains only 0.1%
of sulphur. The installation of FGD is not required in power plants when used with low calorific value coal.
5.5 SO2 REDUCTION EFFICIENCY WITH CONCENTRATION OF LIMESTONE PURITY
The available limestone consists of 80-95% of reactive calcium. The SO2 removal efficiency is increased with
increase in lime stone purity (Fig.9). In case of 30% of blade pitch opening the SO2 removal efficiency is 24% with 80%
of lime stone purity. The efficiency is increased upto 25.5% and 27% in increase of limestone purity 85% and 90%
respectively.

6. CONCLUSIONS
The use of high calorific value coal reduces the fuel consumption per unit power but increase in sulphur dioxide
production rate. Fuel blending is one of the best method to reduce sulphur content. Amount of sulphur dioxide is also
reduced by supplying the flue gases through flue gas desulphurisation plant. Maximum efficiency can be obtained by
passing maximum amount of flue gases through FGD but in turn depends on design of FGD plant. With increase in
purity of limestone the sulphur dioxide removal rate can be increased.
