The purpose of this document is to present a potential design to the client to build an acetic acid (CH3COOH) plant in the United Kingdom. The plant will have the capacity to produce 400,000 tonnes per annum of acetic acid base product from a feedstock of methanol and carbon monoxide. As an overview, the methanol carbonylation process is highly efficient in that it produces acetic acid with more sought after selectivity and purity.
Environmental Impact Assessment has been proven successful in outlining the main environmental issues in relation to this project. The general location considerations linked to the potential pollution produced (odours, noise, traffic) has been analysed, justifying the measures that will be put in place to minimize them. The handling of raw materials and the final product both on and off site has been studied in depth in order to outline the features and add-ups that can be applied to reduce the impact on the environment.
In addition to environmental methodologies, principles of process control and instrumentation have been applied throughout the design stage of this project with the aim of creating a process that is ultimately safe, that complies with all the necessary safety regulations, efficient, that will not suffer unnecessary downtime to avoidable failures and maintenance being carried out on key piece of process equipment and not suffer performance impairments due to poor design, as well as being economically stable, linked to the plants efficiency, an efficient plant will bring a certain amount of economic stability in addition to ensuring unnecessary equipment or instrumentation is not put in place.
Economic evaluation of this project indicates viability, the return of investment is 53% and the net profit of £1,378,000,000 is very lucrative figure for a 20-year investment. The project payback time of 2 years demonstrates that this project is highly feasible and has the potential to attract numerous investors.

There are some tasks that given by our university that we have done here.
Bangladesh is the 4th largest producer of Rice in the world with an approximate yearly production of 50+ million MT. The majority of the final product is par-boiled rice, the process involves steaming. Annual Rice Husk production is about 10 million tonnes in Bangladesh. Thus Bangladesh produces a huge amount of rice husk ash and more than 80% of it finds no use and needs disposal. Such disposals are causing major Environmental hazards for the Country. Every MT of Rice Paddy produces about 40Kg of RHA thus causing total production of around 2M MT of RHA every year in Bangladesh. It is a unique opportunity for Bangladesh to use agricultural waste to produce Sodium Silicate instead of burning sand with costly natural gas. Save nature and go for Green.
Rural population is not having the access to LPG gas stoves.
Rural population can’t afford costly LPG gas stove.
Costs are increasing rapidly as subsidies are going down.
Availability of large biomass is making the wood stoves as the readymade option for rural India.
Increased use of these stoves, increasing the overall emissions including particulate matter in the atmosphere and because they are burning with very low efficiency are ending up with burning much more renewable fuel
Rice Husk Ash (RHA), a waste product of the rice industry is rich in silica. A simple method based on alkaline extraction, followed by acid precipitation was developed to produce pure silica xerogels from RHA, with minimal mineral contaminants.
Emerging Technologies and Biological Systems for Biogas UpgradingKleberTorresSemprebo
Emerging Technologies and Biological Systems for Biogas Upgrading systematically summarizes the fundamental principles and the state-of-the-art of biogas cleaning and upgrading technologies, with special emphasis on biological processes for carbon dioxide (CO2), hydrogen sulfide (H2S), siloxane, and hydrocarbon removal. After analyzing the global scenario of biogas production, upgrading and utilization, this book discusses the integration of methanation processes to power-to-gas systems for methane (CH4) production and physiochemical upgrading technologies, such as chemical absorption, water scrubbing, pressure swing adsorption and the use of membranes. It then explores more recent and sustainable upgrading technologies, such as photosynthetic processes using algae, hydrogen-mediated microbial techniques, electrochemical, bioelectrochemical, and cryogenic approaches. H2S removal with biofilters is also covered, as well as removal of siloxanes through polymerization, peroxidation, biological degradation and gas-liquid absorption. The authors also thoroughly consider issues of mass transfer limitation in biomethanation from waste gas, biogas upgrading and life cycle assessment of upgrading technologies, techno-economic aspects, challenges for upscaling, and future trends.
Providing specific information on biogas upgrading technology, and focusing on the most recent developments, Emerging Technologies and Biological Systems for Biogas Upgrading is a unique resource for researchers, engineers, and graduate students in the field of biogas production and utilization, including waste-to-energy and power-to-gas. It is also useful for entrepreneurs, consultants, and decision-makers in governmental agencies in the fields of sustainable energy, environmental protection, greenhouse gas emissions and climate change, and strategic planning.
The foodservice industry has been accused of wastefulness but the issues of food packaging and packaging waste are not straightforward and there is no easy answer or solution to the problem. The Footprint Forum discusses the issues and the ways that the supply chain can work together on best practice guidelines.

A difusão consiste na condução da cana em aparelhos conhecidos como difusores, a fim de que a sacarose adsorvida ao material fibroso seja diluída e removida por lixiviação ou lavagem num processo de contra-corrente. Visando reduzir a quantidade de água necessária, é feita uma operação de retorno do caldo diluído extraído. Assim, ao final da operação, quando o bagaço se apresenta exaurido ao máximo, faz-se a lavagem com água fresca. O líquido obtido dessa lavagem, contendo alguma sacarose que se conseguiu extrair do bagaço, é usado na lavagem anterior por ser um pouco mais rico e, assim sucessivamente. Esse retorno pode ser efetuado de cinco a 20 vezes, dependendo do grau de esgotamento desejado.
Com a utilização de difusores obtém-se eficiência de extração da ordem de 98%, contra os 96% conseguidos com a extração por moendas. Os tipos de difusores utilizados são:
difusores oblíquos (DDS);
difusores horizontais;
difusores circulares.
No Brasil é usado o difusor horizontal. A seguir, estão relacionadas algumas vantagens do uso de difusores:
baixo custo de manutenção;
baixo consumo de energia;
obtenção de caldos mais puros;
alta extração de sacarose;
menor desgaste.
A desvantagem do uso de difusores é que estes carregam mais impurezas com o bagaço para as caldeiras, exigindo maior limpeza das mesmas devido à pior qualidade do bagaço.
A moagem é um processo de extração do caldo que consiste em fazer a cana passar entre dois rolos, com uma pressão pré-estabelecida aplicada a eles. A moenda deve extrair o caldo, como também produzir bagaço, no final do processo, com um grau de umidade que permita sua utilização como combustível nas caldeiras.

Bioheat, Biopower and Biogas - Developments and Implications for AgricultureKleberTorresSemprebo
This report complements earlier OECD work on liquid biofuels and provides information on biomass based heat and power, as well as on biogas. It discusses the heterogeneous portfolio of different biomass feedstocks, conversion technologies, and pathways of utilisation. It also shows that governments in many countries provide substantial support to the production and use of renewable energy in general, and bioenergy in particular; these support measures are highly diverse and are given at national and various sub-national levels. The results of a large number of life-cycle analyses of various bioheat and biopower chains reviewed in this study indicate that the objective to reduce GHG emissions and fossil energy use is met; indeed the savings estimated for most chains are substantial when compared to fossil alternatives. At present, most of the chains examined do not compete with food and feed production, and thus the implications for agricultural markets are small. It is clear, however, that if a stronger focus on agricultural biomass crops is to be developed, this will require careful design of support policies so as to avoid compromising the ability of the agricultural sector to provide food and feed in a sustainable manner.
The leading book on the market just got better: With its unique approach covering all aspects of setting up and running a biogas plant, this new edition has been expanded to include recent advances in biomass processing.
The author is a key player in the field, who has designed numerous small- and industrial-scale biogas plants, and who is also a long-time lecturer on biogas production, thus combining didactical skill with real-life expertise. As such, he covers both the biological and technical aspects of biogas generation. The full range of biogas substrates and processing modes is explained, from agricultural and industrial waste to marine algae and sediment. On-site use of biogas for conversion into electricity, fuel and heat is also discussed, as are safety and regulatory issues. Many real-life examples of European biogas plants already in operation illustrate the contents, as do numerous schemes, diagrams and summary tables.
For this new edition, biogas analytics and quality control required for feeding biogas into natural gas networks are included, as is a completely new chapter on the microbiology of biogas-producing bacterial communities.
NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.
