Limit test of Arsenic
The document presents the limit test procedure for arsenic. It describes how to prepare a solution from the test substance and generate arsine gas by adding potassium iodide and zinc. The gas passes through a piece of mercuric bromide paper, where any arsenic will form a yellow stain. This test stain is compared to a standard stain produced from a solution with a known amount of arsenic. If the test stain matches the standard stain from a 1mL solution, then the substance contains 1 microgram of arsenic per gram. The test is performed at 40°C to achieve a steady evolution of gas over 40 minutes.

The document discusses gas cooler design considerations for CO2 refrigeration systems. It describes how using smaller diameter copper tubes of 5mm allows for more compact gas cooler designs that can withstand higher pressures of up to 130 bar. This reduces the internal volume and refrigerant charge compared to traditional designs. Case studies show how CO2 gas coolers using 5mm tubes can achieve equal or higher capacity compared to R404A designs, using fewer fans and a more compact footprint. The technology allows for more efficient gas cooler designs well-suited for transcritical CO2 refrigeration applications.High pressure vessel leakage in urea plants

Vacuum MEtallurgy: Lecture Vacuum Degassing plant layout and its typesNED University of Engineering and Technology
Vacuum degassing is commonly used in steel production to remove gases like hydrogen and nitrogen from liquid steel. It works by exposing the steel to vacuum conditions, which allows the gases to be readily removed. Specifically, vacuum degassing lowers the levels of dissolved gases to parts per million and improves the quality of the final cast product by preventing cracking defects. It is a critical process that improves both productivity and quality in continuous steel casting.D1 (B2) Jan Suchorzewski - Combined carbonation-frost resistance of sustainab...

The document summarizes research on developing sustainable high-performance concrete with very high slag content for use in wave energy converter hulls. Testing showed that concrete mixes with cement contents as low as 100 kg/m3 and slag replacements over 50% achieved compressive strengths over 100 MPa and frost resistance classified as "very good" even after carbonation. However, one mix (HPC200) showed increased frost scaling after carbonation, requiring further testing. Microscopy revealed microcracking in the carbonated layer for this mix. Overall, the research demonstrates that high-slag concrete can perform well in Nordic climates if evaluated using combined carbonation and frost testing.SaadJutt
The document describes the process for producing primary brine. Rock salt is added to saturators along with water and depleted brine to increase the brine concentration. The brine then flows through settling pits to remove insoluble impurities, and calcium chloride pits to remove sulfate impurities. It then flows through reactors where barium carbonate, caustic soda, and soda ash are added to remove additional sulfate, magnesium, and calcium impurities. The brine is stored in tanks and filtered before being heated in a plate and frame heat exchanger, where the temperature is increased and remaining impurities are reduced.
ORGANIC COATINGS FOR CORROSION PROTECTION OF TRANSFORMERS IN UNDERGROUND CHAM...
Underground electrical transformers are frequently submitted to a very aggressive environment because of the stagnated water of underground chambers which is heated and contaminated. In Brazil, carbon steel structures of underground transformers are usually protected with coal tar epoxy paints in order to ensure their reliability. However, the use of this type of paints is being strongly restricted because coal tar contains complex mixtures of polycyclic aromatic hydrocarbons which contain many toxic and potentially carcinogenic substances. Aiming at replacing coal tar based paints by an environmentally friendly one; several paints were selected in the local market and submitted to performance tests in order to compare them with coal tar based paint. In addition, anodes were evaluated to study the application of galvanic cathodic protection in areas of metal exposure due to coating flaws. This paper presents and discusses the obtained results.

This document summarizes the design of a hydrometallurgical copper processing plant aimed at processing 15 tons of copper oxide ore per day. The plant utilizes a comminution circuit to grind the ore to an optimal size, followed by leaching to extract the copper. Solid-liquid separation then purifies the solution, which undergoes solvent extraction and electrowinning to produce copper cathodes. Laboratory experiments and theoretical calculations were used to design and size the equipment. The plant is estimated to recover over 80% of the copper at a capital cost of $1.5 million and produce around 583 tons of copper annually, making it a viable small-scale option. Recommendations include using design software and specialized engineers to

The Optimization of Carbonitriding Process for 1022 Self-drilling Tapping Scr...International journal of scientific and technical research in engineering (IJSTRE)
A low-carbon steel wire of AISI 1022 is used to easily fabricate into self-drilling tapping screws,
which are widely used for construction works. The majority of carbonitriding activity is performed to improve
the wear resistance without affecting the soft, tough interior of the screws in self-drilling operation. In this
study, Taguchi technique is used to obtain optimum carbonitriding conditions to improve the mechanical
properties of AISI 1022 self-drilling tapping screws. The carbonitriding qualities of self-drilling tapping screws
are affected by various factors, such as quenching temperature, carbonitriding time, atmosphere composition
(carbon potential and ammonia level), tempering temperature and tempering time. The quality characteristics of
carbonitrided tapping screws, such as case hardness and core hardness, are investigated, and so are their
process capabilities. It is experimentally revealed that the factors of carbonitriding time and tempering
temperature are significant for case hardness. The optimum mean case hardness is 649.2HV. For the case
hardness, the optimum process-capability ratio increases by about 200% compared to the original result. The
new carbonitriding parameter settings evidently improve the performance measures over their values at the
original settings. The strength of the carbonitrided AISI 1022 self-drilling tapping screws is effectively improved.PROPOSAL OF 1x30MVA SILICON METAL FURNACE PROJECT

The Optimization of Carbonitriding Process for 1022 Self-drilling Tapping Scr...
The Optimization of Carbonitriding Process for 1022 Self-drilling Tapping Scr...International journal of scientific and technical research in engineering (IJSTRE)
A low-carbon steel wire of AISI 1022 is used to easily fabricate into self-drilling tapping screws,
which are widely used for construction works. The majority of carbonitriding activity is performed to improve
the wear resistance without affecting the soft, tough interior of the screws in self-drilling operation. In this
study, Taguchi technique is used to obtain optimum carbonitriding conditions to improve the mechanical
properties of AISI 1022 self-drilling tapping screws. The carbonitriding qualities of self-drilling tapping screws
are affected by various factors, such as quenching temperature, carbonitriding time, atmosphere composition
(carbon potential and ammonia level), tempering temperature and tempering time. The quality characteristics of
carbonitrided tapping screws, such as case hardness and core hardness, are investigated, and so are their
process capabilities. It is experimentally revealed that the factors of carbonitriding time and tempering
temperature are significant for case hardness. The optimum mean case hardness is 649.2HV. For the case
hardness, the optimum process-capability ratio increases by about 200% compared to the original result. The
new carbonitriding parameter settings evidently improve the performance measures over their values at the
original settings. The strength of the carbonitrided AISI 1022 self-drilling tapping screws is effectively improved.PROPOSAL OF 1x30MVA SILICON METAL FURNACE PROJECT

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.
