Industrial Emission Control Catalysts
P.A.E.S. Srinivas, M. Shanmuga Sundaram; Sud Chemie India Pvt Ltd
Various industries use different approaches to reduce pollution. In the bid to reduce pollutants from chemical reactions, many use catalysts to improve the reaction. However, not all catalysts in theory can be used in industries and thus customizing a catalyst for a particular reaction is important. The overall reaction in the end should be able to reduce emissions also. This article gives details about the various catalysts which can
help achieve this objective.

Take a Fresh Look at Your Distillation Columns
Seán Ottewell, Chemical Processing
Improving the performance of distillation can be done by identifying
the end-points in the process, improving the existing equipment and analyzing
the process simulation. Using analytical tools like pinch analysis, column –pinch analysis and digitalization, the process can be stepped up from linear to continual iteration.

Don’t Slip Up with Slipstream Filtration 
Andrew Sloley, Chemical Processing
Hydraulic pressure, size of slipstream, pump flow rates, etc. are among the factors which are used to choose the configuration of slipstream filtration. It is necessary to evaluate all the factors inorder to achieve an optimum configuration of slipstream filtration. If need be, additional pumps also can be installed to increase the output. The author
explains this entire process with examples in the article.

Chemingineering – Unlocking Safety
K Sahasranaman, Independent Consultant
During the lockdown, several plants had to be shut. As the lockdown is lifted chemical plants are being restarted. This has led to quite a few chemical accidents. Restarting of chemical plants has to follow well-laid down step-by-step procedure, as otherwise it can endanger the safety of plant personnel as well as of people in the vicinity. Through this article,our columnist tries to explain how it is necessary to maintain the safety of
equipment and personnel while restarting the plant.
