Chemingineering – A Novel Batch Reactor
– K Sahasranaman, Independent Consultant
Batch reactors play a crucial role in the chemical industry, which however has remained the same over the years. It is considered as a workhorse, which mixes various ingredients to create a new product with beneficial properties. In the article our columnist explains how a disruptive development has emerged in a novel batch reactor which offers significant improvements in heat transfer.

How Pilot Plant Can Optimize the Reactors
– Rajeev Hallur, Vasant Jagtap-Patil, Nitin Birajdar, Xytel India Pvt Ltd
Reactor is the heart of a chemical process. Productivity depends very much on the operations of a reactor. Therefore optimizing a reactor is very important. This article explains with a few case studies how pilot plants help in optimizing.

Catalysts – Chemical Process Plants’ Backbone 
– S. Raghava Chari, Industry Consultant
Rigorous operating parameters of a reaction such as pressure, temperature, etc can be
significantly reduced by the use of catalysts. Catalysts also make many reactions possible – which otherwise are difficult. Both capex and opex get reduced through the use of catalysts – which therefore have become ubiquitous in the chemical industry. There are several other advantages too. A refresher on catalysts.
