Conversion of BATCH PROCESSES TO CONTINUOUS PROCESSES OR SEMI BATCH PROCESSES:- Censci is having expertise in nitration, sulfonation, chlorination etc.
Processes at threshold level:- Chemical reaction is depend on several factors such as concentration of reagents, temperature, etc. Censci is helping to carry out the reaction at the threshold level so as the energy control can be better maintained thus by reducing the time of reaction and energy cost.
