Process Development / Design Experience

The process development / design experience includes leading process development / design teams on the following sponsored projects :
  1. Hexachlorocyclopentadiene  - This project involved bench scale work as well as designing and setting up of a pilot plant which included three different types of chemical reactors. Throughout the process development work, mathematical modeling was used extensively for data analysis, which resulted in a very efficient use of the experimental effort put into the project.
  2. Benzaldehyde  -  This project involved laboratory scale catalyst development in microreactors without gas recycle, and designing and setting up a single tube pilot plant involving gas recycle. The use of mathematical modeling in the design of the pilot plant enabled the project team to achieve the expected results from the pilot plant just after a few runs.
  3. Monochlorobenzene  -  This project involved preparation of the basic process engineering package for a commercial MCB plant of 60 T/day capacity, and interaction with the client during implementation of the project.
