Connecting Science and Technology for a brighter tomorrow

Established in 1973, the chemical engineering group provides a broad spectrum of engineering inputs to the other research and development groups at CSIR-NEIST. The group has expertise in coupled research of Applied and Basic research for generation of knowledge base, knowhow and knowwhy. The group is involved in industry oriented research in the area of Separation and Purification Technology, Reaction Calorimetry, Food & Nutraceuticals and Reaction Engineering & Catalysis. Membrane Technology is one of the priority research area of the group. Transport phenomena in solid/liquid membrane based separation, catalytic membrane reactors, controlled transport in microcapsule membrane of stimuli responsive smart polymeric micro gel, facilitated transport in gas and liquid phases through host-guest chemistry are the basic/applied R&D work of the group. Membrane based Technology for Biomolecule separation from natural feedstock, Racemic Resolution, Gas separation etc. are the priority research work for Translational research from the group. Engineering analysis of chemical reaction systems i.e. reaction-diffusion phenomena in heterogeneous catalysed reactions, Design and Scale up studies of bioprocesses, Reaction calorimetry, development of process for food & nutraceuticals etc. are also the current activities of the group.
