Research and Development in the area of Chemical Engineering is focused on development of process and technologies for production, separation, purification and recovery of materials required in the nuclear fuel cycle.

The key features underlying the development effort are self reliance, very high purity specifications, very low separation factors, high recoveries, optimal utilization of scarce resources, environmental benignity, high energy efficiency, stable continuous operation and automation. CFD modeling, process simulation, development of novel contactors, highly specific extractants, catalysts and membranes are being increasingly developed for process intensification. Non power application of nuclear energy has been demonstrated in the area of water desalination using the Multi-Stage-Flash (MSF) technique. Membrane technology has been deployed for desalination and in nuclear waste treatment.

Recent developments include: Hydrodynamic studies of Liquid Phase Catalytic Exchange (LPCE) system; Development of fluidized bed technology for applications in nuclear fuel cycle; Synthesis and Evaluation of Novel Extractants; Development & Testing of Compact Electrolyzer Plant for Large Scale Hydrogen Generation. Under Advanced Technologies and applications, R&D for TBM materials has been initiated; Molecular modeling of hybrid calix-crown ligand for cesium metal ion extraction is in progress and Microchannelled contactors are being explored for various applications in the field of chemical engineering to exploit their unique process-intensifying features. Under R&D on Cryogenics, design and development work on turbo expander and other related equipment is in progress. Refrigeration load test was conducted on the indigenously developed 20K helium refrigerator and a helium liquefier has been commissioned.
