Next Generation Mass Exchanger
Ratnesh Tiwari, Serguei Dessiatoun, Amir Shooshtari, Michael Ohadi
Through his PhD research, blended with his industrial expertise, Ratnesh aims to demonstrate the next generation mass exchanger to be used for several leading industrial processes such as CO2 capture, NH3 absorption. His current research focus is to apply micro-channel technology to refrigeration and oil and gas industrial processes by means of process intensification that would lead to miniaturization of heat and mass exchanger equipment in the current industrial processes.

Self-Cleaning Microchannel Reactor
Self-Cleaning Microchannel Reactor
Stefan Bangerth, Serguei Dessiatoun, Amir Shooshtari, Michael Ohadi
Micro structure surfaces are known for their potential to enhance absorption processes, e.g. in absorption refrigeration or gas cleaning applications. One of the main hurdles to more widespread usage of the technology is its sensitivity to clogging and fouling. The S2TS laboratory aims to address this obstacle by implementing an innovative self-cleaning mechanism into the reactor. Additionally, the reactor’s high stability design will allow to gather data on absorption using microchannels under elevated pressure conditions.
