Summary:•Proposed a HiGee that differs fundamentally from present-day HiGees.•Akin to spinning disk technology.•Separated two-phase flow prevails against the interpenetrated flow in other HiGees.•For simple and heat-integrated absorption and distillation systems. We proposed a HiGee fundamentally different from the present-day HiGees. A separated two-phase flow prevails in the proposed HiGee in contrast to an interpenetrated flow in other HiGees. It comprises of a rotating disc placed in the middle of two stationary discs which are enclosed in a casing. The liquid flows as a thin film on both sides of the rotating disc. The gas, fed into the casing of the unit, is in a converging spiral flow, counter current to the liquid flow, through the two narrow channels formed between the rotating disc and stationary discs. We validated the efficacy of the proposed HiGee.
