Two processes developed by Wison Engineering have been certified as proprietary technologies by the China Petroleum & Chemical Engineering Survey and Design Association (CCESDA). They are the Falling-film Heat-exchanger with Differential Absorber Technology for an MTO oil absorption tower and a preliminary water treatment technology for bottom quench gasification technology.

The Falling-film Heat-exchanger with Differential Absorber Technology for an MTO oil absorption tower is tailor-made for Wison’s MTO olefin separation process, and also fit for other similar light hydrocarbon separation plants.

It can reduce both the investment cost of the unit and the occupied area of a MTO plant, improve the ethylene recovery rate and decrease energy consumption, thereby markedly improving the light hydrocarbon recovery technical indicators.
