Abstract: This paper proposes a new separation technology for process gases,which liquefies carbon dioxide and separates it from process gases through cooling by means of the liquefaction characteristics of carbon dioxide at low temperature.The process gas after removing carbon dioxide by liquefication is further purified,which is better to match with Rectisol unit.This process can help to reduce the facility size,investment cost and operation cost of Rectisol,which has obvious advantages over the existing Rectisol process.
