Through analysis and research on the components of the condensate in the purification gas separators Ⅰ and Ⅱ of the hot potash decarburization unit,it is found that it contains a large amount of oil substances and the components,which are similar to those of low-carbon hydrocarbon liquid products.After optimizing the existing process flow,the condensate containing a large amount of oil substances is three-phase separated to achieve oil-water separation and effective recycling of the condensate in the purification gas separators Ⅰ and Ⅱ of the decarburization unit.It can further improve the recycling efficiency of the condensate,reduce the consumption of desalinated water in the system by about 3×105 m3/a,and increase the oil production by about 11 200 t/a.
