摘要
Abstract
Industrial application of a combination process of fiber liquid film transfer-lye high efficient regeneration,which was used in the removal of mercaptan from 400 kt/a mixed liquefied petroleum gas(LPG) and FCC LPG,was introduced.It was showed that both the total sulfur contents in the mixed LPG product and the FCC LPG product basically reached 150 mg/m3 and 50 mg/m3 respectively,and more than 97％ of the product was up to standard.The concentration of NaOH in the regenerated lye was about 20％(w).Disulfides as the by-products were recovered,1 t per 3 d.The combination process for LPG from refineries can lead to more stable product quality,higher quality of regenerated lye,lower energy consumption and less emission of soda residue.关键词
