摘要
国内炼厂气(干气、液化气)脱硫工艺目前存在若干问题,诸如脱硫工艺没有与主体装置工艺同步发展,MDEA选择性脱硫仍采用传统的低胺浓度,选择性脱硫多采用板式塔,溶液系统粗放型管理及大型新炼油厂脱硫工艺过程过分集中等。针对以上问题提出了相应的对策。
Some deficiencies are existed in domestic refinery gas （dry desulfurization, such as desulfurization technologies have not developed in keeping process development; traditional low concentration amine is still applied in gas and LPG） with the leading MDEA selective desulfurization; plated absorbers are mainly used in selective desulfurization; desulfurizing solution is imperfectly managed; and desulfurization processes are excessively centralized in new large scale refineries, etc.. Aiming at above deficiencies, countermeasures are proposed.
