摘要
分析了某催化裂化干气、液化气脱硫装置存在胺液老化发泡、液化气脱硫塔筛孔堵塞、液化气带胺和再生塔处理能力不足问题的原因。进行了技术改造,液化气脱硫塔塔盘的结构形式为降液管式,更换胺液再生塔塔盘为高效立体塔盘,并增设反冲洗胺液过滤器,更换新配制胺液。改造装置运行平稳,处理能力提高,净化干气、净化液化气中H2S的质量分数均小于2×10-6,贫胺液中H2S的质量浓度为0.5g/L,产品质量合格。
Causes for aging and frothing of FCC dry gas and liquefied gas desulfurization equipment by amine liquid, liquefied gas desulfurization tower sieve pore blockade, liquefied gas mingling with amine, recycle tower treatment lack are analyzed. After the innovation, quality fraction of H2S is less than 2×10-6, quality concentration of H2S in the poor amine solution is 0.5 g/L. The product is proved to be qualified.
