【技术实现步骤摘要】
一种酸性气制硫铵系统
本技术涉及一种酸性气制硫铵系统,涉及酸性气处理技术。
技术介绍
炼厂气主要来源于原油蒸馏、催化裂化、热裂化、石油焦化、加氢裂化、催化重整、加氢精制等过程。炼厂气中往往含有酸性气体杂质,这些酸性气体杂质的主要成分是H2S气体和CO2气体,会造成大气污染和设备的腐蚀。随着原油的劣质化、重质化加剧,炼厂气中的H2S气体含量逐年上升。选择性脱除H2S可以降低能耗,减少吸收剂使用量,降低生产成本,为企业带来一定的效益。酸性气体的存在会增加对管道和设备的腐蚀而影响其使用寿命。氨法烟气脱硫是基于碱性脱硫剂与酸性SO2之间的化学反应。FGD过程包括两个基本的化学反应过程:吸收:SO2吸收生成为亚硫酸盐;氧化:亚硫酸盐氧化为硫酸盐。
