补充资料:裂解气油吸收分离
裂解气分离方法之一,它是利用溶剂油对裂解气中各组分的不同吸收能力,将裂解气中除氢气和甲烷以外的其他烃全部吸收,然后用精馏法将各种烃逐个分离。其实质是吸收精馏过程,作为吸收剂的溶剂油有轻质芳烃、碳四馏分、碳三馏分等。吸收剂的沸点愈高,吸收的平均温度也愈高。与裂解气深冷分离相比,在脱甲烷塔中加入吸收剂可避免该塔采用低温(-100℃或更低),但有关塔釜也因温度的升高使烯烃、炔烃易于聚合而堵塞,并因加入大量吸收剂使能耗增大。所以除个别小型厂外,大型乙烯装置已不再采用此法。
油吸收流程随吸收剂和生产目的不同而不同,以C4馏分作吸收剂的吸收分离流程(见图)为例,裂解气经预分馏除去重质油、压缩(至3.8MPa)除去冷凝的裂解汽油、脱除酸性气体再以活性氧化铝等进行干燥处理后,进入脱甲烷塔中部,C4馏分从塔顶加入,进塔温度均为-25℃。在吸收段中部用蒸发液氨排除一部分因吸收烃类所放出的热量,使吸收的平均温度为-10℃。塔釜用蒸汽加热至67℃以驱出所溶解的甲烷。塔顶蒸出的氢-甲烷馏分回收乙烯后排入燃气管网。脱甲烷塔釜液经冷却到42℃进入乙烯精馏塔,塔压2.3MPa,塔顶温度-20℃。塔顶馏出浓度为95%(摩尔)的产品乙烯;塔釜液在下一塔(分馏塔)内将乙烷-丙烯-丙烷从塔顶分出,并送去裂解。分馏塔压力1.3MPa,塔顶温度为30℃、塔釜为86℃。此塔釜液组成(摩尔)为:丙烯1%、丙烷5%、C4馏分92%、C5馏分2%;冷却后作为吸收剂循环送至脱甲烷塔。由于裂解气中少量C5及更重的烃类残存于吸收剂中,因而抽出部分吸收剂进入再生塔。再生塔釜排出C5及重组分,塔顶蒸出C4馏分与吸收剂混合。
