摘　　要：烯烃装置用于分离裂解产物的油洗塔经常发生严重结焦,以致于生产无法进行。为查明结焦的原因及机理,找出减少烯烃装置结焦的方法,利用裂解色谱、红外光谱及色谱-质谱联用仪等手段对油洗塔的结焦物及流经此塔的物料进行了分析研究。结焦物主要是不饱和芳烃(茚类、苯乙烯类、及环烯烃或二烯烃的复杂的聚合物。垢样中还含有大量沥青质及残碳。In order to find out the cause of coking and plugging in the oil scrubber of the ethylene unit and to reduce the coke deposits, the composition and structure of the coke deposits have been analyzed by PY-CGC and JR. The oils passing through the tower have been determined by CGC-MS. The main components of the coke de posits are unsaturated aromatic compounds(indene, styrene cyclo-di-olefines) and a large amount of residual carbon and pitch.
