摘要：
针对某炼化公司在加工绥中36-1原油时换热器压降增大、换热效率降低的问题，采用元素组成、红外光谱和甲苯溶剂溶解试验等多种手段对堵塞物进行分析，结合油田采油工艺过程及添加的采油助剂，确定加工绥中36-1原油时换热器堵塞物是由聚丙烯酰胺在换热器表面形成笼状结构引起的。针对分析结果，提出将常压塔塔顶油打入原油泵的在线解决换热器堵塞的清洗方案，实际应用结果表明该方案有效可行，具有降本增效和节能环保的双重效果。

Abstract:
The problem of high pressure drop and low heat exchange efficiency of heater exchanger when processing Suizhong 36-1 oil is analyzed by element composition, FT-IR, and toluene dissolution test. Combined with the knowledge of crude oil production process and the additives used, the material with cage-like structures caused by polyacrylamide is found to be the reason for heater exchanger blockage. An online clean method, in which the No.1 side cut of atmosphere distillation tower is pumped into the inlet pipeline of crude, is proposed. The commercial application proves that the suggested method is effective and feasible, and has both cost efficiency and energy saving effect.
Key words: heat exchanger, blockage, polyacrylamide, Suizhong 36-1 crude, oline cleaning
