摘要： This invention is to a process for separating condensed water and entrained solids from an olefin stream so that fouling of the separation equipment by the entrained solids is reduced or eliminated. The process involves injecting an antifouling agent into a water condensing or quench system in an amount to maintain a zeta potential of fouling liquid and a zeta potential of the surface of the quench system both in a positive range or both in a negative range.

摘要翻译： 本发明涉及从烯烃流中分离冷凝水和夹带固体的方法，从而减少或消除夹带的固体污染分离设备。 该方法包括将防污剂注入到水冷凝或骤冷系统中，其量使得维持窒息液体的ζ电位和猝灭系统表面的ζ电位均处于正的范围，或者在负的范围内。
