一、防垢剂在炼厂的应用及经济效果工艺设备的原油侧和加工侧结垢使炼油工业耗资很大.例如,换热器结垢使回收热量减少,若维持正常操作,加热炉必须多烧燃料.随着垢物的增多,传热效率不断降低,压降不断增加,最后不得不停工清扫,缩短了开工周期.炼厂结垢比较严重的装置通常是原油蒸馏、催化重整、加氢精制、减粘裂化、焦化、热裂化和催化裂化等.成垢物质的主要来源是:烃类在加热系统高温作用下形成的高分
First, the anti-fouling agent in the refinery applications and economic results Process equipment, crude oil and processing side of the fouling so that the oil refining industry is very large.For example, heat exchanger fouling to reduce heat recovery, if to maintain normal operation, the furnace must Burn more fuel.With the increase of scale, heat transfer efficiency continues to decrease, the pressure drop continues to increase, and finally had to stop working sweeping, shorten the start-up cycle.Silk scale more serious installations are usually crude oil distillation, catalytic reforming, Hydrofinishing, visbreaking, coking, thermal cracking and catalytic cracking, etc. The main sources of fouling substances are the high scores of hydrocarbons formed under the action of the high temperature of the heating system
