前言在加工含硫原油时,必须采取抑制 HCl 和H_2S 腐蚀的措施。HCl 和 H_2S 腐蚀主要发生在常压塔顶系统(包括冷凝冷却器)。腐蚀的危害不仅直接破坏金属设备和造成停工检修时人力物力的浪费,而更主要的是造成停工期间产值的巨大损失。因此,国外对防腐工作都很重视,每年都要投入大量的人力物力来研究和解决这方面的问题。目前,在国外广泛采用的常压塔防腐措施是:原油深度脱盐、原油注碱、常压塔顶
Preface In the processing of sulfur-containing crude oil, measures must be taken to suppress the corrosion of HCl and H 2 S. HCl and H 2 S corrosion mainly occur in atmospheric overhead systems (including condensing coolers). The damage caused by corrosion not only directly damages the metal equipment and causes the waste of manpower and material resources during stoppage inspection, but more importantly, it causes huge loss of output value during the stoppage of work. Therefore, foreign countries attach great importance to anti-corrosion work, and every year they devote a great deal of manpower and resources to studying and resolving the problems in this respect. At present, atmospheric pressure tower anti-corrosion measures widely used in foreign countries are: deep desalination of crude oil, crude oil injection of alkali, atmospheric pressure tower
