在苏联炼油工业中,防止腐蚀的对策主要有三个方面:1.采用耐腐蚀的合金钢,这主要用于加热炉及其它高温条件下;2.工艺—化学方法,即加强原油的脱盐脱水,注碱注氨和加入缓蚀剂,这适用于原油一次加工装置和低温设备;3.钢材表面涂刷涂料,储运、供排水系统和防止环境对设备外表腐蚀可使用这一方法。使用缓蚀剂减少腐蚀程度在苏联炼油工业中展开了广泛的研究和实际应用,并取得了显著的效果。在原油一次加工装置中,苏联采用注氨注碱的方法,以减少腐蚀,但冷换设备
In the Soviet Union’s oil refining industry, there are three main measures to prevent corrosion: 1. The use of corrosion-resistant alloy steel, which is mainly used in furnaces and other high temperature conditions; 2. Process - chemical methods, that is, to strengthen the desalination of crude oil dehydration, Note alkali injection of ammonia and the addition of corrosion inhibitors, which applies to crude oil processing equipment and low temperature equipment; 3. Steel surface coating paint, storage and transportation, water supply and drainage systems and to prevent corrosion of the environment on the equipment can use this method. The use of corrosion inhibitors to reduce the degree of corrosion in the Soviet Union’s refining industry has carried out extensive research and practical application, and achieved remarkable results. In the primary processing unit of crude oil, the Soviet Union adopted the method of injecting ammonia and injecting alkali to reduce corrosion, but cold exchange equipment
