上海石化总厂化工一厂乙烯装置、芳烃抽提装置分别引自日本三菱、住友公司,技术是比较先进的。在整个生产过程中共使用换热器186台。其中使用海水冷却的有51台。金山地处杭州湾,海水盐份较低,含氧量高,腐蚀性强,为此都应用了牺牲阳极保护,从一九七七年三月开车至今,效果良好。 Shanghai Petrochemical Plant Chemical Plant ethylene plant, aromatics extraction unit were cited from Japan’s Mitsubishi, Sumitomo, the technology is more advanced. In the entire production process using a total of 186 heat exchangers. Among them, there are 51 sets of seawater cooling. Located in Hangzhou Bay, Jinshan has low salt content, high oxygen content and strong corrosiveness. All these have applied sacrificial anode protection. Since its launch in March 1977, Jinshan has achieved good results.
