目前辽河、胜利原油的加工量迅速增加,据一九八四年统计,加工辽河原油的炼油厂有:锦州、锦西、鞍山、广州、盘锦、辽化、镇海等七个厂;加工胜利原油的炼油厂有:胜利、茂名、南京、济南、广州、镇海、武汉、安庆、九江、上海、青岛、长岭等十二个厂。在管输原油的含盐量、含硫量明显升高及辽河原油的酸值有所增加的情况下,高温重油部位的环烷酸及高温硫的腐蚀,已成为炼油工业中一个急待解决的问题。辽河原油是一种含硫低,含盐低,酸值高,有严重腐蚀的原油。管输辽河原油的酸值一般都在0.5mgKOH/g以上,有时甚至高达1.0mgKOH/g。原油酸值越高,环烷酸的含量也越高,在高温重油部位的腐蚀性也越强。在
Currently Liaohe, Victory crude oil processing volume increased rapidly, according to statistics in 1984, processing Liaohe crude oil refineries are: Jinzhou, Jinxi, Anshan, Guangzhou, Panjin, Liaoyang, Zhenhai seven plants; processing of crude oil The refinery are: victory, Maoming, Nanjing, Jinan, Guangzhou, Zhenhai, Wuhan, Anqing, Jiujiang, Shanghai, Qingdao, Changling and other 12 plants. Under the circumstances that the salinity of pipeline transportation crude oil, the sulfur content increase obviously and the acid value of Liaohe crude oil increase, the corrosion of naphthenic acid and high temperature sulfur in the high temperature heavy oil part has become an urgent problem in the oil refining industry The problem. Liaohe crude oil is a low sulfur content, low salt, high acid value, serious corrosion of crude oil. Pipeline Liaohe crude oil acid value are generally above 0.5mgKOH / g, and sometimes even up to 1.0mgKOH / g. The higher the crude oil acid value, the higher the naphthenic acid content, the more corrosive the high temperature heavy oil site. in
