Abstract

Abstract:

The pyrophoric iron sulfides in oil tank was eliminated under THPS(tetrakis(hydroxymethyl)phosphonium sulfate) and ammonium chloride. It was investigated the effect of mass ratio of THPS and ammonium chloride，the concentration and acidity of dissolution agent, temperature， and reaction time on the efficiency of dissolution. The results show that the efficiency of dissolution to iron sulfide is best when mass ratio of THPS and ammonium chloride is 6.5∶0.6,temperature is 80 ℃, pH is 5, reaction time is 8 h, the dissolution of iron sulfide is best. When the concentration of dissolution agent is 14.0%, the efficiency of dissolution to iron sulfide is reach 92.50%.

摘要： 用THPS(四羟甲基硫酸磷)配合氯化铵清除油罐中沉积的硫化亚铁,介绍了THPS在溶解硫化亚铁
方面的实验结果,包括THPS与氯化铵的质量配比,溶解液的浓度和酸度,以及反应温度、反应时间。结果表明,
THPS与氯化铵质量比为6.5∶0.6,温度为80 ℃,pH=5,反应时间为8h时,THPS溶解硫化亚铁的效果最好。溶
解液质量分数为14.0%时,硫化亚铁溶解率可达到92.50%。
