摘要

杀菌剂是海洋油气开采行业防治微生物腐蚀(Microbiologically influenced corrosion, MIC)的常用方法。然而,杀菌剂可能导致微生物腐蚀行为发生改变,同时石油的存在也会对杀菌剂的使用效果造成一定的影响。 通过细胞计数、腐蚀失重、表面分析和电化学分析等方法,研究了石油存在下杀菌剂四羟甲基硫酸磷(Tetrakis(hydroxymethyl)phosphonium sulfate, THPS)对硫酸盐还原菌Desulfobaculum bizertense(简称D. bizertensis)腐蚀行为的影响。 结果表明,THPS 虽然可以抑制D. bizertensis 的生长,但会加剧D. bizertensis 对X70 管线钢的腐蚀。 同时石油的加入,使腐蚀电位进一步升高,表明即便添加了杀菌剂,石油仍会促进D. bizertensis 对X70 的腐蚀。 该结果为海洋含油环境中杀菌剂的合理使用提供了参考。

Abstract

Bactericides are a common method for preventing and controlling microbiologically influenced corrosion (MIC) in the offshore oil and gas extraction industry.However,bactericides may cause changes in the behavior of microbial corrosion,and the presence of petroleum will also have a certain impact on the effectiveness of bactericides.In this work, the effect of tetrakis (hydroxymethyl) phosphonium sulfate(THPS) on the corrosion behavior of biocide sulfate-reducing bacteria (Desulfobaculum bizertense) in the presence of petroleum was studied by cell counting, corrosion weight loss, surface analysis and electrochemical analysis.Results showed that although THPS could inhibit the growth of D.bizertensis,it aggravated the corrosion of D.bizertensis on X70 pipeline steel.Meantime,the addition of petroleum further increased the corrosion potential, indicating that even with the addition of bactericides, petroleum still promoted the corrosion of D. bizertensis on X70.The above result provided a reference for the rational use of bactericides in marine oily environments.
