丁湘华等：液体硫化氢处理剂室内评价技术研究
摘要：为解决H,S处理剂在适用性评价过程中检测标准及技术指标不规范、产品名称混乱、检测方法及装置不统一、与实际生产需要有差距等问题，采用自主设计的硫化氢处理装置和吸收器，对新疆油图现用8种H,S处理剂的脱殖效果和硫容进行室内评价，并通过检测管法及碘量法检测H,S含量进行对比实验。实验结果表明：采用检测管法，其可溶性疏化物去除率≥95.1%、残余疏化氢质量浓度≤5.7mg/m、殖容≥37.3mg/L；采用碘量法，其可溶性硫化物去除率≥ 95.5%、残余硫化氢质量浓度≤5.1mg/m"、疏容37.5mg/L；新疆油图现用H,S处理剂基本上可以满足油田生产需要，其可溶性殖化物去除率均大于90%，有两种H,S处理剂经评价残余硫化氢
质量浓度不满足≤5mg/m的要求，不同处理剂硫容差别较大，关键词：液体HS处理剂；碘量法；检测管法；脱硫效果；硫容 Doi : 10.3969/j.issn.10066896.2017.11.011
Study on the Laboratory Evaluation of the Liquid Treatment Agent for H,S Ding Xianghua, Yang Yang, Peng Jian, Yang Lianyu, Shi Rui, Zhang Guilian
Abstract: In order to solve problems that in the adaptability evaluation process of the treatment agent for H,S, the inspection standards and technical specifications are not standardized, the product name is confused, detection methods and devices are not unified, and there is gap between the actual pro duction needs and the process, the independently designed treatment device and absorber for H,S are used to conduct the laboratory evaluation on the desulfurization effect and sulfur capacity of 8 kinds of treatment agents for H,S that currently used in Xinjiang Oilfield, and the comparison experiment of de tecting content of H,S by the detection tube method and iodometric method is conducted. The experi mental results show that using the detection tube method, the soluble sulfide removal rate is not less than 95.1%, the mass concentration of residual hydrogen sulfide is less than or equal to 5.7 mg/m", and the sulfur capacity is greater than or equal to 37.3 mg/L; using the iodometric method, the removal rate of soluble sulfide is not less than 95.5% , the mass concentration of residual hydrogen sulfide is less thar or equal to 5.1 mg/m', and the sulfur capacity is greater than or equal to 37.5 mg/L: the H,S treatment agents currently used in Xinjiang Oilfield can basicelly meet the needs of oilfield production, and the
soluble sulfide removel rate of each agent is over 90%
There are two kinds of products that cannot
meet the requirement that the mass
concentration
of residual hydrogen sulfide should be less than or
equal to 5 mg/m", and the sulfur capacity of different treatment agents are quite different. Key words: liquid treatment agent for H,S; iodometric method;
detection tube method; desulfur-
ization effect; sulfur capacity
目前，硫化氢（HS）油气藏的开发已成为石油天然气开采的重要组成部分，我国大部分油田都存在HS的污染和危害，不仅对金属设备造成严重的腐蚀破坏，还严重威胁着人们的生命安全"。HS气体的检测方法有很多，主要是国家、行业标准规定
的方法2-4。国家对职业性安全暴露极限及原油中的 HS质量浓度均有明确规定，为保证设备和人员安全、提高原油品质，需要降低原油中的HS含量，甚至脱除H,Si-"。但国内的原油脱除HS技术还不够成熟，而优质的HS处理剂应用是化学脱硫的关
