【摘要】 腐蚀是石油化工设备最常见的失效形式，加注中和剂是重要的工艺防腐手段之一。目前，中和剂多为有机胺或其混合物，现有中和剂评选技术措施单一，无法综合各种因素的影响。结合层次分析与模糊综合评价，优化出一种中和剂评选方法。以常减压装置防腐为例，确定了中和剂评价筛选指标体系的两级层次结构模型。通过20碳钢腐蚀挂片、中和滴定等实验，获得了乙二胺、三乙胺、吗啉、 N,N-二甲基乙醇胺和3-甲氧基丙胺这5种单组份有机胺中和剂的指标数据。确定中和剂从优到劣的综合性能排序：乙二胺、 N,N-二甲基乙醇胺、三乙胺、 3-甲氧基丙胺和吗啉。研究结果可为石油化工、天然气储运工程等行业提供一套科学有效的中和剂评选技术，并为中和剂的开发和复配改进提供理论依据。更多还原

【Abstract】 Corrosion is the most common forms of failure in petrochemical equipment, and injecting neutralizing agents is one of the important process anti-corrosion measures to prevent corrosion.At present,most neutralizing agents are organic amines or their mixtures, and the existing technical measures for selecting neutralizing agents are single, which can’t comprehensively consider the influence of various factors.A neutralizer selection method was optimized by combining the analytic hierarchy process(AHP) and fuzzy comprehensive evaluation. By focusing on the anti-corrosion performance of an atmospheric and vacuum distilation unit,a two-level hierarchical structure model for the neutralizer evaluation and screening index system was determined. The index data of five single-component organic amine neutralizers, namely ethylenediamine,triethylamine, morpholine, N, N-dimethylethanolamine, and 3-methoxypropylamine, were obtained through experiments such as corrosion coupon and neutralization titration on 20 carbon steel. The comprehensive performance of neutralizers in descending order was as follows: ethylenediamine,N, Ndimethylethanolamine, triethylamine, 3-methoxypropylamine, and morpholine. The research results can provide a scientific and effective selection technology for neutralizers in industries such as petrochemicals and natural gas storage and transportation engineering and provide a theoretical basis for the development and improvement of neutralizers.更多还原
