浅谈小硫磺回收装置(“三同时”设施)的安全管理及生产技术

Discussion on Safety Management and Production Technology of Small Sulfur Recovery Device (“Three Simultaneous” Facilities)

摘要: 从2015年1月1日开始施行的《环境保护法》第41条规定：建设项目中防治污染的设施，应当与主体工程同时设计、同时施工、同时投产使用，即“三同时”。中国石油庆阳石化分公司(以下简称庆阳石化公司)硫磺回收联合装置(包括一套60 t/h的污水汽提、一套50 t/h的溶剂再生、一套3000吨/年)单套小规模联合装置(“三同时”设施，以下简称联合装置)，2010年8月26日建成中交，2010年10月18日联合装置同新厂装置同时投产。联合装置于2015年利用大检修时间进行硫磺回收尾气升级达标治理改造。联合(含兄弟单位硫磺回收)装置存在的安全生产实际案例及“三同时”运用、管理经验：几年来针对生产装置生产运行存在的事故隐患，通过连续不间断的进行排查解决，对安全生产实际案例的处置演练，提高员工的预防和应急处理能力。崇尚科学技术，大力促进四新技术的应用，实现了单套联合装置安全长周期运行，尾气排放均值达到 ≤ 220 mg/m³ GB 31570-2015石油炼制工业污染物排放标准(≤400 mg/m³)。

Abstract: Article 41st of the Environmental Protection Act, which has been in force since January 1, 2015, provides that: “Facilities for the prevention and control of pollution in construction projects shall be designed at the same time as the main project, constructed at the same time, and put into pro-duction at the same China Petroleum Qingyang Petrochemical Branch (hereinafter referred to as Qingyang Petrochemical Company) sulfur recovery joint device (including a set of 60 t/h sewage vapor, a set of 50 t/h solvent regeneration, a set of 3000 tons/year) single set of small-scale joint units (“three simultaneous” facilities (hereinafter referred to as joint units), August 26, 2010 com-pleted in China, October 18, 2010 Joint installation and new plant equipment at the same time put into operation. In 2015, the combined unit used large overhaul time for sulfur recovery tail gas up-grading and improvement. Practical cases of safe production and “three simultaneous” application and management experience of combined (including brotherly unit sulfur recovery) units: in the past few years, according to the hidden trouble existing in the production and operation of the production plant, it has been solved through continuous and uninterrupted investigation and in-vestigation, to handle the actual cases of safety production, improve the staff’s ability of prevention and emergency handling, advocating science and technology, promoting the application of four new technologies, realizing the safe long period operation of a single set of combined devices, and the average emission of tail gas reaches ≤220 mg/m³ GB 31570-2015 Emission Standard of Pollutant from Petroleum Refining Industry (≤400 mg/m³).
