- 摘要:
- 中国的石油对外依存度高达60.6%,原油加工数量和原油品种多样化,给石油化工行业的装置带来了严重的腐蚀冲击。为了挖掘石油化工行业中防腐蚀存在的问题并提出相应的对策,以“腐蚀控制工程生命周期”全过程链条上的目标为主线,以石油化工行业35家央企的腐蚀调查报告数据和相关资料数据为依据,通过分析得出石油化工行业在防腐蚀领域的技术和管理方面存在的问题,提出提高设计、开发新技术和运用新材料,加强从业人员培训，加强监造、检测、监测、维护及工程施工质量的管理，严格执行标准规范,建立健全数据库、档案、评价体系、决策系统等建议,并以“腐蚀控制工程生命周期”标准为主线,实行有效的PDCA循环,达到全面的防腐蚀管理,形成螺旋式攀升来提升防腐蚀成效,达到降低石油化工行业腐蚀成本的目的。研究可为石油化工行业提供技术和管理方面的改进借鉴,在指导企业依据“腐蚀控制工程生命周期”标准,全面提高防腐蚀成效方面具有重要意义。
China’s dependence on imported oil is as high as 60.6%. The increase in crude oil processing volume and the diversification of crude oil varieties have brought serious corrosion impact on the facilities in petrochemical industry. This paper aims to find out the existing issues of corrosion protection in petrochemical industry and put forward the corresponding countermeasures. With the goal of “life cycle corrosion engineering and control” as the main theme, based on the corrosion survey data and relevant data of 35 state-owned enterprises in the petrochemical industry, we analyzed the existing problems in the field of corrosion management and control in the petrochemical industry. Then we proposed countermeasures including design improvement, new technology development and new material application, enhance staff training, strengthen the manufacturing supervision, testing, monitoring, maintenance and engineering construction quality, strict implementation of the standards and specifications; and establish a sound database, filing and evaluation system and decision-making system. On top of that, we implemented effective PDCA cycle with the standard of “full life cycle of corrosion engineering and control”as the main theme to achieve complete corrosion management in terms of prevention and control. A spiral climbing effect is achieved in upgrading the performance of corrosion control and lowering the capital cost of petrochemical industry. The study can provide reference for the improvement of technology and management in petrochemical industry, and is of great significance in guiding enterprises to improve the effectiveness of corrosion management in accordance with the “life cycle corrosion engineering and control” standard.
