为贯彻落实天然气净化装置低成本高质量发展要求,延长装置检修周期,降低设备设施故障和腐蚀发生率,开展了天然气净化装置长周期运行分析并提出对策措施,对确保稳步实现净化装置长周期平稳运行目标具有重要的现实意义。针对川渝两地天然气净化装置长周期运行现状、关键因素、管理保障措施等进行深入分析,提出天然气净化装置运行应重点关注依法合规、原料气气质、供水供电、两剂(催化剂和溶剂)质量、系统水质控制、仪表系统稳定、腐蚀预防等关键因素,可从设计、制造、施工、运行、维护、管理、操作等方面进行天然气净化装置的适应性改造与优化提升,同时充分应用四新技术(新技术、新工艺、新材料、新设备)、信息化技术,建立配套完善的管理措施和长效机制,全面提升人员素质能力,为推进天然气净化装置长周期运行提供借鉴。

In order to implement the requirements of low cost and high quality development of natural gas purification plant, it is proposed to extend the period between maintenance cycle of the plant(long cycle operation) and reduce the incidence of equipment and facility failure and corrosion rate. This paper analyzes the long-cycle operation of natural gas purification plant and proposes countermeasures to ensure the steady realisation of the significant goal of stable operation of the purification plant in the long-cycle operation mode. This paper presents an in-depth analysis on the current situation, key factors and management safeguards for the long-cycle operation of natural gas purification plants in Sichuan and Chongqing. The paper proposes that the operation of natural gas purification plants should focus on seven key factors, including legal compliance, feed gas quality, water and power supply, quality of catalyst and solvent, system water quality control, robust instrumentation system, and corrosion protection. Adaptive upgrading and optimization can be performed from design, manufacturing, construction, operation, maintenance, management, operation, etc., while fully applying the four new technologies(new techniques, new process, new materials, new equipments) and information technology to establish a complete set of management measures and achieve sustainable long term efficient and safe operation, enhance the overall quality and capability of personnel, so as to provide reference for promoting the long-cycle operation of natural gas purification facilities.
