根据《国家安全监管总局关于加强化工过程安全管理的指导意见》（安监总管三〔2013〕88号），第（五）条，对涉及重点监管危险化学品、重点监管危险化工工艺和危险化学品重大危险源（以下统称“两重点一重大”）的生产储存装置进行风险辨识分析，要采用危险与可操作性分析（HAZOP）技术，一般每3年进行一次。

近日，公司顺利完成国内在役30万方/天液化天然气（LNG）装置HAZOP分析，历经3天，完成涉及原料气压缩系统、脱碳系统、脱水系统、脱重烃系统、液化系统、制冷系统、LNG储罐系统、LNG装车系统、BOG回收系统、燃料系统、导热油系统、仪表风及氮气系统、循环水系统及消防系统等系统的HAZOP分析，促进业主全面查找和及时消除在役LNG装置的安全隐患，提高LNG装置本质安全化水平。

According to the Guiding Opinions of the State Administration of Safety Supervision on Strengthening the Safety Management of chemical Processes (Safety Supervision Chief III (2013) No. 88), article (5), risk identification and analysis of production and storage devices involving key supervision of hazardous chemicals, key supervision of hazardous chemical processes and major hazards of hazardous chemicals (hereinafter collectively referred to as "two key and one major") are carried out. The Hazard and Operability Analysis (HAZOP) technique is typically performed every three years.

Recently, the company successfully completed the HAZOP analysis of the 300,000 square meters/day liquefied natural gas (LNG) plant in service in China, after 3 days, Complete HAZOP analysis involving raw gas compression system, decarbonization system, dehydration system, heavy hydrocarbon removal system, liquefaction system, refrigeration system, LNG storage tank system, LNG loading system, BOG recovery system, fuel system, thermal oil system, instrument wind and nitrogen system, circulating water system and fire protection system, etc. Promote owners to comprehensively find and timely eliminate the safety hazards of in-service LNG installations, and improve the level of intrinsic safety of LNG installations.
