泄漏检测与修复技术在乙苯-苯乙烯装置的应用研究

采用泄漏检测与修复(LDAR)技术对乙苯-苯乙烯装置开展了全面检测和统计分析,发现泄漏密封点并通过维修减少挥发性有机物(VOCs)排放。结果表明:乙苯-苯乙烯装置密封点泄漏率为1.30%,修复成功率为60.0%;修复后VOCs排放量为1.8370t/a,减排率为52.0%。该乙苯-苯乙烯装置容易泄漏的密封点类型为法兰、阀门和连接件,占泄漏排放量的93.1%。通过实施LDAR技术,为企业减少了VOCs排放,减少油品损失,同时改善了周边环境质量。

80 kt/a Unit for Manufacture of Ethylbenzene/Styrene from FCC Dry Gas at Hainan Refining ＆ Chemical Company Came on Stream

The first industry chain at SINOPEC Hainan Refining and Chemical Company, Ltd. （HRCCL）-the 80 kt/a unit for manufacture of ethylbenzene/styrene-has been started up successfully at the first attempt to deliver qualified products, which have symbolized the extension of the petrochemical industry chain at Hainan＇s Yangpu Economic Development Zone. In order to effectively utilize the FCC dry gas resources of the refinery, HRCCL and Jiangsu Jiasheng Company have jointly funded to construct a 80 kt/a unit for manufacture of ethylbenzene/styrene from FCC dry gas. The ethylbenzene unit has adopted the technology licensed by CAS Dalian Institute of Chemical Physics and Luoyang Petrochemical Engineering Company, while the styrene unit is equipped with the technology jointly developed by the Shanghai Petrochemical Research Institute and other institutions.
