基于历年常减压停工出现的问题:蒸汽压力不足、相关装置停工争抢蒸汽现象严重、操作员劳动强度大。大港石化于2011年成功实施了装置换热流程进行化学清洗。解决了停工期间换热设备吹扫难度大,耗费大量蒸汽仍吹扫不干净,同时操作人员消耗体力大等突出问题。 Based on the problems of atmospheric depressurization and downtime in previous years, the steam pressure is not enough and the relevant facilities stop competing for steam, resulting in serious operator labor intensity. Dagang Petrochemical in 2011 successfully implemented the device heat exchange process for chemical cleaning. Solve the shutdown during the heat exchanger equipment difficult to purge, consume a lot of steam is still purging is not clean, while the physical strength of the operator and other outstanding problems.
