运营的原油储罐,在长年累月的使用过程中,造成储罐密封装置不同程度的老化、损坏,导致储罐内部油气挥发,油品损耗,更严重的是,这样的原油储罐在运营过程中风险大大增加,容易引燃油气而造成油品着火、爆炸等重大事故。所以在原油储罐运营的条件下,更换老化、损坏的原油储罐密封装置的技术是十分重要的。有的老罐区由于种种原因,吊车无法进入到原油储罐附近,大大增加了密封材料吊装倒运难度。本文针对以上工程技术难题,经过科学、详细的研究分析,成功的解决了密封装置更换过程中的安全、质量、吊装难题,为以后在运营状态下的原油储罐的密封装置更换起到了指导性的作用。
The operation of crude oil storage tanks has resulted in various degrees of aging and damage of the tank sealing devices during the long-term use of the tank, leading to the volatilization of oil and gas inside the storage tanks and the loss of oil products. More seriously, during the operation of such crude oil storage tanks The risk is greatly increased, easily ignited oil and gas caused by fire, explosion and other major accidents. So it is important to replace the old, damaged crude oil tank seal technology with crude oil tank operations. Because of various reasons, some old tanker areas can not access the crude oil storage tank near the crane, which greatly increases the difficulty of lifting and transporting the sealing material. In view of the above engineering and technical problems, through scientific and detailed research and analysis, the safety, quality and lifting problems in the sealing device replacement process have been successfully solved, which has guided the later operation of the sealing device replacement of crude oil storage tanks Role.
