炼油厂生产是连续的系统化流程作业。其生产装置停工大检修的显著特点是:同时停工的生产装置套数多,检修工作量大,检修工期短、工作量与工期的矛盾大;设备和管线中的介质易燃易爆,且一部分装置在停工检修,另一部分装置还要继续生产,相互的公用工程系统连在一起,生产与检修同时进行,检修安全管理难度非常大。 Refinery production is a continuous, systematic process operation. Significant features of its production equipment downtime major overhaul: the same time the number of production facilities shut down, maintenance workload, short maintenance period, the workload and duration of the conflict; equipment and pipeline flammable medium, and part of the device In the downtime overhaul, the other part of the device but also continue to produce, mutual public utility system together, production and overhaul at the same time, overhaul safety management is very difficult.
