一、概 述 本厂有四台以油为原料的造气炉。这四台炉子气化所用原油、重油、油炭浆等原料,分别由三个贮油罐供给。由于油品杂、含水量高且波动较大,直接影响气化炉的工艺条件及安全生产,给操作带来很多困难。因此,按照贮油罐操作规模,每班要排水2次(当烧含水油时,排水达4次),以降低原料油中的含水量,便之达到气化工艺条件要求。在排水过程中,因为没有有效的技术控制手段,仅靠肉眼观察和手动活门控制,又由于观察点与控制活门相距较远,常常在排
First, an overview The factory has four oil as raw material gas stove. The four furnace gasification of crude oil, heavy oil, coal slurry and other raw materials, respectively, by the three oil storage tank supply. Due to miscellaneous oil, high water content and large fluctuations, a direct impact on gasifier process conditions and safety, to the operation of a lot of difficulties. Therefore, in accordance with the scale of the operation of the storage tank, each class should be drained 2 times (when the water-containing oil, the drainage of up to 4 times), in order to reduce the moisture content of the feedstock oil, it reached the gasification process conditions. In the drainage process, because there is no effective means of technical control, visual inspection alone and manual valve control, but also because the observation point and the control valve is far apart, often in the row
