国产真空过滤机在PTA装置中的应用

Application of vaccum filter made in China to PTA plant

介绍了该厂PTA装置精制单元应用国产真空过滤机,改造原有的常压离心机后的生产状况。通过技术应用、工艺改造前后运行对比,对此项分离技术在PTA装置高负荷生产上应用的实际效果进行了总结。该技术的应用,保证了PTA单元安、稳、长、优、高负荷运行,经济效益显著,产品品质得到有效控制,为PTA装置高负荷生产创造了良好的条件。

The application of vaccum filter made in China to refining unit in PTA plant, the production conditions after modifying the ori.＇ginal normal pressure centrifuge were introduced. By the comparison of technology application, running conditions pre-and post-process modification, the application practice results of this separation technology to PTA plant high load production were summarized. The safety, steady, long and optimum high load running is guaranteed ,the economy benefit is obvious, the product quality is effectively controlled. This technology provides better conditions for the high load production of PTA plant.
