7、This article gives an account of ways of mending and preventing erosion of methanol equipment main rectifying tower.
1、A patent technology about rectifying tower tray was introduced.
5、The aspect of transform contains; reactor, rectifying tower, heat exchanger and compressor etc.
10、In addition, the invention reduces the separation difficulty, reduces the size of the rectifying tower and further reduces the equipment investment.
6、The utility model relates to a pressure reducing rectifying apparatus for trichloroethylene, composed of a heating system, a rectifying tower, a cooler and a receiving container, etc.
3、The system mainly comprises a rectifying tower (1), a water washing tower (13), a coarse distillation tower (26), a methanol tower (35) and an impurity tower (42).
2、The system comprises a low pressure rectifying tower, a pressurizing rectifying tower, a tower kettle reboiler, an overhead condenser and an auxiliary condenser;
4、In this paper, a method of optimizing reflux ratio in rectifying tower is introduced. An economical model of the rectifying tower and its solving approaches are also presented.
9、The process design is completed for the key equipment of heat exchanger for the process streams of inlet and outlet, DME rectifying tower and methanol distillation tower.
8、The existing problems in bottom tower control of butadiene rectifying tower in certain plant are investigated. The inference control strategy based on soft measurement is stated.
