The Application Of Leybold Vacuum Unit In PTA
PTA is the basic raw material of polyester fiber. Its technological process is complicated and the technical content is high. In the past, the development of domestic PTA production line was relatively lagging. In the later period, the Leybold vacuum unit was used in the raw material PTA, which reduced the cost of the PTA production line and accelerated my country’s industrial modernization.
In PTA, Leybold vacuum units are mainly used for vacuum filtration, evaporation, drying, exhaust gas treatment and other systems. The principle is to use the physical properties of different substances to be affected by air pressure to different degrees. Under a certain vacuum environment, the Certain components are separated, and the heat of reaction of the system can also be reduced by the expansion of the gas. As the vacuum pump material used in PTA is the best choice of duplex stainless steel, the high-demand material increases the difficulty of pump manufacturing. With the continuous development of China’s industry in recent years, Leybold vacuum units have begun to replace other equipment. Operation is good.
The application of Leybold vacuum units to the PTA production line can not only reduce the investment cost of the PTA production line, but the strong after-sales service lineup also brings convenience to the maintenance and repair of the PTA production line.
The application of Leybold vacuum unit in PTA
It is mainly used for the vacuum filter system in the refining stage of the PTA production line. Its stability and reliability will directly affect the quality of the PTA product, and the selection of the Leybold vacuum unit should be based on the working conditions of each PTA production line and the unit process The pipeline loss that needs to be considered, make the correct gas volume correction.
