The PTA production base built in Dalian Changxing Island has an annual capacity of 11.6 million tons, which is one of the PTA production bases with a larger capacity in the world at present, and has strong industry competitiveness in the domestic market. With the continuous development of the petrochemical industry, the demand for large compressors and drying equipment is also increasing. The SFA-4200CNE compression heat drying machine introduced by Hengli Dalian Petrochemical adopts high-end energy-saving devices, and uses waste heat for effective energy conversion in the process of heating, regeneration and cooling, in order to achieve the purpose of two-way energy saving of heating and cooling, and helps Hengli Petrochemical (Dalian Changxing Island) project to achieve effective energy saving.

Hengli Petrochemical (Dalian Changxing Island) Industrial Park project total 25 billion yuan, divided into two phases of construction. The project has the characteristics of large scale, strong production capacity, high technological level and low energy consumption. After the project is fully put into operation, the annual sales revenue will exceed 100 billion yuan. The construction of the project will play an important role in promoting the development of petrochemical industry in Changxing Island Port Industrial Zone, driving downstream industries to gather, and promoting the optimization of petrochemical industry structure in Liaoning Province.

The compression heat regeneration dryer uses the waste heat generated by the compressor in the compression process to regenerate the desiccant, and the compressed air is not consumed in the heating regeneration process, and the energy consumption of the entire adsorption and regeneration process is close to zero. At the same time, make full use of the high temperature heat of the compressed air directly into the regeneration adsorption layer, and its high temperature heat is absorbed by the adsorbent, reducing the heat load of the rear cooler. Thus, the consumption of cooling water is reduced accordingly, and the tremella compression heat is very energy-saving, which can achieve effective energy saving to a greater extent.
