Recently, the first domestic 816 extra large styrene tail gas screw compressor independently developed by CSIC 711 was successfully put into operation on the 260,000 t/y styrene plant in Anhui Wuyuan. The equipment was successfully driven once.
The large styrene unit has a large exhaust gas flow rate, high pressure ratio, toxicity, flammability and explosiveness, and the medium is prone to polymerization. The requirements on the compressor are extremely high.
In 2016, 711 undertook the annual production of 260,000 tons of styrene screw compressor unit of Anhui Wuyuan Chemical Group. This is the first 816 large-scale styrene tail gas screw compressor in China. Compared with screw compressors of other similar projects, The energy consumption is reduced by more than 10%, and the energy saving effect is remarkable. The successful development of this type of tail gas screw compressor has broken the monopoly of foreign companies in the long-term styrene plant, filling the domestic gap and laying a solid foundation for expanding the field of large styrene devices. basis.
