Abstract: Along with the development of large scale petrochemical equipment, reciprocating compressors tend to become larger with multiple throw types. In recent years, great progress has been made in the development and application of large reciprocating compressors in China. The maximum allowable continuous load on piston rod has been developed from 800kN, 1250kN up to 1500kN. But the maximum throws of domestic reciprocating compressors were still limited to 4 throw configuration in refineries. Based on the 600,000 t/a CCR unit of Sinopec Tahe Petrochemical Co., Ltd., 6M80 large reciprocating compressor was developed independently, thus realizing the localization of large 6 throw configuration reciprocating compressors. With the advanced computer aided design method and leading technology, the compressors have operated stably and reliably. The development of this model has produced products with independent intellectual property rights. Such compressors can replace the imported ones, therefore, the investment in equipment, delivery cycle and maintenance cost can be reduced, which has good economic and social benefits.
