Abstract
The article summarized the energy-saving technology for solution polymerization of synthetic rubber and the development of the energy-saving rubber in Beijing Yanshan Petrochemical Co., Ltd. (BYPC). Through improving the catalytic system, enhancing the reaction speed, hence increasing the produce of the reactors, adopting the polymerization reactor equipped with a blade integrated agitator, as will as improvement of the process technology and equipment in the polymerization, coagulation and solution recovery sector, the energy consumption of cis-PBR in BYPC has been continuously decreasing and has reaching the international advanced level. The commercialization of the heat pump technology in the agglutination of the solution polymerization for the synthetic rubbers can help reduce the consumption of 1 MPa LP steam by 0.72 t per ton of rubber. BYPC is now working on the direct devolatilization of the rubber solution and the gas phase polymerization of Poly-butadiene rubber. Technology development is also undergoing for new energy-saving synthetic rubbers such as SSBR, mid-vinl-polybutadiene rubber, SIBR and SBS, among which the technology for SSBR and SBS have already been commercialized.
