Shanghai Petrochemical , full name Sinopec Shanghai Petrochemical Company Limited , the subsidiary company of Sinopec, is one of the largest petrochemical enterprises in Mainland China. It is engaged in production of ethylene, fiber, resin and plastics. The company is registered in Shanghai.Its headquarters are in Jinshan District, Shanghai.There have been hopes that Sinopec, Shanghai Petrochemical's parent company, will process share reform and privatize Yizeng Chemical Fibre and Sinopec Shanghai Petrochemical, but the plan does not finalize until this moment.

The present invention relates to a process of producing oxalate by CO gas phase method for chiefly solving the technical problem of the low utilization efficiency of nitrogen oxides or nitrous acid esters in the prior art. The present invention solves the problem in a better way by using the following steps including: a gas phase stream V containing NO and methanol and oxygen enter a supergravity rotating bed reactor II and are subjected to the oxidative esterification reaction to produce an effluent VI containing methyl nitrite; a methyl nitrite effluent VII obtained from separating said effluent VI together with a CO gas II enter a coupling reactor II and is contacted with a catalyst II to react to form a dimethyl oxalate effluent VIII and a gas phase effluent IX containing NO; the resultant dimethyl oxalate effluent VIII is separated to obtain a dimethyl oxalate product I; optionally, the gas phase effluent IX containing NO is returned to the step above so as to be mixed with the gas phase stream V containing NO for being recycled. Therefore, the process is applicable to the industrial production of oxalate by CO gas phase method.

An apparatus for recycling propylene includes a first propylene recovery column, a flash tank, a second propylene recovery column, and a depropanizing column. The apparatus can effectively solve the problem of high power consumption in the prior art, and can be used for the industrial manufacturing of propylene recovery from a propylene oxide apparatus. A process for recycling and refining propylene also is described.
