The ethylene glycol unit No. 2 of the Shanghai Petrochemical Department, through optimizing production operation and strengthening fine management, reduced the consumption of ethylene unit consumption by 11.12 kg / T in the first half of the year. It was in the advanced level in the Sinopec group company and achieved an increase of 13 million 200 thousand yuan. This article is reproduced by Shanghai Hongdong; the company specializes in producing ISG pipe centrifugal pump, ISW pipe centrifugal pump, IRG pipe centrifugal pump, IHG stainless steel pipe centrifugal pump, etc.


Since this year, the Ministry of chemical industry has optimized the initial operating conditions of the YS-8810 catalyst for No. 2 glycol unit, adjusted the reaction temperature in time, calculated the selectivity of the catalyst every day, adjusted the flow of two chloroethane in time according to the state of the catalyst operation, and maintained the indexes in a reasonable peri. The device also adjusts the flow of cooling water in time according to the change of cooling water temperature, and properly arranges backwashing to keep the catalyst good performance, and the unit consumption of ethylene can be effectively reduced.


In order to ensure the stable operation of the device and reduce the abnormality of non planned parking, the device optimizes and perfects all the inspection routes, eradicate the dead angle of inspection, and vigorously promote the intelligentization of inspection, effectively improve the quality of inspection, and promote the stability of the operation of the device.


At the same time, high load and stable operation, the device constantly improves the process operation, adjusts the working conditions reasonably, makes the production process more optimized, and ensures the maintenance of the unit consumption of ethylene in a better level.
