Sinopec Shanghai initiates a one-year intelligent transformation of its ethylene plant
Thread Content
On June 19, the centralized upgrade project for the control room of Shanghai Petrochemical’s olefins department commenced, with a construction period of approximately one year. Upon completion, the project will significantly enhance the intelligence level of the equipment, improve its automatic control and stability, and promote the high-quality development of the enterprise. Shanghai Petrochemical is one of the major ethylene producers in China. The full-process optimization project for its ethylene production facilities has been completed, but the central control system, which has been in use for decades, is relatively outdated, which hinders the high-quality development of these facilities. Once the upgrade and renovation project is completed and put into use, the intelligence level of Shanghai Petrochemical’s ethylene plant will be among the highest in China. The central control system will be able to automatically respond to various data changes, essentially replacing manual operations and thus improving the accuracy of operations.
Is APC control used in the intelligent transformation? Advanced control schemes, commonly known as edge-following operations.

How many years has the ethylene plant at Shanghai Petrochemical been in operation?
It’s not some new term; at least I’ve known about it for over a decade!
Built in the late 1980s, these facilities were part of four ethylene production units with a capacity of 300,000 tons per year – those in Beijing Yanshan, Nanjing Yangzi, and Shandong Qilu – all constructed around the same time. At that period, they represented the cutting-edge level of technology in the world. After two rounds of upgrades, the production capacity of these ethylene plants was increased from 300,000 tons to 400,000–450,000 tons per year, and then further to 600,000–700,000 tons per year.
These are all Sinopec’s enterprises; have the other three sets already been upgraded to be intelligent?
It seems not yet; we are waiting for the successful experience gained from the intelligent transformation of Jinshan Petrochemical.
It’s about avoiding even the slightest excess – sixty points is perfect; sixty-one points represents waste. -------------------------- Edge-control operations involve manipulating control variables to ensure that the product quality meets the required standards, thereby achieving the highest yield of the desired product while minimizing the energy consumption of the processing equipment, and thus maximizing the economic efficiency of the system.
