The production of plastic, liquid chemical, rubber and acrylic fibers with ethylene as the leader has been the main business of Daqing Petrochemical. Since the beginning of this year, around the goal of “building a national first-class ethylene production enterpriseâ€, Daqing Petrochemical has been actively implementing a standardized management system and digging deep into the production potential, so that the old ethylene plant introduced in the 1980s will rejuvenate its youth, and the diene yield and ethylene energy Key performance indicators such as consumption and loss rate of ethylene equipment have been significantly improved.
As a leading company of Daqing Petrochemical Company, Chemical Plant 1 manages 8 major production facilities, including ethylene cracker and butadiene extraction plant. This plant creatively promoted a standardized management system, formed a fine management process centering on standardized inspection and standardization change management, and realized the operation of the device “safe, stable, long, full, and excellentâ€. In 2009, the unplanned shutdown was performed only once. With a year-on-year decrease of 5 times, the unplanned downtime was reduced by 45 hours compared to the same period of last year, laying the foundation for the rise in diene yield.
This plant optimizes and adjusts the operating conditions of the cracking furnace in time according to the changes in the quality of raw materials, and increases the number of analytical tests and frequency of the raw materials entering the plant. In view of the fact that the light hydrocarbon fluids and CO2 content of the oil field are high, measures such as the operation of tank sealing and the conversion of light hydrocarbons into the refinery are used to stabilize the quality of the raw materials, and the yield of diene is guaranteed from the source.
The plant has also developed internal control management indicators and benchmarking management programs to ensure that the process parameters of the equipment are operating in an optimal state within a narrow range. In order to ensure an increase in the yield of ethylene and propylene, the plant incorporates the process operating parameters into the economic accounting assessment of the team to clarify the responsibilities of the operating personnel and management personnel, strictly enforce the operating discipline, and effectively ensure that all process parameters affecting the yield of ethylene and propylene are always controlled. In the best condition.
Daqing Petrochemical Diene yields the best in the country
As of December 10, the cumulative yield of ethylene and propylene (diene) at Chemical Plant No. 1 of Daqing Petrochemical Company reached 49.67% (ethylene yield of 35.11% and propylene yield of 14.56%), creating the best in the country.
