Yangzi petrochemical ethylene production has more than 550 thousand tons
This year, a good time to seize the Yangzi Petrochemical olefin product profitability Chuangxiao, keep the ethylene unit stable production of high load, 1-8 months of this year, ethylene production exceeded 550 thousand tons, an increase of 1.58% yield.
According to the high load of ethylene production in the presence of a "bottleneck" problem, Yangzi Petrochemical actively take care measures, focusing on the "heart" - ethylene cracking gas compressor, refrigerant compressor, ethylene propylene refrigerant compressor, two yuan ethylene refrigeration compressor, methane compressor operation, the change of "intensive care", closely monitor ethylene distillation column reflux pump running parameters of the key equipment in the process of operation optimization, strengthen management, responsibility for duty, responsibility to the people, "intensive care" measures are in place to ensure the safe and stable operation of ethylene.
In 2, ethylene propylene distillation tower top water cooler due to cooling water shortage, for high load production bottleneck of thermal effect, Yangzi Petrochemical developed a transformation plan, the ten circulating cooling water device is introduced, for the heat exchanger, in March of this year to complete the transformation, which laid the foundation for the summer high load production. At the same time, due to careful planning, proper safety measures, in the transformation of the investment process, the Yangzi Petrochemical to take the way of online processing, to avoid the 3 day of the ethylene plant plans to stop, 3 days to produce 710 tons of ethylene.
Around the quality optimization of ethylene feedstock, Yangzi Petrochemical operation mode of ethylene cracking furnace based on synchronous tuning, liquefied gas supply of raw materials, combined with different type of furnace, liquid phase and gas phase material into the way of scientific and reasonable collocation, has implemented a variety of production operation mode, optimization of ethylene cracking furnace liquid phase adjustment and the gas phase material inputs, precise operation, fine tuning, the production load to the best device, in the pyrolysis gas amount remains unchanged, the greatest degree of prolific ethylene, ethylene device to ensure high yield, output benefit maximization. The stone also finished 2 for ethylene cracking furnace BA-1102 liquefied gas feed system transformation, in 2 ethylene plant for the first time to achieve a single furnace pyrolysis gas, making ethylene liquefied gas inputs than previously doubled, to ensure stable and high yield of ethylene plant.
