In the case of unexpected equipment failure in the granulation system of the polypropylene plant of Maoming Petrochemical Ethylene Plant, the plant took countermeasures for artificially packaged powders to ensure that the market supply was kept constant and maintained the momentum of ethylene production at full capacity. At present, Maoming ethylene produces more than 3,000 tons of ethylene per day, reaching the upper limit of design capacity, achieving a profit of more than 10 million yuan per day, and the rate of production and sales reaching 99%.
