Maoming Ethylene Cracking Plant Standard
The No. 2 cracker with a designed capacity of 640,000 tons is the first domestically produced ethylene plant in China. The localization rate of equipment is as high as 87.8%. In the year when it was put into production in 2006, together with the new downstream installations, it created several highlights of the most investment-oriented, largest scale, independent innovation and high-level driving. Its safe and economical operation can bring a demonstration effect to the operation of domestic ethylene plants.
However, due to various reasons, since the device was put into production in September 2006, ethylene production has not reached the design value, and it has become a “short board†for ethylene safety production. At the beginning of this year, Maoming Ethylene formulated tasks, responsibilities, and practice assessment standards. It quantified and refined 10 important inspections, general indicators, basic work, and key indicators. To further leverage the incentive mechanism, they also set up a managerial incentive fund to refine the annual 1 million tons ethylene target to the month. For economic and technical indicators such as energy consumption and material consumption, they will strive to strive to ensure that these three steps will be rewarded, motivate employees to target, and promote economic and technological advancements. At present, the energy consumption per ton of ethylene has fallen by 52.6 kg of standard oil compared with the same period of last year. The loss rate of ethylene has dropped by 0.09%, equivalent to saving 2,592 tons of raw materials.
This year, they also solved a series of major problems such as the frequent blocking of cracking furnaces, the shaking of three cracking furnace tubes, and the lack of expander capacity, which played a decisive role in increasing the equipment load.
