It was learned from the Liaoyang Petrochemical Company's olefin plant that this plant continuously digested and absorbed foreign advanced technology and optimized the operating parameters of the plant, so that the annual 200,000 tons of ethylene glycol plant saved 24.98 million yuan.
The 200,000-ton ethylene glycol plant of Liaoyang Petrochemical's olefin plant uses the world-leading SHELL production technology and was completed and put into use at the end of 2007. After the new device is put into use, all the indicators such as the production capacity, product quality, and environmental protection of the device have reached the design value.
While applying imported technology and striving for stable operation, related technical personnel of Liaoyang Petrochemical found that the device consumption and energy consumption have been at a relatively high level. With no superstitious beliefs or blind obedience to foreign advanced technologies, Liaoyang Petrochemical has conducted energy-saving and energy-saving optimization researches around device consumption and energy consumption. On the one hand, a series of measures such as adjusting the ethylene concentration of circulating gas, reducing the concentration of carbon dioxide, optimizing the feed amount of monochloroethane, and increasing the methane concentration of the system, etc., have made the selectivity of the catalyst increase by 0.5% before optimization. At the same time, strict control of system emissions will reduce exhaust gas emissions from 900 kg/hr to 220 kg/hr. This alone can consume 130 kg of ethylene, 32 kg of oxygen and 210 kg of methane per hour, and save 15 million yuan annually. . On the other hand, to adjust the temperature at the top of the C204 tower, researchers regularly draw steam balance diagrams so that steam can be used reasonably. While meeting the production requirements, the replacement of the system's process water is reduced, the recirculating filter at the bottom of the distillation tower is regularly cleaned, and the treatment of steam running, dripping, dripping, and leaking is focused on, so that the medium-pressure steam consumption is 42 tons/hour. When it is reduced to 34 tons/hour, it is calculated according to the annual operating time of 8000 hours of the device. It saves 64,000 tons of medium-pressure steam, equivalent to RMB 9.98 million.
