Abstract:

By fully utilizing the waste heat of materials in the No. 2 pyrolysis gasoline hydrogenation unit in the ethylene plant in Maoming, some modification measures were taken including feeding the bottom materials of debutanizer directly to the depentanizer, adding another feeding source to the depentanizer, using hot separation instead of cold separation in the second-stage reaction and optimizing the heat-exchange network, and a high-pressure steam heater was installed to replace the second-stage reaction heater. As a result, the energy was saved, the raw material consumption and energy consumption of the unit were reduced, the product quality was improved, and the economic benefit was increased, achieving good economic and environmental benefits.
