Abstract:

In 2016, deep-cut revamping and heat exchanger network optimization were carried out on the 2.5 Mt/a atmospheric and vacuum distillation unit in Yumen refinery. The inlet temperature of crude furnace was increased from 260℃ to 310℃ after the integration and optimization of heat exchanger network. Through the deep-cut revamping of vacuum tower including the transformation from lubricating oil type to fuel type, the vacuum ejector system, the vacuum furnace and the vacuum transfer line, the TBP cut point of crude reached 565℃, the yield of VGO was improved by 6.47%, thus optimizing the feed to FCC unit. The yield of VR was decreased by 6.86%, reducing the load of DCU and improving the economic benefit of the refinery.
