Recently, the advanced control project of Changling Delayed Coking Unit successfully passed the acceptance review of Information Management Department of Headquarters.
Changling refinery delayed coking unit advanced control project is the headquarters of advanced control technology to promote the use of the project, the petrochemical PCCW Information Technology Co., Ltd. and Changling Petrochemical cooperation in the development, the use of the United States Honeywell Robust Multivariate Predictor of Frontier Control Technology, project covering coking unit heating furnace, fractionating tower and absorption stability of three units, through the furnace efficiency, fractionation tower and the absorption of the three stabilizers to achieve the diesel dry point, dry gas carbon content and other quality indicators real-time online Control, achieve the purpose of multi-variable coordinated control of the device.
Entrusted by the Information Management Department of the headquarters, Changling Refinery Science and Technology Development Division organized relevant experts to carry out a series of acceptance tests on the advanced control projects of delayed coking units. After the advanced control system was put into operation, the standard deviation of the key control indicators of the equipment was reduced by 20% , The control of the heating furnace is closer to the optimal operating point, which not only improves the smooth operation of the device, realizes the diesel quality optimization control, but also greatly reduces the energy consumption of the device, reaches various technical indexes and meets the acceptance criteria.
