HIGH-EFFICIENCY CONVERSION ENGINEERING SOLUTION FOR INFERIOR RESIDUE

Aiming at the problem of unqualified high sulfur coke delivery in delayed coking unit caused by processing heavy and inferior crude oil, a high-efficiency conversion engineering solution for inferior residue was developed. Several new technologies were integrated into catalytic cracking unit, including reactor anti-coking technology, feed oil emulsification and atomization technology, 10 MPa grade steam generation technology, separation and processing technology of LCO and HCO, absorption and stability system energy-saving technology and flue gas purification technology, etc. The new solution can be used to carry out high-efficiency catalytic cracking for inferior residue in refineries and partially replace delayed coking technology to solve the problem of low value-added and high sulfur coke. The solution can increase liquid product yield, and reduce energy consumption of the unit and the whole plant.It is environmentally friendly and conductive to the FCC process, which breaks through the bottleneck of feedstock selection and significantly improve the economic benefits of refineries.
