重油延迟焦化发展现状及展望

Development Status and Prospect on Delay Coking of Heavy Oil

延迟焦化是应用最广泛的重油加工技术之一。介绍了延迟焦化技术国内外发展现状,特别是可灵活调节循环比和可选择液收两种延迟焦化工艺。针对延迟焦化含硫焦的利用,介绍了CFB和IGCC两种方案。探讨了延迟焦化在新时期的发展趋势。

Delay coking is one of the most widely used heavy oil processing technologies.Introduced is development status of delay coking technology at home and abroad.Such two delay coking processes are described as flexibly adjustable circulating ratio and optional liquid recovery especially.Based on utilization conditions of sulfur-containing coke in delay coking,introduced are such two options as CFB and IGCC.Finally discussed is the development trend of delay coking in the new era.
