【摘要】 延迟焦化已成为国内外劣质渣油加工的主要手段之一,其加工能力和技术进步近年发展较快。随着原料劣质化,现代延迟焦化多采用降低循环比和低压操作提高焦化液收,同时采用缩短生焦周期等措施提高焦化装置的处理能力。延迟焦化工程技术的发展主要体现在延迟焦化装置大型化、设备自动化、操作安全可靠等方面。延迟焦化的生产操作在控制污染物排放、污油回炼等方面有较大改善。更多还原

【Abstract】 Delayed coking process has become one of the main methods to process the low quality residue with rapid advancement of its processing capacity and technology.With the deteriorated feedstock,modern delayed coking is operated in low recycle ratio to increase liquid product and in short decoking cycle to enlarge it processing capacity.Its engineering technology development focuses on the large scale equipment,automatic equipment and operating safety etc.The pollution emission control and sludge treatment is improved greatly.更多还原
