摘要
风城超稠油属于低硫含酸的环烷基原油,依据风城超稠油的性质特点及加工难度,研究了风城超稠油原油蒸馏-延迟焦化工艺路线。结果表明:轻馏分可作为环烷基特种油原料,480~520℃馏分可经加氢脱氮处理后作为催化裂化原料,大于520℃馏分经延迟焦化处理可生产满足SH/T 0527—2019质量指标的1号低硫石油焦,为风城超稠油的加工利用提供了一条切实有效的途径。
Fengcheng super-heavy oil belongs to acidiferous naphthenic crude oil with low sulfur content. Based on the properties and processing difficulties of Fengcheng super-heavy oil, the distillation-delayed coking process route of Fengcheng super-heavy oil was studied. The results show that the light fraction can be used as naphthenic special oil raw material, the 480~520 ℃ fraction can be used as catalytic cracking raw material after hydro-denitrification treatment, and the higher than 520 ℃ fraction can be treated by delayed coking to produce 1# low-sulfur petroleum coke that meets the quality index of SH/T 0527—2019, which provides a practical and effective way for the processing and utilization of Fengcheng super-heavy oil.
