摘要/Abstract

摘要： 为了充分利用原油资源，渣油的高效加工至关重要。浆态床渣油加氢工艺因转化率高，被视为劣质重渣油轻质化的重要途径。根据A，B，C 三套3.0 Mt/a浆态床渣油加氢装置运行情况，对浆液分馏系统工艺设计特点进行分析，从浆液分馏系统设计、反应一次转化率控制、操作参数优化、设备内件选择等方面，提出浆液分馏系统长周期稳定运行优化策略。采用优化策略后，浆液分馏系统长时间未发生螺旋板内漏，减压塔压降和产品分离效果改善，浆态床渣油加氢装置可实现长周期运行。

Abstract: To maximize the utilization of crude oil resources, the efficient processing of residue oil is of paramount importance. Slurry bed residue oil hydrogenation technology, due to its high conversion rate, is regarded as a critical pathway for the upgrading of inferior heavy residue oil. Based on the operational performance of three 3.0 Mt/a slurry bed residue oil hydrogenation units (A, B, and C), an analysis of the process design characteristics of the slurry fractionation system was conducted. From perspectives such as the design of the slurry fractionation system, control of the primary reaction conversion rate, optimization of operational parameters, and selection of internal equipment components, optimization strategies for the long-term stable operation of the slurry fractionation system were proposed. After implementing these optimization strategies, the slurry fractionation system has experienced no spiral plate leakage over extended periods, and the separation efficiency of products has improved. Consequently, the slurry bed residue oil hydrogenation unit can achieve long-term stable operation.

Key words: residue hydrotreating, slurry fractionation system, coking, vacuum tower
