摘要：

延长石油（集团）有限责任公司榆林炼油厂（榆炼）1.8 Mt/a重油催化裂化装置通过实施多项节能措施，包括使用MIP技术、快速床-湍流床高效再生技术、中压蒸汽背压透平驱动主风机组、二级除盐水回收低温热、新鲜水作为吸收剂冷却介质、提高稳定塔操作压力降低循环冷水消耗、余热锅炉采用多级过热器以降低燃料气消耗，装置能耗小于41.5 kgoe/t。主风机组发电补充全厂用电，年创效3560万元，并节省发电上网、用电下网管理费用1000多万元。相较于某重叠式两段再生催化裂化装置，快速床-湍流床两段再生催化裂化装置折合单位体积流量烟气发电量是其2.2倍。采用沉降器旋分直联+粗旋料腿末端溢流斗料封防结焦技术，降低油气在沉降器停留时间，减少生焦进而降低能耗。装置达到“安、稳、满、长、优”生产目标，成为标杆性生产装置。

Abstract:

The 1.8 Mt/a residual oil catalytic cracking unit (RFCCU) at the Yulin Refinery of Yanchang Petroleum (Group) Co., Ltd. has implemented multiple energy-saving measures, including MIP gasoline olefins reduction reaction technology, turbulent-fast bed efficient regeneration technology, four-machine set of the main air driven by medium-pressure steam back-pressure turbine, low-temperature heat recovery by two-grade demineralized water, fresh water as the cooling medium of the absorber, increasing the operating pressure of the stabilizer to reduce the consumption of circulating cold water, and multi-stage superheater for the waste heat boiler. The energy consumption of the unit is less than 41.5 kgoe/t. The four-machine set supplements the power supply for the whole refinery, achieving an annual efficiency of 35.6 million yuan and saving over 10 million yuan in the management cost of to-grid and off-grid. The equivalent unit volume of flue gas power generation per cubic meter of flue gas is 2.2 times that of a superposition two-stage regenerative FCCU. The use of settler cyclone separator direct connection and overflow bucket at the end of the primary cyclone leg to prevent coking can reduce the residence time of oil and gas in the settler, reduce coke generation, and energy consumption. The RFCCU has achieved the production goal of “safety, stability, full capacity, long running time, excellence,” becoming the benchmark production unit.

Key words: RFCCU, energy consumption, MIP process, efficient regeneration, main air blower, steam step-by-step utilization, anti-coking, waste heat boiler
