摘　　要：要实现催化裂化油浆高附加值利用,选择高效、低耗的油浆脱固技术尤为关键。对目前常用的催化裂化装置油浆脱固技术长期应用效果进行考察,结果表明:低温脱固技术原料适应性强,要求固含量不高于50 g/L,胶质质量分数不高于15%,沥青质质量分数不高于10%;脱固油浆固含量长期稳定在100μg/g以内,满足针状焦原料的要求;操作温度在160~180℃,相对较低,燃料消耗少,运行成本低;净化油浆收率高达99%,不产生反冲洗油或浓缩油浆;可实现固体与液态油浆彻底分离,排出粉状滤渣基本不含油,可作为一般固废处理;设备占地面积小,配套公用工程少,操作简单,均在常压或微负压下操作,生产运行安全系数高;可实现装置长周期连续生产,符合企业降本增效的发展需求。To achieve high value-added utilization of FCC slurry oil,it is particularly crucial to choose high efficient and low consumption slurry oil solid particle removal technology.Based on the long-term application of slurry oil low-temperature solid particle removal technology in FCC unit,it is proved that the technology has strong adaptability to feedstocks,with a solid content of no more than 50 g/L,a gum mass fraction of no more than 15%,an asphaltene mass fraction of no more than 10%,and the solid content of the desolidified slurry oil remains stable less than 100μg/g for a long term,which meets the requirements of needle coke feedstocks;the operating temperature is 160~180℃,which is relatively low,with low fuel consumption and low operating cost;the yield of purified slurry oil is as high as 99%,without producing backwash oil or concentrated slurry oil;solid and liquid slurry oil are completely separated,and the powdery filter residue is basically oil-free;the equipment occupies a small area,has few supporting public works,is easy to operate,and has low operating pressure,with a high safety factor in production and operation.It can achieve long-term continuous production of the unit,meeting the requirements of reducing costs and increasing efficiency.
