摘　　要：乙烯、丙烯是石油化工的主要基础产品,在石油化工中占主导地位。乙烯收率、双烯收率是乙烯裂解装置重要的经济技术指标。乙烯原料费用约占生产成本的70%以上,提高装置双烯收率、降低单位产品的原料消耗,可大幅降低单位产品的成本,从而提升企业的竞争力。通过采取原料轻质化、优化裂解炉及急冷系统运行、压缩系统进行CCC控制等手段有效提高乙烯收率和两烯收率,装置加工能耗大幅降低。在提高乙烯收率的同时装置也出现了急冷油温度低、燃料气产量过大等问题,成为制约装置能耗进一步降低的瓶颈。如何能有效解决瓶颈问题成为下一步工作的重点方向。Ethylene and propylene are the main basic products of petrochemical industry and dominate the petrochemical industry.Ethylene yield and ethylene and propylene yields are important economic and technical indicators of ethylene plant.The cost of ethylene raw materials accounts for more than 70%of the production cost.Improving the ethylene and propylene yields of the plant and reducing the raw material consumption per unit product can greatly reduce the cost per unit product,thereby enhancing the competitiveness of the enterprise.The ethylene yield and the ethylene and propylene yields can be effectively improved by means of using light raw materials,optimizing the operation of cracking furnace and quenching system and adopting CCC control for compression system,and the processing energy consumption of the plant can be greatly reduced.While improving the ethylene yield,the plant encountered some problems such as low quench oil temperature and excessive fuel gas output,which became the bottleneck restricting the further reduction of energy consumption.How to effectively solve the bottleneck problem becomes the key direction of the next step.
