摘要
锦州25-1南油气田天然气终端项目需拟建一套处理规模为110万m3/d的轻烃回收装置,它的主体工程包括进站分离、天然气脱水、冷凝分离、凝液分馏、外输气增压等。
     本文对轻烃回收的目的意义、国内外现状、轻烃回收的方法和各种制冷工艺以及C3收率、能耗的计算和影响因素做了简单介绍。通过利用HYSYS软件的大量模拟计算,分析了C3收率与制冷温度和总能耗之间的关系,确定了膨胀机制冷温度为-85℃,C3收率不低于95%,丙、丁烷和轻油产品符合质量指标的最优工艺参数。
     针对本项目的特点对轻烃回收方案制冷工艺进行了优选,最终确定了膨胀机制冷加丙烷辅助制冷的同轴增压的轻烃回收方案。通过对工艺装置流程的模拟,对主要设备进行了选型,找到了最优化的工艺参数:丙烷预冷温度-35℃,膨胀机进口压力3890kPaA;膨胀机出口压力1400kPaA;低温吸收塔5块理论塔板;脱乙烷塔顶压力2100kPaA;脱丙烷塔20块理论塔板数;脱丁烷塔顶最佳回流比0.5;脱丁烷塔20块理论塔板数。论文最后提出了该工艺技术目前存在的问题和建议。
Light hydrocarbon recovery optimization of Jin Zhou 25-1 south oil and gas field naturalgas terminal project proposed to be a articles of the light hydrocarbon recovery unit, its dailytreatment capacity is 110,0000m3/d, and its main works include stop separation, gasdehydration and condensate separation, condensate fractionation ,increasing gas pressure andso on.
     This paper introduces the purpose and significance of light hydrocarbon recovery,domestic and international situation, light hydrocarbon recovery methods and a variety ofrefrigeration technology, as well as C3 yield and its influencing factors and its calculation.Through the use of a large number of HYSYS simulation software, the paper analysis therelationship between the C3 yield and the cooling temperature and the total energyconsumption, so it determines the cold temperature of the expansion mechanism is -85, C3yield is not less than 95%, propane、butane and light oil products comply with the best qualityindex.
     For the characteristics of this project, the paper optimizes the light hydrocarbon recoveryrefrigeration technology, and finalizes the light hydrocarbon recovery program: expansionmechanism coaxial cold + propane refrigeration.
     Through the simulation process technology devices to find the optimum processparameters: propane pre-cooling temperature is -35℃; inlet pressure of expander is3890kPaA; outlet pressure of expander is 1400kPaA; plates of low-temperature absorber are 5;central feed temperature of deethanizing tower is 0℃; plates of off the propane tower are 20;plates of de-butane tower are 20.
     Finally, the paper presents existing problems and recommendations of the technology.
