摘　　要：目前我国石油化工领域生产过程存在较为严重的油气蒸发损耗问题,不仅导致油品资源的损耗,也严重影响了大气质量,常通过吸附方式进行油气回收。针对实际工业中油气吸附效率较低的问题,致力于寻求提高活性炭吸附性能的方法。基于计算流体力学软件中的组分输运及多孔介质模型,对油气吸附过程进行建模及动态模拟,分析活性炭床层内部的浓度场分布情况,并采用控制变量法对比空塔气速对吸附性能的影响。不同气速下穿透曲线的比对结果表明:气速越大穿透曲线越陡峭,相同时间间隔内的吸附负荷越大穿透时间越短。The oil&gas evaporation loss bothers petrochemical production at home,which leads to the loss of oil resources and seriously influences the air quality and the way of adsorption is employed generally for oil&gas recovery.In this paper,considering the poor efficiency of oil&gas adsorption in industry,the ways to improve adsorption performance of activated carbon was proposed.In which,having component transport and porous media models in computational fluid dynamics software based to model and simulate the oil&gas adsorption process was implemented,including analyzing the concentration field distribution within activated carbon bed and having control variable method adopted to compare the effect of superficial gas flow rate on the adsorption performance.The comparison of the penetration curves at different gas velocities shows that,the higher gas velocity can bring about steeper penetration curve and in the same time interval,the higher adsorption load results in shorter penetration time.
