摘　　要：为了更好满足下游的天然气需求,并减少压力能的浪费,以某天然气站为例,采用化工流程模拟软件Aspen Hysys对该天然气站的单级膨胀发电量、相关参数进行敏感性分析,并对可利用的冷能进行模拟仿真。通过分析表明采用的单级膨胀压差发电工艺中,随着入口流量和入口温度的增加,发电量也会相应增加,因此适当的提高入口天然气温度以及天然气流量可提高工艺的发电量。并根据分析结果针对冷能利用进行方案设计,有效地提高了能量的利用效率。Combined with the actual pressure regulation of a natural gas plant,the chemical process simulation software Aspen Hysys was used to simulate the power generation of single-stage expansion,the sensitivity analysis of related parameters and the available cold energy,and find the optimal working parameters.The scheme design is carried out for the utilization of cold energy,and the efficient utilization of energy is realized by combining the existing cooling water circulation pipeline in the plant and station.
