摘　　要：为满足某7000 PCTC汽车滚装船项目各双燃料用户在不同工况下的需求,初步设计4个供气系统气化方案,采用ASPEN HYSYS软件对不同方案和不同工况进行参数模拟计算,根据计算结果对比分析各方案的经济性、常用工况下的设备运行状态、控制难度、检测方便程度以及高/低温淡水系统设计难度,结果表明,采用高温和低温两套水/乙二醇系统最优,该项目最终确定采用该方案。In order to meet the requirements of all dual-fuel users under different working conditions in a 7000 PCTC project,four preliminary vaporization plans were designed.The parameters of different plan under different working conditions were simulated based on ASPEN HYSYS software.The simulation results were further analyzed and compared from aspects of economy,equipment running state under common working condition,control difficulty,convenience of monitoring and design difficulty of high and low temperature fresh water system.The results showed that using high and low temperature two sets of water/glycol system is the best.This project finally decided to adopt this plan.
