摘要
为减少船舶运输中CO_(2)排放,基于Aspen Plus构建船舶尾气碳捕集模型,通过中试实验数据验证其可靠性(模拟值与实验值相对误差<5%)。优化分析表明,吸收塔填料高度7 m时,再生能耗降至4.28 GJ/t CO_(2),吸收剂流量减少16%;液气比1.11 kg/kg时,再生能耗最低(4.31 GJ/t CO_(2));富液再循环在15级注入时能耗降至3.996 GJ/t CO_(2)(降幅8%),富液分级流分流率12.5%时能耗降至3.97 GJ/t CO_(2)(节能4%)。
To reduce CO_(2)emissions from marine transportation,this study establishes a ship exhaust gas carbon capture model based on Aspen Plus and validates its reliability using pilot-scale experimental data(with a relative error of less than 5%between simulation and experimental results).Optimization analysis shows that when the absorber packing height is 7 m,the regeneration energy consumption decreases to 4.28 GJ/t CO_(2),with a 16%reduction in solvent flow rate.At a liquid-to-gas ratio(L/G)of 1.11 kg/kg,the lowest regeneration energy consumption is achieved at 4.31 GJ/t CO_(2).The rich solvent recycling process reduces energy consumption to 3.996 GJ/t CO_(2)at 15-stage injection(an 8%reduction),while the staged rich solvent splitting process lowers energy consumption to 3.97 GJ/t CO_(2)at a splitting ratio of 12.5%(a 4%energy saving).
