aspen模拟出错 流程是油品分馏进热高分,后面接热冷低分 ...? aspen 用的7.3.2的版本 流程是油品分馏进热高分,后面有高分和低分, 模拟中气提塔B1进料是 冷低分液和热高分气,B1下面有蒸汽气提,打算B1上面出来石脑油馏分,剩下的馏分从塔底出来,不过现在一直模拟不过,还没有进行塔分离设定,自己是菜鸟,B1塔两股进料的位置和回流比不确定是否合适,希望可以得到大家的帮忙,谢谢模拟错误如下: *** SEVERE ERROR MATERIAL AND ENERGY BALANCES FAILED TO CONVERGE: CHECK COL-SPECS OR SUPPLY BETTER TEMPERATURE AND COMPOSITION ESTIMATES. *** SEVERE ERROR THE FOLLOWING STAGES DRIED UP: 25 A LIMIT OF 0.10000E-04 * SUM OF FEEDS WAS IMPOSED ON THE FLOW RATES. ** ERROR SPECIFIED CONDENSER TEMPERATURE (323.1500 K) IS LESS THAN BUBBLE POINT TEMPERATURE (327.8630 K).
