进料100m3/h,温度是45~60之间,压力条件一概不知。然后塔底通入一股空气,要求精馏后的结果是塔顶产品中氨含量为0.3%~0.5%,塔顶的氨含量尽可能高点吧。我计算后老出现下面的错误
** ERROR
RADFRAC NOT CONVERGED IN 200 OUTSIDE LOOP ITERATIONS.
*** SEVERE ERROR
THE FOLLOWING STAGES DRIED UP (VAPOR OR LIQUID FLOW APPROACHES 0):
5
A LIMIT OF 0.10000E-04 * SUM OF FEEDS WAS IMPOSED ON THE FLOW RATES
OR A LIMIT OF 0.10000E-04 WAS IMPOSED ON THE STAGE V/L OR L/V RATIO.
请各位帮忙告诉下是啥原因,谢谢了~
