请教 PROII一做了个粗苯多级蒸发的模拟
|

请教各位大侠: 我最近用PROII一做了个粗苯多级蒸发的模拟,提示如下: *** error *** Unit 1, 't101' - a product water decant stream is required but missing on tray 1. Please verify that the selected thermodynamics support vlle or vlwe. *** error *** Unit 1, 't101' - invalid variables - stream 105 has been varied more than once. ** warning ** Unit 2, 'e101b' - solids may exist in this flowsheet. The rigorous heat exchanger presently cannot handle solids and will fail to solve if any solids appear in feed streams of this unit operation. ** warning ** Unit 4, 'e101a' - solids may exist in this flowsheet. The rigorous heat exchanger presently cannot handle solids and will fail to solve if any solids appear in feed streams of this unit operation. |
