At the feed inlet on side A, due to the operating conditions of the tower, some C5 evaporates from the top of the tower. According to material balance, the amount of C5 at the bottom of the tower decreases. This also depends on the actual operating conditions; if the conditions at the tower top are well controlled so that no additional C5 is emitted, then ultimately the amount of C5 at the bottom of the tower will not decrease either
There was a misunderstanding; I thought liquid hydrocarbons referred to the bottom of the tower. But my meaning was clear
