Distillation column calculation
Thread Content
May I ask how to calculate the material balance and the number of trays required in a distillation column that discharges material only from the top and not from the bottom?
Material is only discharged from the top, not from the bottom. According to the law of conservation of mass, the same amount enters as exits; since everything comes out from the top, how can there be any separation capability? Where does the calculation of the number of plates come from?
In this way, the desired product gets concentrated at the bottom of the tower
Continuous operation only discharges from the top, with no discharge from the bottom. It is to first concentrate the desired product to a certain extent at the bottom, before allowing it to emerge simultaneously from both the top and the bottom; in other words, it is aimed at accelerating the time required for equilibrium in continuous distillation. So I want to calculate the separation situation during the period from the start of the experiment until actual continuous feeding and discharging
ASPEN’s Batch module is a reactor; that isn’t suitable, right?
