Design the title, conditions, and content.

Title: Design of ethanol-water continuous distillation columns (sieve columns or float valve columns).

Basic conditions: the feed liquid containing ethanol 25 (mass fraction, the same below) enters the tower in the bubble point state, the reflux ratio is multiple of the minimum reflux ratio, the ethanol content in the product at the top of the tower is 94, and the residual liquid at the bottom of the tower contains ethanol. The tower has a production capacity of 10 tons of 94 ethanol products per day (24h).

The top pressure is 4kpa (gauge pressure), the pressure drop of the veneer is used, and the reboiler is heated by low-pressure steam.
