4-23. A mixture of ethanol (A) and water (B) is separated in a distillation column. The volumetric flow rate of the feed stream is 5 m/hr. The concentration of ethanol in the feed is c,=2,800 mol/m. The distillate leaves the column with a concentration of ethanol c, 13,000 mol/m. The volumetric flow rate of distillate is one cubic meter per hour. How much ethanol is lost through the bottoms of the column, in kilograms of ethanol per hour?

Transcribed Image Text:**Problem 4-23: Separation of Ethanol and Water in a Distillation Column**
A mixture of ethanol (A) and water (B) is separated using a distillation column. The details of the process are as follows:
- **Feed Stream**:
- Volumetric flow rate: 5 m³/hr.
- Concentration of ethanol: \( c_A = 2,800 \, \text{mol/m}^3 \).
- **Distillate**:
- Concentration of ethanol leaving the column: \( c_A = 13,000 \, \text{mol/m}^3 \).
- Volumetric flow rate of the distillate: 1 m³/hr.
**Problem Statement**:
Calculate the amount of ethanol lost through the bottoms of the column in kilograms per hour.
