If in a rigid vessel of given volume, saturated vapor steam is in equilibrium with saturated liquid water at 323 .15 K and heat is transferred to the vessel until one phase just disappears. Which phase remains and determine its temperature and pressure and find out amount of heat transferred. Concept Introduction: During the heat transferred in the process, total mass and volume remains constant. So, the total volume after the heat transferred is same as total volume at 323 .15 K . So, find the total volume and mass at 323 .15 K using the saturated steam table and use them to find temperature and pressure after the heat transferred. The heat transferred in the process is defined as: Q = m ( U 2 − U 1 ) .... (a) Where m is the mass of steam, U 2 is the internal energy after heat transferred and U 1 is the internal energy before heat transferred.

Interpretation Introduction

Interpretation:

If in a rigid vessel of given volume, saturated vapor steam is in equilibrium with saturated liquid water at 323.15 K and heat is transferred to the vessel until one phase just disappears. Which phase remains and determine its temperature and pressure and find out amount of heat transferred.

In the production of ethyl acetate via reactive distillation, the column operates at 5 bar with an equimolar feed (ethanol + acetic acid) at 80°C. The reaction follows: \[CH_3COOH + C_2H_5OH \rightleftharpoons CH_3COOC_2H_5 + H_2O \quad (K_{eq} = 4.2 \text{ at } 80°C)\] Given: - NRTL parameters for all binary pairs - Tray efficiency = 65% - Vapor-liquid equilibrium exhibits positive azeotrope formation Calculate the exact minimum reflux ratio required to achieve 98% ethyl acetate purity in the distillate, assuming: 1) The reaction reaches equilibrium on each tray 2) The heavy key component is water

In a multi-stage distillation column designed to separate a binary mixture of ethanol and water, the mass flow rate of the feed entering the column is \( F \), and the distillate product flow rate is \( D \). The reflux ratio \( R \) is defined as the ratio of the liquid returned to the column to the distillate flow rate. For the ideal case, where the column operates at maximum efficiency, determine the **minimum reflux ratio** \( R_{\text{min}} \) when the relative volatility \( \alpha = 1.5 \).
