Interpretation Introduction

(a)

Interpretation:

The rate (kgh) at which steam is produced needs to be determined.

Concept introduction:

The energy balance is the first law of thermodynamics in which energy can be neither created nor be destroyed is given as follows:

ΔH+ΔEk+ΔEp=Q+W

Here,ΔH= Change in EnthalpyΔEk= Change in Kinetic EnergyΔEp= Change in Potential EnergyQ= HeatW= Work done

Interpretation Introduction

(b)

Interpretation:

The volumetric flowrate of the steam produced by using steam tables needs to be determined.

Concept introduction:

The volumetric flowrate (V) is equal to the product of specific volume of steam and the rate at which steam produced is given as follows;

V=(m)×(V^)

Interpretation Introduction

(c)

Interpretation:

The volumetric flowrate by assuming the ideal gas behaviour needs to be determined and compared with volumetric flowrate calculated using steam tables.

Concept introduction:

The ideal gas equation is given as follows;

PV′=nRTV′=nRTPV′=mRTMP

The molar mass of water is 18 g/mol thus,

In one mole of water, there are 18 grams are presentSo, 1mol=18g

Interpretation Introduction

(d)

Interpretation:

The effect on the 35% of the thermal energy released due to the combustion process that does not produces steam needs to be explained.

Concept introduction:

Thermal energy is defined as energy coming from heat. The heat is produced due to the movement of tiny particles in an object. Amount of geat generated depends on the speed of the particles.

A pilot process is being planned to produce antibiotic P. Antibiotic P is a compound secreted by microorganism A during the stationary phase. To produce P, substrate S is required. The growth of microorganism A follows the Monod equation, with a maximum specific growth rate $\mu_m = 1 h^{-1}$ and a half-saturation constant $K_s = 700\ mg/L$.The pilot process uses a chemostat with a working volume of $1000\ L$. In this chemostat, the outflow is processed to separate microorganisms, which are then concentrated tenfold and recycled. A sterile medium containing $15\ g/L$ of substrate is supplied at a flow rate of $100\ L/h$, while the recycled flow (concentrated) contains $5\ g/L$ and is also fed into the chemostat.Microorganism A yields $0.5\ g$ of biomass per $1\ g$ of substrate consumed $(Y^M_{X/S} = 0.5\ g\ A/g\ S)$, and its death rate $(k_d)$ is negligible. Additionally, $1\ g$ of microorganism A produces $0.05\ g$ of antibiotic P per hour $(q_P = 0.05 g\ P/h\cdot g\ A)$, and $1\ g$…

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 $.
