**Chlorination of Ethylene - Reaction Pathway and Process Diagram**

**Objective**: Prepare a material flowsheet similar to Figure 6.1 for the production of 2400 lb-mol/hr of Vinyl Chloride (VC) based on reaction path #5, ensuring to show the molar flow rates of all compounds in all streams.

**Reaction Path #5: Balanced Process for Chlorination of Ethylene**

1. **Reactions Involved**:
- $ \text{C}_2\text{H}_4 + \text{Cl}_2 \rightarrow \text{C}_2\text{H}_4\text{Cl}_2 $
- $ \text{C}_2\text{H}_4 + 2\text{HCl} + \frac{1}{2} \text{O}_2 \rightarrow \text{C}_2\text{H}_4\text{Cl}_2 + \text{H}_2\text{O} $
- $ 2\text{C}_2\text{H}_4\text{Cl}_2 \rightarrow 2\text{C}_2\text{H}_3\text{Cl} + 2\text{HCl} $
- $ 2\text{C}_2\text{H}_4 + \text{Cl}_2 + \frac{1}{2} \text{O}_2 \rightarrow 2\text{C}_2\text{H}_3\text{Cl} + \text{H}_2\text{O} $

2. **Operating Parameters**:
- **C**: 100% Conversion of Cl$_2$ at 80°C and 150 kPa with 15% excess C$_2$H$_4$
- **E**: 100% Conversion of HCl at 275°C and 150 kPa with 5% excess C$_2$H$_4$
- **D**: 75% Conversion at 500°C and 3000 kPa
- Water is separated from the mixture before entering reactor D.

Expert Solution

Step 1

The reactions are

$C_{2} H_{4} {+2Cl}_{2} {→C}_{2} H_{4} {Cl}_{2} ........(1) C_{2} H_{4} + 2 HCl + \frac{1}{2} O_{2} \to C_{2} H_{4} {Cl}_{2} + H_{2} O . . . . . . . . (2) 2 C_{2} H_{4} {Cl}_{2} \to 2 C_{2} H_{3} Cl + 2 HCl . . . . . . . . (3)$

Let us assume that all the HCl produced is recovered and is used a reactant.

Basis: 2400 lbmol/h of vinyl chloride

According to stoichiometry of reaction (3)

HCl produced = $2400 \frac{lbmol}{h}$

C₂H₄Cl₂ needed = $2400 \frac{lbmol}{h}$
