3. Explain the principles of distillation as applied to monomer recovery.

• Distillation is a separation process that utilizes the differences in volatility between components in a mixture.
• In monomer recovery, distillation is used to separate the monomer from other components in the process gas.
• The process involves heating the mixture to a temperature where the monomer vaporizes, and then condensing the vapor to collect the purified monomer.

4. Describe the different types of distillation columns used in monomer recovery and their advantages and disadvantages.

Different types of distillation columns used in monomer recovery include:

Packed Columns

• Advantages: High separation efficiency, low pressure drop.
• Disadvantages: High capital cost, prone to fouling.

Tray Columns

• Advantages: Simple design, low capital cost.
• Disadvantages: Lower separation efficiency, higher pressure drop.

Membrane Columns

• Advantages: Highly efficient, compact, low energy consumption.
• Disadvantages: Expensive, limited to certain applications.

5. Explain the importance of corrosion control in monomer recovery systems and discuss the methods used to mitigate corrosion.

Corrosion is a major concern in monomer recovery systems due to the presence of highly corrosive chemicals.

Methods to Mitigate Corrosion

• Material Selection: Using corrosion-resistant materials such as stainless steel or titanium.
• Protective Coatings: Applying protective coatings or linings to metal surfaces.
• Corrosion Inhibitors: Adding corrosion inhibitors to the process streams.
• pH Control: Maintaining the pH of the process streams within acceptable limits.
• Regular Inspection and Maintenance: Regularly inspecting and maintaining equipment to identify and address potential corrosion issues.

6. How do you handle and store recovered monomer to maintain its quality and prevent contamination?

• Store the monomer in appropriate containers that are compatible with the material.
• Maintain proper storage conditions, such as temperature, humidity, and light exposure, to preserve its quality.
• Implement measures to prevent contamination, such as using clean equipment and handling procedures.
