PRO*HHC Exercise:
Scenario: A factory discharges wastewater containing high levels of trichloroethylene (TCE), a halogenated hydrocarbon.
Task: Design a simple treatment system using PRO*HHC to reduce the TCE concentration in the wastewater before it is discharged into a nearby river. Consider the following factors in your design:
- PROHHC Catalyst:You have access to a fixed amount of PROHHC catalyst.
- Reactor: You need to choose a suitable reactor type (e.g., packed bed, fluidized bed, etc.) for the process.
- Operating Conditions: Determine the optimal operating conditions (temperature, pressure, flow rate) for the chosen reactor.
- Monitoring: How would you monitor the effectiveness of the treatment system?
Instructions: Briefly describe the design of your system, including the chosen reactor type, operating conditions, and monitoring methods.
Exercice Correction
**Treatment System Design:**
**Reactor:** A packed bed reactor is suitable for this application. The PRO*HHC catalyst can be packed within a column, allowing the wastewater to flow through the bed. This design ensures good contact between the catalyst and the wastewater.
**Operating Conditions:**
- Temperature: The PRO*HHC catalyst is designed to be effective at relatively low temperatures. A temperature of 50-70°C would be suitable.
- Pressure: Atmospheric pressure is sufficient for this application.
- Flow Rate: The flow rate should be adjusted to ensure adequate contact time between the catalyst and the wastewater. A slower flow rate allows for better TCE degradation.
**Monitoring:**
- **Regular TCE Analysis:** Samples of the treated wastewater should be taken regularly and analyzed for TCE concentration using techniques like gas chromatography. This allows you to monitor the effectiveness of the system.
- **Catalyst Performance:** The catalyst's performance should be monitored for signs of degradation or loss of activity.
- **Wastewater Discharge:** Regularly monitoring the TCE levels in the wastewater discharge stream ensures compliance with environmental regulations.
