Learn from the advanced practices of the *Brothers section; there are rewards for correct answers – every response earns a reward, allowing us to grow and mature through these Q&A sessions. Short-answer questions: Additional information can be provided regarding the main reasons for water contamination in the syngas in the scrubber tower and the corresponding treatment methods. 1. Excessive load – reduce the load. 2. Large fluctuations in the system – maintain system stability. 3. Poor water quality in the system – control water quality. 4. Water contamination in the gasifier – reduce the amount of water fed in and increase the discharge of wastewater. 5. High liquid level in the carbon scrubber tower – lower the liquid level. 6. Damaged tray plates or demisters – shut down the system for maintenance depending on the extent of water contamination. 7. Excessive water flow on the tray plates of the carbon scrubber tower – adjust the water flow on those tray plates
Main causes of water in the syngas stream in the scrubber tower and treatment methods: 1. Excessive load – reduce the load. 2. Large fluctuations in the system – maintain system stability. 3. Poor water quality in the system – control water quality. 4. Water in the gasifier – reduce the amount of water fed in and increase the discharge of black water. 5. High liquid level in the carbon scrubber tower – lower the liquid level. 6. Damaged trays or demisters – shut down the system for maintenance depending on the extent of water contamination. 7. Excessive water flow on the trays of the carbon scrubber tower – adjust the water flow on those trays
