If too much water is added, or if the gas velocity of the syngas is too high, resulting in liquid droplet entrainment, water carryover will occur. Inside the scrubber tower, the syngas is washed using water supplied through the trays
The reasons for water in the carbon scrubber tower are: 1. Poor water quality in the system. 2. The gasifier is contaminated with water. 3. The system pressure fluctuates greatly. 4. High liquid level in the carbon scrubber tower……
Judgment: Check the system vibration and the changes in the level of the separator fluid. .
Judgment: Syngas outlet temperature, carbon scrubber tank level, syngas flow rate, high-pressure ash water pump inlet temperature, Shift 1 separation tank level.
Is the syngas outlet temperature higher or lower when water is present? Is the system water temperature determined from the inlet temperature of the high-pressure ash water pump?
It is still necessary to calculate the gas-liquid equilibrium; the amount of water used should not be increased excessively just to enhance the washing effect. Additionally, it is important to check whether the trays are clogged.
The most direct indication of water presence is a significant variation in the exhaust flow rate from the scrubber tower. Once signs of water presence are detected in subsequent processes, the trend of the exhaust flow rates is examined; the unit with the greatest fluctuations in its exhaust flow rate is addressed first, after which other factors are investigated: reducing the flow rate or diverting the gas to waste.
