DG Wet scrubber Commissioning checklist

Pre-Commissioning Checks

Review design specifications for wet scrubber

Verify all components are properly installed

Conduct visual inspection for any damage or defects

Ensure all connections are tight and secure

Check for any leaks in the system

Verify that all instruments and sensors are properly installed and connected

Ensure that all valves are in the correct position

Perform a pressure test to check for any leaks or weak spots in the system

Verify that all control settings are programmed correctly

Conduct a thorough inspection of the exhaust system to ensure proper ventilation and airflow

Check that all safety features and alarms are functioning properly

Electrical Checks

Verify proper electrical connections

Check control panel for correct wiring

Test emergency stop button

Verify power supply to wet scrubber

Test water flow through scrubber

Testing and Calibration

Conduct performance testing with simulated gas stream

Measure pressure drop across scrubber

Calibrate pH sensors if applicable

Verify proper operation of control system

Conduct flow rate testing to ensure proper air flow through the scrubber

Check and calibrate any temperature sensors within the scrubber

Perform a leak test to ensure there are no air leaks in the system

Verify proper operation of any alarm systems connected to the scrubber

Conduct a water quality test to ensure the scrubber is effectively removing contaminants

Startup Procedure

Fill scrubber with appropriate liquid

Start fan motor and adjust speed

Monitor system for leaks or abnormal noises

Adjust settings as necessary for optimal performance

Ensure all valves are in the correct position for startup

Check all electrical connections for proper functioning

Verify that all alarms and safety features are working correctly

Conduct a test run with the system to ensure all components are operating as intended

Monitor and record key performance indicators such as pressure, temperature, and flow rates

Adjust fan motor speed as needed to achieve desired scrubbing efficiency

Conduct a final inspection of the entire system before putting it into full operation
