Installation andStart Up Procedures

Follow Your Company's
Safety Precautions:

  • ALWAYS FOLLOW YOUR COMPANY'S SAFETY PROCEDURES.  PRIORITIZE THE WELL-BEING OF ALL PERSONNEL INVOLVED. IF ANY SAFETY CONCERNS ARISE, HALT OPERATIONS AND ADDRESS THE ISSUE BEFORE PROCEEDING.  

  • Always use personal protective equipment (PPE) such as gloves, safety goggles, and respiratory protection.

  • Ensure all personnel are trained in H2S safety and emergency procedures.

  • Maintain clear communication with team members throughout the startup process.

  • Use H2S gas detection devices to monitor H2S levels continuously.

  • Keep emergency response equipment, such as breathing apparatus and first aid kits, readily available.

System
Layout:

  • "Saturate, Separate, Eliminate (i.e. sweeten)."  The proper equipment should be installed in the order shown below. 

    • Water injection.  If gas is undersaturated, located water injection about 20 feet upstream of the separator.

    • Separator. Please the separator 20-50 feet upstream of the sweetening vessel.

    • Sweetening vessel/Support Bed. The sweetening vessel should be piped for down-flow gas, and configured with a media support bed similar to the diagram to the right.

Loading
the Vessel:

  • Load the product through the top manway per the diagram to the right.

  • Fill to about 2' below the inlet gas pipe.

  • Level out the bed by pushing the coned material to the edges of the vessel. Continue loading the specified amount of product in the vessel(s).

Commencing
Gas Flow:

  • When the vessel is fully loaded and the manways are sealed, close the outlet gas valve from the vessel and slowly open the inlet valve to allow gas to fill the vessel slowly over 30-60 minutes.

  • When the vessel is fully pressurized, open the inlet valve fully and slowly open the outlet valve until the downstream system is fully pressurized, then open the valve fully or to the desired setting.

Monitoring
and Adjustment:

  • Allow gas flow through the vessel for 30-60 minutes, then take inlet and outlet H2S readings (using Draeger or similar tubes) to confirm conditions match the EPS.

  • Check the inlet gas water content (using Draeger or similar tubes), then the outlet gas. If the inlet water is higher than the outlet, the system is fully saturated. If the inlet water is lower, start water injection immediately, increasing until the inlet water reading is higher than the outlet.

  • Allow the system to stabilize, reaching full H2S removal capacity.

Performance Verification:

  • Confirm conditions like pressure, temperature, and flow rate. If different from EPS, request an updated EPS from the media vendor.

  • After equilibration, verify the outlet H2S concentration is within the desired range.

  • Fine-tune flow rates and parameters to achieve optimal H2S removal.
