New Hydrogen Sulfide Scavenger Comparison Method for Natural Gas

Have you ever tried to evaluate hydrogen sulfide (H₂S) scavenger effectiveness and had a hard time transferring the gas sample to your laboratory? Had to start field testing H₂S scavengers without a reliable laboratory result? Or wanted to determine whether your scavenger is losing effectiveness?

Evaluating H₂S scavengers can present many challenges to the natural gas industry. The team at Lipesa, a ChemTreat-affiliated company, has developed a reliable new field method for comparing the efficiency of scavengers in hydrogen sulfide removal.

The method consists of connecting to a natural gas line at the scrubber outlet after the gas pressure has been reduced to less than 250 psig. From there, use a fine pressure control valve (needle valve) to lower the pressure to less than 50 psig so the gas can move through a container where a solution of the scavenger to be tested has been placed. You can then measure the H₂S content in the gas with and without product.

This method will help you:

• Evaluate scavengers directly in the field without having to take samples and transfer them to a laboratory. This eliminates the risks associated with transporting pressurized vessels and the possibility of H₂S loss during the transfer.
• Perform field tests with the knowledge that you have selected the best product for your application without needing to spend large sums of product and money on evaluation.
• Verify the scavenger currently used in your facility has maintained its efficiency.

This testing method will allow natural gas plant operators to verify which H₂S scavengers work best for their system needs. Please contact us to learn more. For more information regarding our offerings for the oil and gas industry, click here.
