H2S Scavenger

Hydrogen Sulfide Scavenger

DTM Triazine

DTM Triazine is a proprietary liquid chemical used for the instantaneous removal of hydrogen sulfide (H2S) from natural gas. It is an H2S scavenging chemical that will not absorb CO2. The reaction by-product of H2S with DTM Triazine is a sulfanated amine that will act as a mild corrosion inhibitor that is water soluble. It will not cause plugging down-hole or foaming in a downstream TEG dehydration unit.

DTM Triazine removes as much hydrogen sulfide (H2S) per liter/gallon as generic triazine and does it at a lower cost per liter/gallon. DTM Triazine is used to remove from 5 ppm to 1000 ppm (one thousand ppm) H2S from natural gas


Cost Comparison
DTM Triazine - $8.88 to remove 1.7 lbs H2S
Generic Triazine - $12.00 to remove 1.7 lbs H2S



Calculating Triazine H2S Scavenging Rates

Generic Triazine
0.2 liters x ppm H2S x MMSCFD = Generic Triazine Liters

DTM Triazine
0.148 liters x ppm H2S x MMSCFD = DTM Triazine Liters

Convert liters to gallons
3.785 liters = 1 gallon


DTM Triazine Comparison Example

Gas Well Flow Rate: 1 MMSCFD with 100 ppm H2S (parts per million)
Gas pipeline Specification: 4 ppm H2S
Scavenger Requirement: Remove 96 ppm H2S

Generic Triazine: 0.2 x 96 x 1 = 19.2 liters
DTM Triazine: 0.148 x 96 x 1 = 14.2 liters

Convert to Gallons
19.2 / 3.785 = 5.07 generic triazine gallons per day required
14.2/ 3.785 = 3.75 DTM Triazine gallons per day required

DTM amines are excellent H2S scavengers for use in towers. DTM amines are non-corrosive and will not form precipitates. DTM50 is not a selective amine. It will remove CO2 first and then H2S. Sour gas streams with little CO2 will find DTM50 very economical with acid gas loading of 0.271 lb/moles per gallon of DTM50.
