H2S Removal

The Importance of H2S Removal

Hydrogen Sulfide (H2S) is a very toxic gas that is dangerous for personnel and causes problems in both the upstream and downstream side of production in the oil and gas industry. Due to the detrimental effects of H2S, pipeline companies have specifications in place that prevent gas with high amounts of H2S to be put into the pipeline. CROFT offers two efficient solutions for removing H2S; our Amine Plant (GSS) and Chemical Injection System (CIS).

CROFT Amine Plant


CROFT designs and manufactures Gas Sweetening Systems (GSS) also referred to as Amine Plants. Our amine plants are rugged, all-in-one packages that can be utilized in split stream applications in order to treat grater volume amounts of H2S and CO2.

CROFT designs and manufactures gas sweetening amine plants with rates of up to 10 GPM of amine. Using the given parameters for your particular gas stream, we will design the most efficient system to handle your specifications.


  • Client training and onsite equipment orientations
  • Safely decreases H2S & CO2
  • Arrives with all components packaged on one skid
  • Compatible with a variety of amines


CROFT Chemical Injection System

Multi-Use Injection and No Toxic Emissions

CROFTs Chemical Injection System (CIS) is a multi-use chemical static mixer implementation. When used for H2S removal, the CIS is a safe and effective alternative to amine plants without the need for permits or large capital investment, operating without emissions and fired vessels. CROFT’s highly concentrated H2Scavenger efficiently removes H2S, decreasing the scavenger usage.

The CIS is ASME coded and uses solar injection pumps to eliminate emissions and maximize reliability. For H2S removal, the CIS is also NACE compliant.


  • Reduced capital and operating expense
  • No operational emissions
  • Economical; only use what is needed
  • Simple and safe maintenance
