H2S in the gas stream is reacted with scavenger chemical (Liquid Triazine or solid Iron Oxide) in to an innocuous, nonhazardous compound with no result in emissions. The scavenger chemicals are not regenerated for future natural gas treatments. Since these chemicals are to be replaced there might be high cost associated with these units. Absolute will decide based on the gas conditions to analyze which type of process is more economical and effective in removal of H2S.
