Calculate liquid triazine H₂S scavenger dose for small sour-gas streams where an amine plant is uneconomic. Mass-balance and product-volume rates assume stoichiometry of 3.21 kg neat triazine per kg H₂S (2 mol H₂S → 1 mol triazine, the field-accepted basis) with user-specified active efficiency. Per GPSA §21 (gas treating) and the MEA-triazine 2:1 field stoichiometry.
