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 2.15 kg neat triazine per kg H₂S (1 mol triazine → 2 mol H₂S) with user-specified active efficiency. Per NACE SP0192 and GPSA §21.
