H₂S Scavenger (Triazine) Calculator

MEA-triazine dose, volume & cost — NACE SP0192 / GPSA §21

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.

Equations

H₂S mass removed:

lbH₂S/day = Δppm·10⁻⁶ · F · 24 · 0.0898  (F in scf/hr)

Neat triazine dose:

mneat = 2.15 · mH₂S / η

Product volume:

Vproduct = mneat · (100/W%) / (SG · 8.34)
