Ammonia scrubber (acid) simulation

gas + acid -> scrubbed gas, liquor at a set mole ratio, acid bypass

Governing equations

The exact equations the solver works for a ammonia scrubber (acid) — the same math shown in the app's "Theory" panel, not a black box.

$F_{abs}$

ammonia absorbed [mol/s]

$\eta$

ammonia recovery [-]

$F_{NH_3,in}$

ammonia in the gas [mol/s]

$\phi$

fraction of the acid sent to the contactor [-]

$MR$

liquor mole ratio [-]

$N$

ammonia nitrogen in the acid [mol/s]

$P$

phosphorus in the acid [mol/s]

$S$

sulfur in the acid [mol/s]

$MR_{liquor}$

liquor mole ratio [-]

Parameters

ammonia in a gas absorbed by acid; the liquor leaves at a set mole ratio and the acid not needed bypasses. mole_ratio [-] (required: the liquor's, e.g. 1.5 pre-scrubber, 0.7 tail-gas scrubber); ammonia_recovery [-] (required, the contactor's, measured); temperature [K] (default the gas inlet's). No water is condensed or evaporated
