Adsorption column simulation

1 inlet -> purified + loaded

Governing equations

The exact equations the solver works for a adsorption column — the same math shown in the app's "Theory" panel, not a black box.

$q_i$

amount of i adsorbed per kg of sorbent [mol/kg]

$q_{max,i}$

monolayer capacity — the ceiling the sorbent can hold

$b_i$

Langmuir affinity constant [1/Pa] — how strongly i sticks; the *ratio* between two components' b is the selectivity

$p_i$

partial pressure of i [Pa]

$W$

sorbent mass in the bed [kg]

$\dot n_{i,ads}$

molar flow of i captured [mol/s]

Parameters

adsorbent_mass [kg], isotherms {component: {q_max [mol/kg], b [1/Pa]}} (competitive Langmuir)
