Detailed Description

Vertex model to represent countercurrent multicomponent mass transfer of dilute components in an absorber or a stripper.

Modeling assumptions:

gas phase is mosty air
The HTU/NTU model is used for the computation
Isothermal conditions hold along the column
linear Vapor/liquid behavior of all trasferrable components (Herly law or constant KVL)
neglects variation of liquid and gas molar flows along the packing (CMO constant molar overflow)
neglects effect on bulk properties of solvent due to disoolved components
the mass each trasfer of each component is independent on the trasfer of the others
no Reaction with solvent

List of ports:

in1 [vapin] inlet of vapor streamVL to HtuNtu
out1 [vapout] outlet of vapor streamVL from HtuNtu
in2 [liqin] inlet of liquid streamVL to HtuNtu
out2 [liqout] outlet of liquid streamVL from HtuNtu

#include <libpf/units/HtuNtu.h>

Remarks

Warning: Requires the list of components to be populated before the construction; Thread safe:; Extendable:; Platform dependencies:
