In this model, we use data taken from the operation to capture CO2
case design by DEPG Reported by Energy Systems Division, Argonne National Laboratory
( ANL) [1]. The Report includes an
absorb flowsheet for CO2 absorption by DEPG at elevated pressure, flash tanks to release CO2 and regenerate
solvent pressure at Several Different Levels, and
compressors and turbines to change Pressures of streams. However, the present model
process focuser in this work only on the absorption unit and the
Other Operations Are Not included. The sour gas
Enters the bottom of the absorbing, contacts with
propylene carbonate read from the solvent top counter-currently and leaves at the top as
sweet gas, while the solvent flows out of the absorber at the bottom as the
rich solvent with absorbed CO2 and some other gas components.
Two pressure levels for absorption were evaluated in the ANL report: 250psia
and 1000psia. For each pressure case study, the gas feeds into the absorber
is the same, but solvent flow rates and number of equilibrium stages used are
different. Typically, to achieve a certain CO2 recovery, the high pressure case
used less solvent and fewer stages. Table 2 represents some operation data.
In this propylene carbonate model, we used the operation data of the low
pressure case.
