摘要：Most of the current research in process synthesis
focus on heat exchanger network synthesis. Reports on mass
exchanger network synthesis mostly discussed singlecomponent
problems using simultaneous approaches.
However, less attention has been given to mass exchanger
network synthesis with multi-component problems using the
sequential technique. Till date, it has not been easy to
systematically choose between the process and available
external mass separating agents (MSA) in mass exchanger
network synthesis during the adsorption of CO2. In this paper,
we set out a technique for targeting external mass separating
agent and its network design. The technique was applied to a
CO2 adsorption process involving two mass separating agents
(process and external MSAs) that overlap. A thermodynamic
analysis of the CO2 adsorption process was outlined in this
study using the composition interval method. Feasible
structures were formulated and the synthesis task was
expressed in a two-stage targeting procedure as an
optimization task. Unlike previous studies reported in the past
for mass exchanger network synthesis, this contribution
considers a trade-off between the process MSA S1 and external
MSA S2 to determine the minimum amount of external MSA
required for the CO2 capture process. A case study was
adapted from open literature to demonstrate the effectiveness
of the synthesized mass exchanger network during a typical
CO2 capture process. Outcomes from this study indicate that
mass integration via process synthesis is an effective strategy
that can minimize the quantity of external utilities required
during the adsorption of CO2 from a rich stream of flue gas.
