Simulation of Membrane Technology for CO2 Removal for cross-flow model using ASPEN HYSYS software

There are nearly 40% of the world gas reservoir contains high level of CO2 and H2S that
pose obstacles to development. Due to the high CO2 content, up to 13 trillion cubic feet
of high CO2-NG gas fields remain undeveloped in Malaysia. Therefore, development of
CO2-NG separation techniques will enable monetization of high CO2-NG gas fields in
Malaysia and to position PETRONAS the competitive edge for international fields’
acquisition. Many technologies have been developed for CO2 removal such as
adsorption, absorption, cryogenic distillation but membrane is the most optimized
technology.
In order to complete the existing simulation for the membrane in HYSYS software, the
temperature change between the inlet and outlet stream needs to be considered. The
reason that causes the temperature change is Joule-Thomson effect. By studying the
Joule-Thomson effect, the author can apply all the mathematical equations into the
HYSYS program to simulate the membrane. With the membrane simulation in HYSYS,
the chemical engineers will easily see the temperature change as well as other properties
(composition of CO2 content) in the outlet streams.
The membrane simulation is created in the help from Visual Basic 6.0, Visual Basic.Net,
C# and Matlab.
