EFFECT OF VARIOUS OPERATING CONDITION TO THE PERMEATION RATE OF CARBON DIOXIDE

The repot focus on acid gas removal technology that is membrane technology that
currently being used widely in industry to remove acid gas such as carbon dioxide.
Membrane is one of the technologies that currently ongoing rapid research &
development to cater the problem of carbon dioxide that recently keep on increasing in
gas field.
The performance of membrane is depending on two factors that are membrane material
and processing condition. To achieve better flux, correct membrane material as well as
correct processing condition is needed. Therefore, the effect of various operating
condition to the performance of membrane is investigated. The performance of
membrane is evaluated based on observing the effect of various operating condition
such as feed temperature, feed pressure and permeate pressure to the permeation rate of
carbon dioxide.
The scope of study revolves around adjusting differences operating condition such as
feed temperature, feed pressure as well as permeate pressure and see the effect to the
permeation rate of carbon dioxide. The study is carried out by using simulation software
available called HYSYS simulator and incorporated with visual basic for calculation
part. The process flow diagram that consists of flow stream, compressor, heater and
membrane is built. Then, simulation start with allowing carbon dioxide to flow through
these components until they reach membrane where from there, carbon dioxide is
permeated through permeate channel. After running the simulation, the result that
obtained is analyzed and discussed.
It was found that the effect of various operating condition such as feed temperature,
feed pressure and permeate pressure give significantly impact to the performance of
membrane in terms of permeation rate of carbon dioxide. Therefore, we need to take a
consideration regarding operating condition when come to design or optimize the
performance of membrane.
