Regarding of many issues faced by the industrial process to remove C02. The writer
decides to come out with the latest innovation and technology that can overcome the problem.
The current technology is using chemical and physical solvent. The major drawback ofthe
traditional gas absorption separation is mainly causes by foaming issues, corrosion issues, effect
of impurities and concentration ofthe solvent. Several issues and challenges that in using current
C02 removal method is the intensive energy requirements, the corrosivity of the solvents, low
C02 loading capacity, hazardous to human health and environment, the degradation of amine,
and high cost to maintain the solvent. Therefore, new methodology or approach is needed to
overcome this problem. The objective of this research was to identify potential Ionic Liquid for
C02 adsorption and to investigate C02 adsorption process by selected Ionic Liquid. There are 3
types of ionic liquid that proved can absorb 0O2 which is l-K-butyl-3-mefhylimidazolium
tetrafluoroborate, [bmim]+[BF4]M-«-butyl-3-methylimidazohum dicyanamide and
[bmim]+pCA]'l-butyl-3-methylimidazolium acetate, [bmimf[acetatef. The criteria considered
to chose the ionic liquid is easy to synthesis, have a very low vapour pressure, minimal
degradation of ionic liquid, chemically stable, environmentally friendly, have distinct
selectivities and having carboxylate moiety bond. However the best among those 3ionic liquids
was chosen due to certain circumstances. In this research it involves several major activities, the
preparation of ionic liquid, characterization of ionic liquid, an absorption study on the ionic
liquid and result analysis on the ionic liquid. The study also involves a comparison with
monodiethanolamine,MEA which is the common chemical solvent that is being used in the
process plant The result from each solvent has been compared in the result analysis. The chosen
ionic liquid has proven can absorb C02 and can be further research for implementation in the
process industry.
