Aliphatic amines are widely used as raw materials in much industrial process, and very
harmful chemical species constituting the focus ofmany environmental concerns. The
objectives ofthis project are to study the separation behavior of amine from natural
gas purification plant using membrane process, to investigate and study the factors that
affecting the performing of separation amine. Amine chose in this project is
Triethanolamine, TEA, which is a tertiary amine. In refinery gas treatment plant,
amine absorbed acid gas components, hydrogen sulfide, H2S and carbon dioxide, C02.
H2S and C02 are absorbed by the amine solution and the sweet gas leaves the
absorber. Once stripped of contaminants, amine solution is reused.
Asuggested method to study the separation ofamine is through membrane separation.
The factors affecting the membrane performance are operating pressure, feed
concentration, temperature, pH, concentration and cross flow velocity. Membrane
performance is analyzed based on the flux or rejection/ separation ofamine. Generally,
the separation of amine from wastewater using membrane system could be
implemented for industrial applications but with several modifications oftransport and
parameters that had to be studied further in order to achieve optimum results in the
industry application.
The effect of different parameters in membrane performance will be observed and
evaluated. The acquired results will be used for comparison of the importance of
experimental parameters in optimization of amines separation. The flux was increased
as operating pressure increased. Similarly, flux increased as velocity increased. CA202
has highest flux (104L/m2.h), followed by AFC40 and lowest was AFC99 (0.5L/m2.h).
From the analysis and feasibility study, the membrane separation process is a good
separation method in water treatment. AFC99 showed better result than AFC40 and
CA202. AFC99 almost removed 89%of amine, compared to AFC40, 69%and CA202
49%. Further analysis need to be done by using several methods, techniques and other
considerations should be taken in order to achieve the project objectives.
