Solubility of Carbon Dioxide (C02) From Natural Gas Using Various Types of Amine - Based Compounds

This final report emphasized on the project title "Selectivity of Carbon Dioxide ((: O, )
Removal in Natural Gas Using Various Type of Amine-Based Compound. It consist
multiple sections ranging from project background, literature review, methodology,
results and discussion and conclusion.
The objective of this project is to evaluate the solubility of carbon dioxide in various
amine compounds by performing laboratory experiments (batch process), using various
amine mixtures and ratios, manipulated system temperature and carbon dioxide partial
pressure. These amine-based compounds include secondary and tertiary amine mixtures,
where methyethanolamine (MDEA) is supported by a promoter or activator.
The equipment setup for the laboratory analysis involves High Pressure Gas Solubility
Cell (MODEL BP 22). This equipment has been designed for measurements of gas
solubility in liquid at high pressure and temperature. The unit is capable of determining
the solubility of gases in various liquid, effect of temperature and pressure on the
component solubility, formation of methane hydrate and other complexes under high
pressure and reduction of solubility after repeated solution stripping cycle. Also
included in this report are the experiment layouts and the calculations involved in
preparing the desired amine solutions.
