Abstract

Natural gas (NG) is the most important energy source in various sectors and industries not only for power generation, but also as a primary feedstock for chemicals, plastics and fertilizers. Due to high demand of natural gas as an energy source, the explorations of natural gas that contain more than 30 percent of CO2 become necessary. As C02 has been the major global warming contributor to the earth which also degrades the quality of natural gas and causing corrosion in refinery, this project aims to propose a new absorption system that uses methyethanolamine (MEA) to pre-treat at the source and lower the CO2 content before it enters the refinery. CO2 is treated with MEA along the height of contactor vessel and the absorption rate is measured at temperature of 30°C with the pressure range from 1 to 80 atm. This new absorption system is developed to remove 6 to 10 percentofCO2 from natural gas stream i.e. the CO2 content is reduced to 20%before transporting the natural gas to the aminetreating unit. The work investigates the effect ofoperationpressure and gas and solventvelocitieson CO2 concentration. The pressures used are 1, 10, 50 and 80atm and the velocity of gas are 6 and 28m/s with solvent superficial velocity of 0.016 and 0.055m/s. Studies shows that with the increase in operation pressure and solvent velocity directly increases the CO2 removal efficiency. Thisworkintroduces a feasible integration ofan absorption system to remove C02 at the NG reserves.
