Absorption of Carbon Dioxide in a Bubble-Column Scrubber
In the current stage over 85% of world energy demand is supplied by fossil fuels. Coal-fired plants discharged roughly 40% of the total CO2 are the main contributors in CO2 emissions (Kim & Kim, 2004; Yang et al., 2008). Environmental issues caused by exhaust green house gases (GHG) and toxics have become global problems. Through the past studies of five decades, increased GHG levels in atmosph...
متن کاملModeling and Experimental Study of Carbon Dioxide Absorption in a Flat Sheet Membrane Contactor
comIn the present study, CO2 removal from natural gas stream has been studied using a flat sheet membrane contactor. A three dimensional mathematical model is developed to describe the process. The model considers the transport of a gas mixture containing carbon dioxide and methane through a flat sheet membrane contactor module. The model is based on the non-wetted mode of operation, in which t...
متن کاملAbsorption of Carbon dioxide in Packed Column
The absorption of carbon dioxide into aqueous ammonia solution using packed column was investigated. The volumetric overall mass transfer coefficients (KGav) for CO2 absorption into aqueous ammonia solutions were evaluated over ranges of main operating variables , that is, upto 16kPa partial pressure of CO2, 61-214 m 3 /(m 2 .h) gas flow rate, 0.753.06 m 3 /(m 2 .h) liquid flow rate, 2%16% ammo...

متن کاملMeasurement of Carbon Dioxide Column via Space Borne Laser Absorption
In order to better understand the budget of carbon dioxide in the Earth's atmosphere it is necessary to develop a global high precision understanding of the carbon dioxide column. In order to uncover the 'missing s ink that is responsible for the large discrepancies in the budget as we presently understand it calculation has indicated that measurement accuracy on the order of 1 ppm is necessary...
