Study the Performance of Nanozeolite NaA on CO2 Gas Uptake

Abstract

The adsorption isotherms and kinetic uptakes of CO2 were measured. Adsorption isotherms were measured at two temperatures 309 K and 333 K and over a pressure range of 1 to 7 bar. Experimental data of CO2 adsorption isotherms were modeled using Langmuir, Freundlich and Temkin. Based on coefficient of correlation it was found that Langmuir isotherm model was well suited with the experimental data of CO2 adsorption isotherms. In addition, Adsorption kinetic of CO2 mixture with N2 containing 10 % by volume CO2 and 90 % by volume N2 were determined in a temperature 36 °C and under the atmospheric pressure .When the flow rate was increased from 0.5 l/min to 2 l/min the time required for complete column saturation decreased. Also the effect of bed length on breakthrough curves was studied. The adsorption capacity increases by bed length increasing for adsorption of carbon dioxide.

Taguchi Design Methodology for the Optimization of CO2Permeance in Gas Capture Process from Polluted Air

“…These study's controlling variables are sweep flow rate, feed flow rate and feed pressure. For each factor, five levels were studied as shown in table (1).…”

“…Over the last few decades, climate change has been a major debate. An increase in CO 2 and other greenhouse gases is causes climate change (global warming) [1,2]. The major greenhouse gases are N 2 O ,CO 2 ,O 3 and CH 4 .…”

Carbon Dioxide Capturing via a Randomly Packed Bed Scrubber Using Primary and Poly Amine Absorbents

“…One of the most significant gases among GHGs is carbon dioxide [4]; the conventional carbon dioxide concentration in the stream of flue gases from different sources is listed in Table 1; carbon dioxide accounts for 76% of all GHGs globally [5]. The greenhouse gases absorb infrared light, which traps heat and causes the Earth's surface to warm; the term "greenhouse effect" refers to this phenomenon [6]; above this, in sour-gas production, the primary corrosion-causing species is carbon dioxide since the corrosion rate dramatically increases with the existence of carbon dioxide gas [7,8,9]. In order to control the environmental effects of greenhouse gas emissions and overcome the corrosion problems in downstream gas processing, it requires advancing effective technologies for carbon dioxide capturing produced by large stationary sources.…”
