CO2 Absorption Using Biogas Slurry: CO2 Absorption Enhancement Induced by Biomass Ash

Removal of H2S and CO2 from Biogas by Amine Absorption

Due to strategic and environmental reasons, currently, there is an increasing interest in biofuels as alternative energy source. Bio-alcohols and biodiesel are the alternatives been considered for auto-motion while biomass and biogas are the alternatives been considered for electrical power generation. Biogas is a medium-energy content fuel (~22 MJ/kg) derived from the organic material decompos...

Modeling and Simulation of CO2 Absorption Enhancement in Hollow-Fiber Membrane Contactors using CNT–Water-Based Nanofluids

Absorption of CO2 from a gas mixture containing CO2 and nitrogen by water-based CNT nanofluids in gas–liquid hollow fiber membrane contactor was modeled and solved using COMSOL Multiphysics 5.4. The model assumed partial wetting of the membrane, along with diffusion in the axial and radial directions. In addition, Brownian motion and grazing effects were both considered in the model. The main c...

Collision induced absorption in CO2 at 0.091 cm-1

2014 Collision induced microwave absorption has been studied at 0.091 cm-1 and 293 K up to 60 amagat density. Expressing the dielectric loss 03B5" in the form 03B5" = A03BD03C12(1 Bp), where 03BD is the frequency in cm-1 and p is the density, we find A = 0.22 10-7 (cm.amagat-2) and B = 0.008 2 (amagat-1). As a result the molecular quadrupole moment of CO2 is calculated to be 5.6 10-26 (esu). J....

Hyperbranched Polymers in Absorption: Experimental Co2 Solubilities

Oxidative coupling of methane (OCM) is an approach for the direct catalytic conversion of methane to higher hydrocarbons, which is currently being investigated at the Berlin Institute of Technology within the cluster of excellence UniCat (Unifying Concepts of Catalysis). Hereby, the conversion to ethylene is the major goal of the process. In the downstreaming process subsequent to the OCM react...
