The Cryogenic Carbon CaptureTM (CCC) process is a retrofit, post-combustion technology that desublimates CO2 in the flue gas, separates the resulting solid from the remaining light gases, pressurizes the solid CO2, melts the CO2 and warms the light gas, and completes the CO2 pressurization with liquid CO2. This skid-scale CCC system has demonstrated successful carbon capture of 90–99% from simu...

in this paper, an adaptive-network-based fuzzy inference system (anfis) is used for forecasting of natural gas consumption. it is clear that natural gas consumption prediction for future, surly can help statesmen to decide more certain. there are many variables which effect on gas consumption but two variables that named gross domestic product (gdp) and population, are selected as two input var...

We present an experimental investigation of Rayleigh-Bénard convection in binary-gas mixtures. In order to interpret the results quantitatively, we determined the necessary thermodynamic and transport properties for six mixtures ~He-CO2, He-SF6, He-Xe, Ne-Ar, Ar-CO2, and H2-Xe! by a combination of data from the literature, molecular-theory calculations, and thermal-conductivity measurements. Al...

Separation of CO2 from CO2-CH4 mixtures is an important issue in natural gas and biogas purification. The design of such separation processes depends on the knowledge of the behavior of multicomponent adsorption, particularly that of CO2-CH4 mixtures. In this study, we present a series of experimental binary equilibrium isotherms for CO2-CH4 mixtures on an activated carbon at 293 K and compare ...

carbon dioxide is a major greenhouse gas that contributes to the global warming by more than %60. absorption has been widely used to treat high concentrations of co2 in synthesis gas production, hydrogen manufacturing, and natural gas processing. the most well established method to capture co2 is its removal by absorption into amine solutions in the presence of activators. in this research, co2...

Title of Document: Efficiency Enhancement for Natural Gas Liquefaction with CO2 Capture and Sequestration through Cycles Innovation and Process Optimization Abdullah Alabdulkarem, Doctor of Philosophy, 2014 Directed By: Professor, Reinhard Radermacher, Mechanical Engineering Liquefied natural gas (LNG) plants are energy intensive. As a result, the power plants operating these LNG plants emit hi...

CO(2) sensing is of great societal implications, as CO(2) is a component of gas mixtures from many natural and anthropogenic processes with huge impacts on globe climate and human well-being. Herein we report a CO(2) assay scheme over a wide concentration range, utilizing a fluorogen with an aggregation-induced emission feature and a liquid with tunable polarity and viscosity. The CO(2) sensing...

Reducing CO2 in the atmosphere and preventing its release from point-source emitters, such as coal and natural gas-fired power plants, is a global challenge measured in gigatons. Capturing CO2 at this scale will require a portfolio of gas-separation technologies to be applied over a range of applications in which the gas mixtures and operating conditions will vary. Chemical scrubbing using abso...
