... working gas (H2) and cushion gas (CO2) also include: 1) competitive adsorption ( Chen et al. 2010 ); 2) inert gas stripping ( Shi and Durucan 2005 ), where the injection of the working gas lowers the partial pressure of the cushion gas and thus leads to the desorption of the cushion gas; 3) differential...

... is remarkablly affected by water chemistry and localized corrosion. The main influence factors of CO 2 corrosion include temperature, flow rate, ion concentration of medium, CO 2 partial pressure and water cut. [6] The effect of temperature on CO 2 corrosion is significant and complicated...

... pH reduction of the brine; therefore, we estimated the possibility of this microbial conversion process under high partial pressure of CO 2 in this study by investigating the following: – The habitations of above bacteria in a high/low CO 2 content reservoir – The pH reduction of brine...

... with the van’t Hoff equation: (3) K = K 0 exp ( − Δ H R T ) Firstly, the carbon dioxide adsorption isotherms are correlated as a function of carbon dioxide and nitrogen partial pressures for different temperatures. Then, the calculated coefficients for these equations...
