| الوصف: | Simulations of enhanced coalbed methane recovery (CBM) and CO2 sequestration in coalbeds require an adsorption model to predict the amount of adsorbed gas in a reservoir as a function of pressure, temperature, and gas composition. The availability of a coal-structure-based generalized adsorption model would be a valuable tool for use in a reservoir simulator, since it would facilitate predictions of gas adsorption behavior at the conditions encountered in CBM production and CO2 sequestration. Therefore, in this work, we present a coal-structure-based generalized adsorption model capable of accurate a priori predictions of gas adsorption on diverse coals. The model was developed within a rigorous theoretical framework based on a local-density formulation. Specifically, we have utilized the simplified local-density/Peng−Robinson (SLD-PR) model and generalized it in terms of coal characterization information available from ultimate and proximate analyses of the coals. The newly developed generalized model is... |
