These two impurities reduce the heating value of NG. Also, CO2 causes corrosion in the pipeline and N2 produces nitrogen oxide (NOx) when combusted. These facts have forced NG transmission and distribution companies to limit the concentrations (mole percent) of CO2 (≤ 3%) and N2 (≤4%). Consequently, selective separation of CO2 and N2 from NG has gained considerable importance. There are many technologies that are in use for separation of these two constituents. Most of them are suitable for single component separation: either CO2 or N2. In the context of multicomponent separation common in industries, adsorption is an emerging technology that offers low-cost and energy-efficient separation for small- to medium-sized industries. The technology lacks commercial availability due to its dependency of design methodologies on experimentation, simulation or both. This work focuses on easy-to-use design methodology for the design of a double bed adsorber. This easy-to-use methodology is tailored for separation of CO2 and N2 from NG using zeolite13X and a carbon molecular sieve (CMS3K) or activated carbon (ACB). These adsorbents are commercially available, and they offer easy and energy efficient regeneration for repeated uses. The product will meet the specified concentration limit for NG transmission and distribution systems. To achieve this goal, two layered bed adsorbers, zeolite13X-CMS3K and zeolite13X-ACB, were simulated using Aspen Adsorption. Simulation requires a trustworthy mathematical framework i.e. model. Therefore, a model was developed in Aspen adsorption by selecting relevant equations and submodels.
