Competitive Adsorption Study on Natural Gas Purification of Small-Scale LNG Project

The concept of modularized pretreatment of competitive adsorption was brought forward. The purification experiment measured the breaking through curves of natural gas in the compound adsorption columns of zeolite 3A and 13X molecular sieves, according to the proposed queue of adsorption modules. The experimental and simulative results indicate that the modularized competitive adsorption method of natural gas purification is feasible and effective for the small-scale LNG project.
