Biogas up-grading treatments aimed at producing biomethane to fuel vehicles or to inject into the gas grid, are applications that are gaining increasing interest throughout Europe. Several different commercial methods are available for separating carbon dioxide from biogas. In this work two innovative carbon dioxide removal methods that, differently from the currently employed commercial techniques, allow also to capture and store the separated carbon dioxide are investigated. The first investigated process, named alkali Absorption with...
