Adsorption Research

Adsorption Research is an engineering firm that develops separation and purification processes based on adsorption, in which solid materials called adsorbents capture selected substances from a gas or liquid. Its main focus is removing carbon dioxide, nitrogen and oxygen from biogas so it can be used as renewable natural gas.

Its AdvanSorb systems purify renewable and conventional natural gas, using a modular design or one built to a project's needs. The firm also works on carbon dioxide capture, water purification, gas purification for electronics and industry, and air quality, and it offers research and development services. Its developments include a system that lets foundries recover and reuse the sulfur dioxide used in making cold box molds.
