Gas Treatment

The way to excellence

Milestones of BASF’s Gas Treatment

The success story of gas treatment at BASF started decades ago. In 1971, the chemical company began removing carbon dioxide (CO2) from syngas for the production of ammonia, a crucial starting material for the manufacturing of fertilizers. One by one, the company developed also technologies for natural gas, refinery offgas, flue gas and biogas. At the same time, BASF continually expanded its portfolio.

First experiments by BASF chemist Wilhelm Wild (1872-1952) on water gas conversion in the context of ammonia synthesis.

1935: Alkazid Process

First application and licensing of the process known as BASF's alkazid process, which scrubs hydrogen sulfide and/or carbon dioxide off natural or synthetic gases.
