Making RNG from Biogas: Stories from Wärtsilä Puregas North America [ABC Sponsored Webinar]

November 19, 2020 @ 2:00 pm - 3:30 pm EST

Federal and state government incentives in the United States are driving biogas producers to consider upgrading their biogas. The uniqueness of each biogas project makes it a challenge to determine the best gas upgrading technology for the given situation. In this webinar, Wärtsilä experts explain the chemical absorption process and case studies from Wärtsilä Puregas’ 20 year history implementing these systems.
