When it comes to biogas upgrading and recovering resources from biomass streams, there is no doubt that DMT should be your choice. Equipped with 30 years of experience we send our engineers worldwide to serve our customers and help them with their environmental challenges. The North American market is serviced from our office in Portland, (OR) and and branch office in Montreal Canada.
DMT has developed a vast amount of biogas treatment technologies; biogas upgrading, desulphurization and resource recovery. For the key biogas contaminants, DMT can offer one or a combination of technologies to economically manage them. A technology selection is made by analyzing the mixture of contaminants, the gas flow, the pollution load and the application. By not pushing one technology, DMT can provide the customer with the best solution for that specific project.
Our team of experts is dedicated to implementing renewable energy solutions today, ensuring a sustainable environment for our planet and future generations.
DMT is your industrial partner for gas desulfurization and conditioning, biogas upgrading, and CO₂ liquefaction.
