PROCESS TECHNOLOGIES
Established solutions for renewables natural gas and alternative fuels
TerraVest offers only commercially proven gas processing technologies and systems to ensure project success
Biogas upgrading to produce high-quality renewable natural gas
Remove impurities from raw biogas to produce RNG for pipeline injection or fuel for compressed natural gas vehicles. Technologies offered:
-
- Pressure Swing Adsorption (PSA) – Adsorbing media attracts or adsorbs impurities under high pressure
- Membranes – Polymeric membranes separate impurities
- Water Wash – Highly pressurized water scrubs and absorbs impurities
- Amine – Scrubbing solvent adsorbs impurities that are later desorbed through heating

Gas recovery systems for alternative fuels

Maximize production opportunities for low-carbon fuels to reduce waste and costs. Solutions we offer include:
-
- Nitrogen – Present as an impurity in natural gas, nitrogen can be recovered for other uses
- Hydrogen – Recover and purify from hydrogen-rich streams for onsite re-use or in hydrogen fuel cells
- Syngas – Convert carbon rich waste to renewable power for onsite use
