TPI technologies purify most CO2-containing streams coming from various sources.

1. Natural: Deep wells, natural gas
2. Chemical process waste streams: Ammonia synthesis, ethylene oxide, bioethanol, steam reforming
3. Combustion processes: Natural Gas, oil, coal, biomass, solid waste
4. Biological processes: Fermentation (bioethanol production), biogas off-gas, biogas digester (dairy farms), deep wells.

TPI plants are designed to produce high-purity CO2 (99,998%) from any source while meeting the most stringent quality requirements of the industrial gases industry and food and beverage industry in compliance with USDA, US FDA, Health Canada, COFEPRIS, CGA, EIGA, ISBT and/or other guidelines, standards and regulations around the world.
