Questor Technology Inc is a Calgary-based clean technology company specializing in the design, manufacture and deployment of membrane-based gas separation and upgrading systems. The company’s proprietary technology platforms are engineered to treat a wide range of industrial gas streams, including biogas from landfills and anaerobic digesters, CO₂-rich flue gases from power plants and hydrogen-containing streams from refineries. By combining polymer-based membrane modules with advanced process controls, Questor’s solutions enable efficient removal of contaminants, selective recovery of valuable gas components and compliance with stringent emissions standards.
The company’s product offerings are tailored for multiple industries, including waste management, agriculture, oil and gas, and power generation. Questor provides turnkey skid-mounted units that can be integrated into existing facilities or deployed as standalone systems. Typical applications include upgrading raw biogas into pipeline-grade renewable natural gas, removing CO₂ and other impurities from industrial off-gas streams, and recovering hydrogen for reuse in refining and petrochemical processes. Questor’s modular approach allows for rapid on-site installation, scalability and remote monitoring capabilities.
