Open the CIPO recordAbstract From the Canadian patent
Method and apparatus for enhancing the combustion of a process gas of variable composition which gas is used for steam generation in producing heavy oil. The mass flow of the process gas containing hydrocarbons carbon dioxide and water is measured. It is assumed that the process gas is saturated with water vapor and the water content of the process gas is then obtained. The content of carbon dioxide in the process gas is nominally obtained with an oxygen analyser measuring the flue gas from a steam generator thereby giving a close approximation of hydrocarbon content and allowing an expedited calculation of the energy content and air required. The nominal carbon dioxide value is compared …

Why it's free to use
- Filed June 10, 2004 and granted July 3, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 10, 2024.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 10, 2026.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
