The treating apparatus and method of the present invention improve the efficiency and reliability of flash treating crude oil by including a recycled oil pumping loop that takes hot crude oil from a flashing section of a vessel and feeds it to either the inlet of a treater section or through a heater into a connecting pipe between the treater section and the flashing section, thereby eliminating the need of a fired heater in the flashing section.

Why it's free to use
- Filed June 21, 1996 and granted January 9, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 21, 2016.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 21, 2018.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
