Open the CIPO recordAbstract From the Canadian patent
The invention disclosed relates to a method and apparatus for separating a mixture containing an aqueous liquid and an immiscible organic phase. Such mixtures are separated into a substantially organic-free aqueous phase and a substantially aqueous-free organic phase. Productivity is enhanced by separating as a third product stream, a further organic phase containing only small amounts of an aqueous phase, which for some applications can usefully be combined with the substantially aqueous-free organic phase. Other means for enhancing productivity are also disclosed.

Why it's free to use
- Filed October 16, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended October 16, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 16, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
