Claims13
A flotation oil comprising:
- an intermediate stream obtained from an upgrader, a refinery, a slop, or slurry tank of gasoil and/or heavier streams,
- wherein the flotation oil comprises a polarized resin content, as measured by SARA (Determination of Saturates, Aromatics, Resins, and Asphaltenes (SARA) as measured by IP-469), of 2 wt. % to 25 wt. % and at least one of the following properties:
- a density at 15° C., as measured by ASTM-D4052, of 0.87 g/ml to 1.2 g/ml;
- and
- a flash point, as measured by ASTM D93, that is equal to or greater than 50° C.
