Abstract: A porous cylindrical support for use in supporting a zeolite membrane has a generally cylindrical inside surface having a central axis extending in the longitudinal direction and a generally cylindrical outside surface that surrounds the inside surface. A zeolite membrane is formed on the outside surface. A maximum value A and a minimum value B of a support thickness in a circumferential direction satisfy (A?B)/(A+B)?0.3 in at least part of the support in the longitudinal direction, the support thickness being a radial distance between the inside surface and the outside surface. By reducing a variation in support thickness, it is possible to improve uniformity in the thickness of the zeolite membrane formed on the support.

Abstract: A high temperature paraffinic froth treatment (HTPFT) process utilizes an unheated flash vessel as a first stage of solvent recovery in a paraffinic solvent recovery unit (PSRU) to minimize asphaltene precipitation and fouling in subsequent stages of solvent recovery. The HTPFT may utilize a heat pump circuit for heat integration in the PSRU where a first stage of solvent recovery is at a lower temperature than a second stage of solvent recovery. Froth entering froth separation vessels can be heated using heat in a tailings stream using a heat pump. Froth separation vessels used to separate froth for collecting a bitumen-containing overflow utilize a collector pot and conventional feedwell combination, or a combination of a collection ring and nozzle arrangement for reducing disturbance in the vessel and improving collection of the overflow.
