Abstract:

The development and application of a novel non-polar oil recovery process utilizing a non-dispersive solvent extraction method to coalesce and recover oil from a bio-cellular aqueous slurry is described herein. The process could apply to recovery of algal oil from a lysed or non-lysed algae slurry, recovery of Omega fatty acids from a bio-cellular aqueous feed, recovery of Beta-carotene from a bio-cellular aqueous feed and for the removal from produced water in oil production and similar type applications. The technique of the present invention utilizes a microporous hollow fiber (MHF) membrane contactor. The non-polar oil recovery process described herein can be coupled to a collecting fluid (a non-polar solvent such as heptane, a biodiesel mixture or the previously extracted oil) that is circulated through the hollow fiber membrane. In cases where the biodiesel mixture or the previously extracted oil is used the solvent recovery step (e. g. distillation) can be eliminated.

Abstract:

Thermoelectric devices have an electrically conductive connector for connecting thermoelectric modules. The electrically conductive connector is a compliant mechanism having a first connecting region and a second connecting region that are rigid bodies and an elastically deformable region that is a flexible member positioned between the first and second connecting regions. The electrically conductive compliant mechanism connector enables facile manufacture and assembly of thermoelectric devices of various sizes and shapes that are conformable to irregularly shaped objects and body parts.
