Abstract: A process for extracting a target compound from a biomass includes: extracting a compound from a biomass charge using supercritical or subcritical CO2 as a solvent, at a first pressure and a first temperature, to yield a compound-laden solvent stream, the compound-laden solvent stream including the solvent, a solubilized target compound, and a solubilized byproduct compound; changing the temperature while maintaining the first pressure of the compound-laden solvent stream to desolubilize the byproduct compound from the compound-laden solvent stream to yield a resultant stream containing the solvent, the solubilized target compound, and a desolubilized byproduct compound; passing the resultant stream through a filter medium to separate the desolubilized byproduct compound from the solubilized target compound; and collecting the solubilized target compound.

Abstract: A superheated steam generator for crude oil recovery systems includes a centrally disposed second stage electric superheated steam generating tank surrounded and fed by a plurality of radially spaced first stage electric steam generating tanks. A primary manifold system supplies water to each of the first stage tanks and includes a central reservoir communicating with a plurality of constriction fittings. Each constriction fitting includes a tapered nozzle directed interiorly of the manifold toward a removable plug closing an associated inspection orifice permitting cleaning of the manifold and removal of the associated constriction fitting. Tubes coupled to opposite external ends of the constriction fittings deliver water to the first stage tanks, and are coupled to elongated tubes having portions extending longitudinally interiorly of the first stage tanks.
