    摘要: Apparatus and methods for reducing residual solvent levels in extracted biomass that is contaminated with HFC solvent that includes sparging the biomass extract with a solvent stripping gas such as air or nitrogen are disclosed. Apparatus for carrying out the method include a vessel (12;25) containing extract (26) and a source of the gas. The source may be in the form of a moveable, hollow wand (27) having a sparging gas outlet; or a fixed gas inlet (30) for bubbling the gas through the extract (26).

    摘要: An apparatus (10′) for extracting biomass includes an extractor (11), evaporator (12), compressor (13) and condenser (14) connected in series by pipework (17) to define a closed loop extraction circuit. A transfer line (18) selectively supplies hot solvent vapor from the outlet side of the compressor (13) to the interior of the extractor (11), where the solvent vapor heats the biomass. This causes stripping of solvent from the biomass. The transfer line (18) includes control elements (19,20) for controlling the flow of solvent vapor.

    摘要: A slip-form of the kind for defining at least one surface of a wall-space into which concrete is to be poured. The slip-form includes a plurality of spaced apart upwardly extending members and to facilitate the locating of reinforcing rods at selected positions in the wall-space the slip-form includes roller assemblies releasably engaged with at least some of the support members to form within the wall space a height adjustable horizontal race and an inclined race feeding down to said horizontal race. The inclined race being adapted to transport reinforcing rods onto the horizontal race for onward transport to a location adjacent the selected position in the reinforcing structure.
