    Abstract: A process is described for the recovery of substantially pure ethyl acetate from a feedstock including ethyl acetate, ethanol and water. The process includes supplying the feedstock to a first distillation zone maintained under first distillation conditions effective for distilling from the feedstock a first distillate including ethyl acetate, ethanol, and less than about 10 mol % water. The first distillate is recovered from the first distillation zone and is supplied to a second distillation zone maintained under second distillation conditions, which include use of a higher pressure than that of the first distillation zone. The second distillation conditions are effective for distilling from the first distillate a second distillate including ethanol, water, and a minor proportion of ethyl acetate and yielding a substantially pure ethyl acetate bottom product, which is recovered. The second distillate is returned to the first distillation zone.

    Abstract: A method of loading a granulated solid into a vessel having a containment zone for the granulated solid. The method comprises providing in a bottom portion of the containment zone a first substantially vertical rigid columnar portion having a horizontal cross section large enough to accommodate an operative's body. Support means is associated with the substantially vertical rigid columnar portion. Granulated solid is charged into the containment zone under control of the operative so as to distribute granulated solid around the substantially vertical rigid columnar portion. A further substantially vertical rigid columnar portion having a similar horizontal cross section to that of the first columnar portion is positioned on top of the first columnar portion. These steps are repeated a sufficient number of times until the desired amount of granulated solid has been charged to the containment zone.
