Vaporless Chemical Transfer and Distillation

       Disclosed is an equipment arrangement comprised of a
Vaporless Distillation System and Vaporless Chemical Transfer Unit.
Both devices service nonflammable solvents, such as FREON* or methyl
chloroform, and are mobile.

      The transfer unit can be coupled to the distillation system or
used independently.  The distillation unit can operate from any type
container which can dispense the chemical via the self priming pump
mounted on the distillation unit.

      The vaporless design of the distillation unit is facilitated by
quick-disconnect fluid hoses from the supply container and reverse
venting from the distilled container back to the boiling vapor zone
of the distillation unit.  The vaporless design of the chemical
transfer unit is facilitated by quick-disconnect fluid hoses and
closed venting between the container receiving the fluid and the
container dispensing the fluid.

      The Vaporless Distillation Unit has the following components:
a.  Standard industrial distillation unit for boiling and condensing
nonflammable solvents.
b.  Self priming pump to the supply and upper and lower liquid level
controls for automatic pump operation.
c.  Closed take-up container for distilled solvent which is vented
back to the vapor zone of the distillation unit.
d.  Vertical pipe in the supply container positioned in a stationary
position approximately one inch from the bottom or a gravity flow to
the disti...
