Abstract
Abstract Distillation apparatus for steam distilling of solvents is disclosed in combination with phase separation means which is readily adjustable to accommodate fluids which are either more dense or less dense than water. This is accomplished in the preferred embodiment by attaching a pipe to an appropriate opening in the phase separation means. This permits a readily changed operation from one solvent to another and permits standardization of manufacture to accommodate essentially all water immiscible solvents.

Claim 3
Dependent Claim
172 words
a tank which has an inlet, a first outlet opening in the upper portion of said tank, a second outlet opening higher than said first outlet opening, and a third outlet opening higher than said second outlet opening, and 2. a coalescer within said tank and connected to said inlet whereby all of the liquids flowing into said tank are forced to pass through said coalescer. c. first means for alternately permitting said first outlet opening to be connected to a plug means or for permitting said fist outlet opening to be connected to a tube extending to a point near the bottom of said tank; and d. second means for alternately permitting said second outlet opening to be opened to a point near the upper portion of said tank or for permitting said second outlet opening to be connected to a tube extending within said tank to a point near the bottom of said tank, while said second means is open to a point near the upper portion of said tank.
Claim 4
Dependent Claim
172 words
a tank which has an inlet, a first outlet opening in the upper portion of said tank, a second outlet opening higher than said first outlet opening, and a third outlet opening higher than said second outlet opening, and 2. a coalescer within said tank and connected to said inlet whereby all of the liquids flowing into said tank are forced to pass through said coalescer. c. first means for alternately permitting said first outlet opening to be connected to a plug means or for permitting said fist outlet opening to be connected to a tube extending to a point near the bottom of said tank; and d. second means for alternately permitting said second outlet opening to be opened to a point near the upper portion of said tank or for permitting said second outlet opening to be connected to a tube extending within said tank to a point near the bottom of said tank, while said second means is open to a point near the upper portion of said tank.
Claim 5
Dependent Claim
