Abstract

A multi-pass distillation system has a boiling flask with a side exit portal which is functionally connected to a condenser, which is, in turn, functionally connected to one or more cold traps. The condenser condenses wet vapors into liquid while the cold traps protect a pump which is used to suction the air through the system from the boiling flask through the condenser and cold traps. In this manner, one can more accurately collect fractions by way of a sideways exit from the boiling flask, near the top of the flask, with a condenser extending into a body of the spherical flask, such as at a 45 degree angle.

Claims

1. A multi-pass distillation system comprising:

a boiling flask with a side exit portal with a most elongated length extending in a horizontal direction;

a first condenser attached to said side exit portal;

a plurality of cold traps and/or additional condensers functionally attached to one another and/or said first condenser;

wherein said first condenser extends into said side exit portal of said boiling flask.

2. The multi-pass distillation system of claim 1, wherein said first condenser extends into a spherical body of said boiling flask.

3. The multi-pass distillation system of claim 2, wherein an end of said first condenser which extends into said spherical body of said boiling flask is at a 45 degree angle and is situated directly above a heat source under said boiling flask.

4. The multi-pass distillation system of claim 1, wherein a most elongated length of said first condenser is in a horizontal direction and in line with said exit portal of said boiling flask.

5. The multi-pass distillation system of claim 4, wherein said plurality of cold traps and/or additional condensers comprises at least a first cold trap functionally connected to receive output of said first condenser, said first cold trap comprising coils extending in a vertical direction situated substantially above coils in said first condenser.

6. The multi-pass distillation system of claim 5, wherein said first cold trap has an entry portal extending into an exit portal of said first condenser.

7. The multi-pass distillation system of claim 6, wherein said first cold trap causes condensation of wet vapors and blow by vapors.

8. The multi-pass distillation system of claim 5, wherein said first cold trap has an exit portal connecting to a second cold trap of said plurality of cold traps, and said second cold trap of said plurality of cold traps has an exit portal extending into a third cold trap of said plurality of cold traps.

9. The multi-pass distillation system of claim 8, wherein said third cold trap has an exit portal which is above said second cold trap and said first cold trap through which a vacuum is pulled.

10. The multi-pass distillation system of claim 9, wherein said second cold trap has, on average, drier air pass through than said first cold strap and said third cold trap has, on average, drier air than said second cold trap.

11. The multi-pass distillation system of claim 8, wherein a vacuum sucks gas from said boiling flask towards said third cold trap.

12. The multi-pass distillation system of claim 11, wherein said gas passes substantially in a vertical direction upwards through said first, second, and third cold traps.

13. The multi-pass distillation system of claim 12, wherein said gas passes substantially in a vertical direction through said first, second, and third cold traps.

14. The multi-pass distillation system of claim 1, wherein said side exit portal is adjacent to a top edge of said boiling flask.

15. The multi-pass distillation system of claim 14, wherein said condenser has an intake opening which opens at a horizontal center of said boiling flask.

16. The multi-pass distillation system of claim 1, wherein vapors move vertically through said boiling flask and at least one cold trap of said plurality of cold traps and/or additional condensers, and said vapors move horizontally through connectors between any of said boiling flask, first condenser, and cold traps.

17. A method of using the multi-pass distillation system of claim 1, comprising the steps of:

distilling material through said first condenser;

distilling said material through at least one trap of said plurality of traps;

collecting said distilled material in part;

placing said part collected into said boiling flask a second time.
