FLOW GOVERNOR AND LIMITER DISC ASSEMBLY IN AN EXTRACTION COLUMN

摘要

A flow limiter system is provided for extracting compounds from raw materials with an extraction column. The flow limiter system may include a flow governor assembly which contains and buffers a flow of pressurized solvent entering the base of the extraction column to prevent the flow of pressurized solvent from drilling into the raw materials packed within the extraction column. The flow governor assembly may further include a first disc with a first set of perforations to direct the surge of solvent through the first disc to transform the turbulent surge of solvent into a column of non-turbulent solvent with a flat surface layer that rises up the extraction column evenly and collectively. Additionally, the flow limiter system may also include a limiter disc including a second set of perforations to allow the extracted effluent to flow through the set of perforations and exit the extraction column.

主权项

1. A flow governor assembly comprising:
a first disc that contains and buffers a flow of pressurized solvent entering a base of the extraction column to prevent the flow of pressurized solvent that is turbulent from drilling into the raw materials packed within the extraction column;
wherein the first disc comprises a first set of perforations allowing portions of the solvent to pass through the first disc causing the flow of solvent to be reconstructed into a non-turbulent surge-free well of solvent with a flat surface layer that evenly and collectively rises up the extraction column.
