Appl. No.:

5/705910

Inventors:

Richard Strauss - Lexington MA

Assignee:

Whatman Reeve Angel Limited - Maidstone

International Classification:

B01D 5314

US Classification:

55 31

Abstract:

A compressed gas dryer and a method of drying compressed gas, particularly air, which method comprises: intimately contacting a high-pressure, wet, compressed gas stream having a high relative humidity with a hygroscopic liquid absorbent miscible with the water to be removed, and separating the liquid absorbent and compressed gas to provide a wet liquid-absorbent mixture containing the water removed from the gas and a dry compressed gas stream; reducing the liquid-absorbent mixture to a lower pressure than the high pressure of the wet compressed gas stream; intimately contacting the liquid-absorbent mixture with a portion of the dry compressed gas stream at the lower pressure and separating the liquid absorbent from the gas stream to provide a dry liquid absorbent and a lower-pressure gas stream containing the water removed from the liquid-absorbent mixture; recycling the dry liquid absorbent for use in the contacting of the wet compressed gas stream; removing the wet lower pressure gas stream at the lower pressure; and purging the wet lower-pressure gas stream to the atmosphere.

International Classification:

B01D 2910

US Classification:

210232

Abstract:

An improved filter tube holder and a filter assembly in which such holder is used, which holder is adapted to secure a filter tube about a passageway in the mounting or sealing plate of the assembly, and which holder comprises: a closed end cap element disposed on one side of a mounting plate; a mounting bar strip element disposed on the opposite side of the mounting plate; first and second arched strip elements at one and the other end of a tie rod; a end cap element with an opening at the opposite end from the disc element on the one side of the mounting plate; the closed end cap element and the open end cap element adapted to secure in a sealing manner a filter tube therebetween, the tie rod adapted to pass through the passageway and the filter tube; means to secure the first and second strip elements to the tie rod; and a means to move the closed cap element and/or the mounting bar strip element toward each other to secure the filter tube therebetween in a fluid-tight manner about the passageway in the mounting plate.
