Filed:

Jun 17, 1996

Appl. No.:

8/664570

Inventors:

Richard John Kooy - Western Springs IL

Assignee:

Chicago Bridge & Iron Technical Services Company - Oak Brook IL

International Classification:

B65B 104

US Classification:

141 82

Abstract:

Apparatus for, and a method of, withdrawing liquefied cryogenic fuel stored in a primary insulated storage tank at a relatively low pressure and temperature; increasing the pressure of the withdrawn liquefied cryogenic fuel through a heat exchanger to warm the liquefied cryogenic fuel to a subcooled or near saturated liquid condition; and feeding the warmed and pressurized liquefied cryogenic fuel to an insulated tank on a vehicle at a refueling facility, said vehicle using liquefied cryogenic fuel as its fuel and the insulated vehicle fuel tank being adapted to safely contain and store the liquefied cryogenic fuel in liquid form, at an approximate saturated condition.

International Classification:

B65B 3100
F17C 904

US Classification:

141 11

Abstract:

Apparatus for, and a method of, withdrawing liquefied cryogenic fuel stored in a primary insulated storage tank at a low pressure and at a temperature close to its boiling point; increasing the pressure of the withdrawn liquefied cryogenic fuel and then feeding the pressurized liquefied cryogenic fuel through a heat exchanger to warm the liquefied cryogenic fuel to a subcooled or near saturated liquid condition; and feeding the said warmed and pressurized liquefied cryogenic fuel to an insulated tank on a vehicle at a refueling facility, the vehicle using liquefied cryogenic fuel as its fuel and the insulated vehicle fuel tank being adapted to safely contain and store the said liquefied cryogenic fuel in liquid form, at an approximate saturated condition.

US Patent:

45178062, May 21, 1985

Filed:

Apr 9, 1984

Appl. No.:

6/598494

Inventors:

Raymond Korzonas - Chicago IL

Assignee:

Chicago Bridge & Iron Company - Oak Brook IL

International Classification:

B01D 904

US Classification:

62123

Abstract:

Apparatus for separating ice from concentrated liquid and washing the ice, including a vessel having a bottom and vertical wall joined to the bottom; a plurality of vertical tubular members in the vessel extending upwardly from the bottom; perforations in the upper portion of the tubular members through which concentrated liquid in the vessel can drain into the tubes; a first conduit for feeding a slurry of ice and concentrated liquid to the vessel; a second conduit communicating with the tubes for withdrawing concentrated liquid from the tubes; a concentrated liquid withdrawal third conduit communicating with the vessel lower interior portion for withdrawing concentrated liquid from the vessel; and control means to maintain a predetermined concentrated liquid level, and a predetermined pressure distribution, in the vessel.

Appl. No.:

6/561891

Inventors:

John S. Andrepont - Lisle IL
Raymond Korzonas - Chicago IL

Assignee:

Chicago Bridge & Iron Company - Oak Brook IL

International Classification:

F17C 1300

US Classification:

62 54

Abstract:

A freeze concentrator of the shell and tube type containing a pool of liquid cryogen within the shell, the concentrator being adapted to maintain a constant temperature within the liquid cryogen. The temperature control comprises a flash tank located above the level of liquid cryogen within the concentrator, to which the vapors evolved from the boiling cryogen are passed. The flash tank is provided with a condenser for condensing the cryogen vapor which enters the flash tank, the resulting liquid cryogen collecting within the flash tank and being recycled therefrom by gravity to the pool of cryogen in the exchanger.
