Integral Sweep Controller For Gas Membrane Separation Device
US Patent:
7938884, May 10, 2011
Filed:

Assignee:
SPX Corporation - Charlotte NC
International Classification:
B01D 53/22
US Classification:
95 45, 95 1, 95 52, 96 4, 96 8, 96 10, 96417, 210640, 55DIG 17
Abstract:
A method and apparatus are provided for controlling the amount of purging that occurs within a membrane separation device. The membrane separation device includes a membrane separation component and sweep controlling component. Within the membrane separation component, a major portion of the non-permeate gas is sent out of the membrane separation device to work, while a minor portion is diverted for use as a sweep gas. The sweep gas is controlled by a valve that cycles with a device, such as a compressor. Thus, the membrane separation device is on when the compressor is on and is off when the compressor is off. As such, the membrane separation device is not required to sweep at all times.
Variable Evaporator Control For A Gas Dryer
US Patent:
6711906, Mar 30, 2004
Filed:
Apr 16, 2002
Appl. No.:
10/123565
Inventors:
Brian W. Pritchard - McKees Rocks PA
Mark F. Honath - McKees Rocks PA
Timothy J. Fox - Waynesburg PA

Assignee:
Hankison International - Canonsburg PA
International Classification:
B01D 118
US Classification:
62 93, 62208
Abstract:
A variable evaporator control system and method in a gas dryer for maximizing the cooling which can be accomplished for a given length heat exchanger by adjusting the evaporator refrigerant approach temperature responsive to changes in the gas load on the system. Pressure and/or temperature sensors positioned at particular locations in the system provide feedback for controlling adjustments in the approach temperature depending on the gas load.
Membrane-Based Compressed Air Breathing System
US Patent:
7972415, Jul 5, 2011
Filed:
Dec 11, 2008
Appl. No.:
12/332709
Inventors:
Timothy J. Fox - Waynesburg PA, US

Mark F. Honath - McKees Rocks PA, US
Assignee:
SPX Corporation - Charlotte NC
International Classification:
B01D 53/22, A62B 7/10
US Classification:
95 45, 95 52, 95143, 95273, 96 4, 96 8, 96 10, 96111, 96417, 55315, 422 4, 422119, 422122, 423247, 12820512, 12820529
Abstract:
A breathing air purification device and method having a carbon-monoxide free sweep stream. Water vapor is removed from a compressed air stream using a membrane dryer, comprising, a membrane having a permeate portion and a non-permeate portion, a membrane housing which encases the membrane, a membrane feed inlet conduit connected to the membrane and a non-permeate gas outlet conduit fluidly connected to the non-permeate portion of the membrane. The sweep stream used to cleanse the outer permeate portion of the membrane dryer is taken from a catalyst filter. The catalyst filter includes a cartridge containing a bed of catalyst, two end pieces maintaining the cartridge within a catalyst bed housing and having outlet holes, a catalyst inlet conduit connected to the bed of catalyst and a product gas outlet conduit connected to the outlet holes. A sweep inlet tube provides a gas connection from the catalyst filter component to the permeate portion of the membrane.
