Molecular Sieve Depressurization Recovery System And Method
US Patent:
2012031, Dec 13, 2012
Filed:
Mar 28, 2012
Appl. No.:
13/432124
Inventors:
Daniel W. Sonnek - Lake Crystal MN, US
Gregory W. Loest - Utica SD, US
Gregory W. Loest - Utica SD, US
Assignee:
IntegroEnergy Group, Inc. - Utica SD
International Classification:
F17D 1/16
US Classification:
137 14
Abstract:
A method of depressurizing a molecular sieve used in ethanol production is provided. The ethanol production system includes a plurality of on-line molecular sieve bottles for removing water from ethanol production. When the molecular sieve bottle becomes saturated with water it is taken off-line to depressurize it. The depressurization and removal of water is done from the product discharge end resulting in an approximately 5% to 10% reduction in external energy required to run the ethanol production line.
Method Of Removing Heat During Ethanol Production
US Patent:
2012004, Mar 1, 2012
Filed:
Aug 26, 2011
Appl. No.:
13/219014
Inventors:
Daniel W. Sonnek - Lake Crystal MN, US
Gregory W. Loest - Utica SD, US
Gregory W. Loest - Utica SD, US
Assignee:
IntegroEnergy Group, Inc. - Utica SD
International Classification:
C07C 29/80, F28B 3/00
US Classification:
203 19
Abstract:
The present invention is directed towards a process of condensing ethanol during the distillation stage of ethanol production by using an air-cooled condenser. Typically ethanol producing facilities use water-cooled condensers to cool the vaporized ethanol into liquid ethanol. However this water-cooled condenser uses about 50% of the water used in the cooling tower and requires replacement. Due to growing concerns and scrutiny of water usage in the ethanol producing industry air-cooled condensers in the distillation step of ethanol production can significantly conserve water.
Multi-Stage Scrubbing System And Method For Ethanol Vent Streams
US Patent:
2011027, Nov 17, 2011
Filed:
Aug 27, 2010
Appl. No.:
12/870408
Inventors:
Daniel W. Sonnek - Lake Crystal MN, US
Gregory W. Loest - Utica SD, US
Gregory W. Loest - Utica SD, US
Assignee:
INTEGROENERGY GROUP, INC. - Utica SD
International Classification:
B01D 47/00
US Classification:
95199, 96228, 95223
Abstract:
A multi-stage scrubbing system comprises a pre-scrubber system structured to receive a vent stream therein and pre-scrub the vent stream with a pre-scrubber fluid. The pre-scrubber system includes a first outlet for discharging a pre-scrubbed vent stream and a second outlet for discharging a discharge stream of pre-scrubber fluid. A main scrubber system is fluidly coupled to the first outlet of the pre-scrubber system for receiving and further scrubbing the pre-scrubbed vent stream.
