Process And Configuration For Providing External Upflow/Internal Downflow In A Continuous Digester

View page
US Patent:
20020129911, Sep 19, 2002
Filed:
Oct 16, 2001
Appl. No.:
09/978899
Inventors:
Bruno Marcoccia - Peachtree City GA, US
James Prough - Saratoga NY, US
Louis Torregrossa - Queensbury NY, US
International Classification:
D21C007/14
D21C007/00
US Classification:
162/041000, 162/043000, 162/241000
Abstract:
A continuous digester configuration and process for continuously cooking and digesting cellulosic material and producing cellulosic pulp is disclosed. The digester configuration comprises a plurality of jump-stage recirculations located along the length of a continuous digester vessel, wherein each of the jump-stage recirculations moves extracted liquor from one elevation of the digester vessel and re-introduces the liquor at a higher elevation in the vessel to maintain an internal liquor downflow substantially throughout the entire digester vessel. The process for continuously cooking and digesting cellulosic material comprises maintaining an internal concurrent liquor downflow substantially throughout the continuous digester vessel, wherein the internal liquor downflow does not exceed 400 gallons per ton of b.d. wood feed.

System And Method For Improving The Movement And Discharge Of Material From Vessels

US Patent:
20030111200, Jun 19, 2003
Filed:
Jul 16, 2002
Appl. No.:
10/042718
Inventors:
James Prough - Saratoga NY, US
Bruno Marcoccia - Peachtree City GA, US
Louis Torregrossa - Queensbury NY, US
International Classification:
D21C007/06
D21C007/08
US Classification:
162/233000, 162/237000, 162/246000, 008/156000, 422/129000, 068/18100R
Abstract:
Systems, methods, and vessels for reducing the stagnation and non-uniform flow or treatment of solid materials and slurries in vessels. The non-uniform flow or treatment that may characterize the storage or treatment of solid materials in process industries is minimized or eliminated by the introduction of liquid to the bottom heads of the vessels, in particular, the introduction of liquids in regions in the bottom heads where friction and compression cause stagnation in the flow of material. The liquid may be introduced by means of one or more nozzles, for example, one or more evenly-spaced nozzles, and the flow of liquid to each nozzle may be individually controlled. Though the systems, methods, and vessels disclosed may be used in the processing of cellulose materials, aspects of the present invention may be used in any process or materials handling industry application where solid materials or slurries are handled in vessels.

Bruno Marcoccia - Peachtree City GA, US
Louis Torregrossa - Queensbury NY, US
Assignee:
GLENS FALLS GROUP, LLC. - Queensbury NY

D21C007/08
D21C007/12
D21C007/14
US Classification:
162/039000, 162/052000, 162/049000, 162/061000, 162/062000, 162/238000

Method For Reducing Contamination In Pulp Processing

View page
US Patent:
49448420, Jul 31, 1990
Filed:
Mar 26, 1987
Appl. No.:
7/040245
Inventors:
C. Bertil Stromberg - Glens Falls NY
Joseph R. Phillips - Glens Falls NY
Louis O. Torregrossa - Glens Falls NY
Assignee:
Kamyr, Inc. - Glen Falls NY
International Classification:
D21C 902
D21C 910
D21F 166
US Classification:
162 60
Abstract:
Method and apparatus for reducing contamination in processed pulp and in white water effluent discharged from a pulp dryer or paper making mill. The system includes multiple pulp bleaching and washing stages wherein white water effluent discharge from the dryer or paper making mill is fed to the next-to-last washing stage and fresh water is supplied to the last washing stage.

Method Of Chemically Reacting A Slurry With A Gas

View page
US Patent:
54725674, Dec 5, 1995
Filed:
Dec 15, 1994
Appl. No.:
8/356455
Inventors:
Louis O. Torregrossa - Glens Falls NY
Assignee:
Kamyr, Inc. - Glens Falls NY
International Classification:
D21C 9153
D21C 1106
D21D 524
US Classification:
162 6
Abstract:
A number of different, efficient treatments of slurries and liquid with gas can be provided. A slurry or liquid is introduced into a first end of a vortex. A gas--such as a chemically reactive gas--is introduced from exteriorly of the vortex into contact with the slurry or liquid in the vortex, so that a desired reaction between the slurry or liquid and the gas takes place. The treated slurry or liquid is removed from the second end of the vortex while any residual or carrier gas is removed from the first end of the vortex. Gas introduction is preferably accomplished through a porous surface of revolution (e. g. cylindrical or conical) wall surrounding the vortex, the gas being in minute bubble form when it enters the slurry or liquid. This has particular applicability in the treatment of paper pulp using an ozone containing gas, or in reacting various liquids in the paper and pulp industry with gas (such as reaction of caustic solutions with chlorine or chlorine dioxide gas), the stripping of a strippable component from a liquid (e. g. stripping black liquor soap from black liquor, using air), or absorbing an absorbable component in a gas into a liquid (such as absorbing ozone, chlorine, or the like in water), or scrubbing furnace flue gases.

Bleaching Cellulose Pulp Having Cleanliness Which Varies Significantly Over Time Using At Least Two Different Bleaching Stages And Bleaching Chemicals

View page
US Patent:
61533009, Nov 28, 2000
Filed:
Apr 18, 1994
Appl. No.:
8/229086
Inventors:
C. Bertil Stromberg - Glens Falls NY
Patrick E. Sharpe - Queensbury NY
Louis O. Torregrossa - Queensbury NY
Joseph R. Phillips - Queensbury NY
Assignee:
Ahlstrom Machinery, Inc. - Glens Falls NY
International Classification:
D02G 300
US Classification:
428393
Abstract:
Recycled paper pulp having at least two different types of paper which consume widely different amounts of bleaching chemical, or mixed hardwood and soft-wood pulps, are treated in a manner that enhances distribution and redistribution of bleaching chemical to enhance uniformity of the bleaching treatment. The pulp is intensely mixed to provide a homogenous mixture of fibrous material and bleaching chemical, and then is continuously or intermittently subjected to mechanical action (such as in low intensity mixers, or by agitating pulp in a retention tank) of sufficient intensity and duration so as to enhance distribution and redistribution of a bleaching chemical. Also, recycled pulp will have cleanliness which varies significantly over time, and this is accommodated by sensing at least one of the brightness, color, or lignin content (e. g. all three) of the pulp prior to treatment in a first bleaching stage, controlling the quantity of first bleaching chemical added to the first stage in response to at least one of the brightness, color, or lignin content sensing to achieve a target brightness increase for the first stage, and then repeating the sensing and quantity control steps for a second and subsequent stages. Alternatively all sensing can be done initially.

Acid Pre-Hydrolysis Reactor System

View page
US Patent:
53383664, Aug 16, 1994
Filed:
Jan 4, 1993
Appl. No.:
7/997711
Inventors:
Todd S. Grace - Glens Falls NY
Mark D. Barrett - Glens Falls NY
Vic L. Bilodeau - Glens Falls NY
Gary L. McCarty - Glens Falls NY
Brian F. Greenwood - Glens Falls NY
J. Robert Prough - Glens Falls NY
Louis O. Torregrossa - Glens Falls NY
Assignee:
Kamyr, Inc. - Glens Falls NY
International Classification:
C13D 114
D21B 112
US Classification:
127 37
Abstract:
Biomass, such as bagasse, is pre-hydrolyzed, to ultimately effect hydrolysis of hemicellulose to sugars. Biomass is mixed with a mineral acid solution to form a slurry having a consistency of about 8 to 12% so that the acid solution properly wets the biomass. Then the slurry is dewatered to about 35 to 50% consistency, and is heated to reaction temperature (e. g. about 320. degree. F. ) by direct contact with steam in the vapor phase of a vertical pressurized reactor, having a pressure of about 40 psig. A fluffer is preferably provided in the top of the reaction vessel. After a reaction time of about 30 minutes, the biomass is diluted and cold blown out of the bottom of the reactor. Pressate from the dewatering has acid added to it and is heated by indirect heat exchange with a sugar solution obtained by washing of the biomass discharged from the reactor, and is then mixed with the biomass as the acid solution.
