Filed:

Sep 20, 1978

Appl. No.:

5/944116

Inventors:

David DiGregorio - Salt Lake City UT
Daniel McCarthy - Salt Lake City UT
Keith J. Mounteer - Salt Lake City UT
Charles D. Thompson - Hunter UT

Assignee:

Envirotech Corporation - Menlo Park CA

International Classification:

B01F 304
C02F 124

US Classification:

261111

Abstract:

A dissolving tank for dissolving a large amount of gas in a liquid and including a generally horizontally disposed tray (28) (29) mounted within the tank (2) (21) to divide the tank (2) (21) into an upper reaction zone (36) and a lower discharge zone (38). The tray (28) (29) has formed therein both a central opening (34) (35) for fluid communication between the discharge zone (38) and the reaction zone (36) and peripheral openings (32) (33) which allow any liquid which collects on the tray (28) (29) to flow from reaction zone (36) to discharge zone (38). The dissolving tank further includes liquid feed means (10) positioned within the tank (2) (21) below the tray (28) (29) to discharge liquid upwardly through the central opening (34) (35) of the tray (28) (29) and into the reaction zone (36). The dissolving tank further includes liquid distribution means (14) mounted within the tank (2) (21) above the tray (28) (29) and having flared sidewalls (15) and a vertically-oriented distribution orifice (16). The distribution means (14) is positioned so that a portion of the liquid discharged upwardly from the feed means (10) impacts on the flared sidewalls (15) and is distributed as droplets within the reaction zone (36) and another portion of the liquid discharged from the feed means (10) passes upwardly through the distribution orifice (16) toward the top (3) of the tank (2) (21).

International Classification:

C10L 5/44
C10L 5/36

Abstract:

A process for cleaning and beneficiating biomass is described which may allow removal of entrained salts and light volatiles from biomass materials. The process may also minimize energy use through capturing steam and flue gases for re-use. The process may generally comprise the following steps: prewashing and/or preheating a biomass, pressurizing the biomass in a steam explosion vessel, rapidly depressurizing the steam explosion vessel, releasing the steam from the steam explosion vessel entrained with fine lignin-enriched particles into a cyclone-type gas expansion vessel, routing the steam from the gas expansion vessel to the input hopper, subjecting the biomass to a second washing step, mechanically removing a portion of the water from the biomass, and evaporatively heating the biomass.

After the biomass has been steam-exploded, it may be washed and used as an engineered soil.
