The balance is shown in Figure 23. Compactor Vendor Tests— Prior to pilot plant construction, hydropyrolysis char was not available in quantities sufficient for testing. The pilot plant compactor was designed assuming a feed similar to carbon black and included a feed screw with diminishing flights.

The method is for controlling a sodium and sulphur balance of a pulp mill while separating lignin from black liquor. Lignin is precipitated by using an acid followed by filtration. The lignin filter cake thus obtained is resuspended in acidic liquid and dewatered to form a second cake. The filtrate obtained after dewatering of the second cake is returned for washing and suspension of the ...

Black granite is a particular kind of commercial granite that when polished, is dark gray to black. It may be a diabase, diorite or gabbro. Geologists consider granite as any holocrystalline, (composed entirely of crystals large enough to see with the naked eye) (Figure 3) quartzbearing plutonic (cooled slowly in the Earth) igneous, rock.

called black liquor evaporation plant. Black liquor, which is a residual stream from the pulp production process, needs to be recycled for both environmental and economic reasons. In the liquor recovery cycle, the black liquor is concentrated in a multistage evaporation plant prior to combustion in a

In industrial chemistry, black liquor is the waste product from the kraft process when digesting pulpwood into paper pulp removing lignin, hemicelluloses and other extractives from the wood to free the cellulose fibers.. The equivalent material in the sulfite process is usually called brown liquor, but the terms red liquor, thick liquor and sulfite liquor are also used.

Recovery boiler is the part of Kraft process of pulping where chemicals for white liquor are recovered and reformed from black liquor, which contains lignin from previously processed wood. The black liquor is burned, generating heat, which is usually used in the process or in making electricity, much as in a conventional steam power plant.

A smallscale test program of 65% solids black liquor gasification was conducted in the benchscale molten salt gasifier. Nine tests were performed using both air and oxygen as the oxidant. The black liquor gasified readily and the product gas had a drybasis heating value of 70 Btu/scf with air and about 250 Btu/scf with oxygen.
