The fore-mentioned studies for DME from biogas and black liquor
have limited scope (i.e., not including biogas generation from organic waste) or have inconsistent functional unit (i.e., per plant).
Weak black liquor
leaving the brown stock washers contains 13 to 17% dissolved solids.
A number of paper companies producing and burning black liquor
took this opportunity to repay a portion of the AFMC refund and file for the CBPC.
Consideration of biogenic C flows.--In the LCI, biogenic C flows, including the C[O.sub.2] uptake from the atmosphere during plant growth and the C[O.sub.2] release to the atmosphere from bark and black liquor
combustion in the mill's CHP plant, were accounted for.
The contract has been signed to provide an integrated offering of Chemrec plants on a global lump-sum turn-key basis, and to co-market the Chemrec black liquor
gasification technology, a route to second generation biofuels or green power.
Typical applications are bleaching, digesters, pulp machines and black liquor
Liquefied natural gas: The package resurrects for one year a 50 cents per gallon tax credit for companies which use liquefied natural gas, liquefied coal and other alternative fuels, excluding ethanol, methanol and so-called "black liquor
" produced from paper manufacturing.
In neighbouring Nordic country Sweden, more innovations are emerging such as the technology to convert black liquor
from pulp and paper milling into dimethyl ether (DME).
Sixteen chapters discuss wood handling, the chemistry and technology of pulping and bleaching, recovery processes (including treatment of black liquor
and white liquor preparation), paper recycling processes, the structure and properties of wood polymers and pulps in the process line, equipment, pulp characterization, and end-product requirements.
While black liquor
is generally seen as meeting U.S.
"Biomass waste" includes municipal solid waste from biogenic sources, landfill gas, sludge waste, agricultural crop byproducts, straw, and other biomass solids, liquids, and gases; but excludes wood and wood-derived fuels (including black liquor
), biofuels feedstock, biodiesel, and fuel ethanol.
It will enable the concentration of black liquor
, a by-product from pulp and paper production, so that it can be further re-used as fuel in the plant.
