- Zwart residuloog ontstaat wanneer papier wordt geproduceerd uit pulp. Als grondstof voor de pulp worden onder meer houtvezels gebruikt. Die kunnen op twee manieren worden verkregen: door het hout te malen (mechanisch proces) of door het te koken van ontschorst houthaksel (chemisch proces). Houtvezels bevatten evenwel lignine, de stof die papiervergeling veroorzaakt. Om de lignine uit de vezels te verwijderen, worden ze gekookt. Het resultaat daarvan, een bruinachtig deeg, wordt gewassen. Uit de kookvloeistof worden de chemicaliën gerecupereerd. Wat dan overblijft is zwarte residuloog. Die wordt gecondenseerd tot ca. 60% vaste stof, om als brandstof te worden gebruikt. IATE - by Max Nuijens

- "DME is bijzonder interessant omdat het zeer weinig gevolgen voor het klimaat heeft, wanneer je naar de volledige levensloop kijkt, van bron tot wiel," aldus Lars Mårtensson. "Het heeft de hoogste energiezuinigheid in vergelijking met andere alternatieven uit dezelfde grondstoffen. Bovendien is DME vanuit het kostenoogpunt al concurrerend als het wordt gemaakt van biomassa door middel van vergassing of van zwarte residuloog, afkomstig uit de pulpbranche." - Volvo

- Definition(s)
- Crni lug je otpadni proizvod sulfatnog (ili natron, kraft) postupka proizvodnje celuloze. Sadrži u vodi rastvoren lignin i hemiceluloze iz drveta, kao i neorganska jedinjenja korišćena u proizvodnom procesu. Own research - by V&M Stanković
- Example sentence(s)
- Posle kuvanja je odvajan crni lug i odredjene njegove fizičko-hemijske osobine, a sečka je mlevena u laboratorijskom PFI mlinu. - Institut za niz. šum. i živ. sredinu
by V&M Stanković - Pored ugljenik-disulfida, u „Viskozi“ ima i oko 100 tona sumporne kiseline, ali to će biti prodato u narednih desetak dana. Ima i nešto malo cink-sulfata, lagerovanog na sigurnom, a u „Celulozi“ ima oko dve tone furfurala, 1.400 kubnih metara retkog crnog luga, oko 750 kubnih metara belog luga i oko 400 kubika zelenog luga. To su nusproizvodi koje ne smemo da ispustimo, jer bi zagadili Drinu. - Blic
by V&M Stanković - - Korišćenje biomase
Pod korišćenjem drvne biomase podrazumeva se korišćenje drveta, drvenog uglja i crnog luga (black liquor-nusproizvod pri proizvodnji celuloze) - Rudarsko - geološki fakultet, Beograd

- Definition(s)
- Black liquor is a byproduct of the kraft process, (also known as kraft pulping or sulfate process) during the production of paper pulp. Wood is decomposed into cellulose fibers (from which paper is made), hemicellulose and lignin fragments. Black liquor is an aqueous solution of lignin residues, hemicellulose, and the inorganic chemicals used in the process. Wikipedia - by Enrique Cavalitto
- Example sentence(s)
- Black liquor (BL), a by-product of the chemical pulping process, is an important liquid fuel in the pulp and paper industry. It contains almost all of the inorganic cooking chemicals along with the lignin and other organic matter separated from the wood during pulping in the digester. - LULEÅ UNIVERSITETSBIBLIOTEK
by Enrique Cavalitto - Sometimes, people just need to make the best with what they have got to work with. This is what paper mills are trying to do by burning the "black liquor" waste which is a leftover remnant of chemicals and the lignin. As part of the Kraft process, the leftovers are burned to create steam which turns large generators, which in turn provide electricity for the plant. - AutoblogGreen
by Enrique Cavalitto - The black liquor waste stream is converted from the paper pulping process into synthesis gas. The synthesis gas can then be processed into a variety of fuels—likely dimethyl ether (DME) and methanol (MeOH), although fuels such as Fischer-Tropsch diesel (FTD), Synthetic Natural Gas (SNG), or hydrogen are also possible. - Conventus Communication AB

- Example sentence(s)
- Svartlut är en blandning av lignin, hemicellulosa och de kemikalier som finns i massakoket. - Ny teknik
