- 黒液(こくえき、英語:Black liquor)は、木材パルプを作るときに化学的に分解・分離した際に発生する液体である。
紙の原料であるパルプは木材チップを薬品で煮溶かし(蒸解)、木材繊維(セルロース)を取り出す。その木材繊維を固めていたリグニン・樹脂成分と薬品が混じった液体を濃縮したものを黒液と呼ぶ。 Wikipedia - by Yasutomo Kanazawa
- Example sentence(s)
- 木材の50%は木材繊維で、残り成分50%の黒液は化石燃料の代替エネルギーとしても注目を集めている。 - Wikipedia by Yasutomo Kanazawa
- 黒液のカロリーは重油の1/2~1/3程度あり燃焼させる事が出来るため、回収ボイラーと呼ばれるボイラーで燃焼させて蒸気を発生させる。その蒸気でタービンを回し発電するが、圧力の下がった蒸気は抄紙工程に送られ紙の乾燥にも使われるため無駄なく効率的な利用が行われている。また燃焼させた後の灰を集めることにより、蒸解時に使った薬品も98%以上が回収され再利用される。 - Wikipedia by Yasutomo Kanazawa
- 日本で現在、最も有効利用されているバイオマスは、黒液といわれている木質系で、バイオマス利用全体の100%に近い約460万lk(原油換算)になる。黒液とは、パルプ工場でチップからパルプを製造するときに出る、樹液を含む廃液である。通常は、パルプ工場の燃料として使用され、向上で必要な全エネルギーのおよそ1/3をまかなうことができる。 - 日本総研 by Yasutomo Kanazawa

- 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 by Enrique Cavalitto
