Предложен безотходный процесс рециклинга отходов «мокрой» газоочистки, позволяющий получать фторалюминаты с криолитовым модулем не более 1,8–2,0. В процессе переработки растворов газоочистки оптимальное соотношение фторалюминиевой кислоты и фтори-да натрия составляет 14 : 9 (г/кгН2О), что обеспечивает наиболее полное связывание алюмофторидных ионов в продукты регенерации. Интервал pH &lt; 4 служит областью получения Na5Al3F14 (с примесью AlF3), при pH = 4÷6 происходит структурный переход от хиолита к криолиту Na3AlF6. Данный цикл предусматривает попутное получение сульфата алюминия и углеродистых концентратов, безотходную переработку фторидно-глиноземных шламов, а также использование диоксида углерода в процессах нейтрализации и очистки сточных вод. Рассчитаны оптимальные параметры, обеспечивающие снижение выбросов и улучшение баланса компонентов при внедрении «сухой» газоочистки в комбинированную (параллельную и последовательную) схему газоочистных и регенерационных сооружений.</p></abstract><trans-abstract xml:lang="en"><p>The paper demonstrates the possibility of increasing the efficiency of gas scrubbing systems in aluminum production by improving technologies for trapping and treatment of liquid and solid waste. The paper proposes a non-waste process of «wet» gas scrubbing waste recycling, which makes it possible to obtain fluoroaluminates with a cryolite module of no greater than 1,8–2,0. During treatment of gas scrubbing solutions the optimum ratio of fluoroaluminium acid to sodium fluoride is 14 : 9 (g/kgН2О), which ensures the most complete bonding of aluminum fluoride ions into regeneration products. The pH interval 5Al3F14 (admixed with AlF3), with structural transition from the chiolite to the cryolite Na3AlF6 occurring at pH = 4÷6. This cycle provides for the simultaneous production of aluminum sulfate and carbon concentrates, non-waste treatment of fluoride-alumina slurries, and the use of carbon dioxide in processes of neutralization and treatment of sewage. The paper calculates optimum parameters which ensure emission reduction and improve the balance of components when introducing the «dry» gas scrubbing into a combined (parallel and sequential) scheme of gas scrubbing and regeneration facilities.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>газоочистные и регенерационные технологии</kwd><kwd>электролиз</kwd><kwd>растворы и шламы газоочистки</kwd><kwd>глинозем</kwd><kwd>фторалюминаты</kwd><kwd>сульфаты</kwd><kwd>рециклинг отходов</kwd><kwd>сокращение выбросов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>gas scrubbing and regeneration technologies</kwd><kwd>electrolysis</kwd><kwd>solutions and slurries of gas scrubbing</kwd><kwd>alumina</kwd><kwd>fluoroaluminates</kwd><kwd>sulfates</kwd><kwd>waste recycling</kwd><kwd>emission reduction</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Гринберг И.С.
