Description
Предлагаемый метод очистки природных рассолов вл етс комбинацией р да реакций, примен емых дл очистки расСОЛОВ .The proposed method for the purification of natural brines is a combination of a series of reactions used for the purification of SOLS.
Очистку предлагаетс проводить по следующей схеме. Рассол морского типа обрабатываетс хлористым кальцием, причем ион св занный с магнием в виде MgSOi выпадает в твердую фазу по реакцииCleaning is proposed as follows. Marine type brine is treated with calcium chloride, and the ion associated with magnesium in the form of MgSOi precipitates into the solid phase by the reaction
MgSO, + CaCi2 Mga2 + CaSO4 (1)MgSO + CaCi2 Mga2 + CaSO4 (1)
Сернокислый кальций выпадает в твердую фазу благодар насыщению им рассола до очистки.Calcium sulphate falls into the solid phase due to saturation of the brine with it before purification.
Освобождение от иона кальци , св занного с , осуществл етс добавкой в рассол после его фильтрации гидрата окиси магни или гидрата окиси кальци и последующей карбонизации по реакцииThe release of calcium ion bound to is accomplished by adding magnesium oxide hydrate or calcium oxide hydrate to the brine after filtering it and then carbonizing it by reaction.
CaS04 + Mg(OH)2 + СОз Мд5О44-Н20 + СаСОз(2)CaS04 + Mg (OH) 2 + COz MD5O44-H2O + CaCO3 (2)
Выпавщий СаСОз отдел етс от рассола , после чего последний, содержащий незначительные количества MgSO4, за счет реакции (2), подвергаетс выпарке с целью получени поваренной соли. Выпарка ведетс до начала выпадени MgSO4 (ничтожное содержание MgSO4 позвол ет вести выпарку почти до полного извлечени поваренной соли).The precipitated CaCO3 is separated from the brine, after which the latter, containing insignificant amounts of MgSO4, is subjected to evaporation due to reaction (2) in order to produce salt. The residue is maintained before the start of the precipitation of MgSO4 (a negligible MgSO4 content allows evaporation almost to the complete extraction of table salt).
Маточные рассолы, содержащие в основном MgClj, могут подвергатьс очистке от иона SO по реакции (1) указанна очистка осуществл етс во избежание загр знени Мд(ОН)2 по реакции (3).Master brines containing mainly MgClj can be purified from SO ion by reaction (1). This purification is carried out in order to avoid contamination of Mg (OH) 2 by reaction (3).
Освобожденный от иона фильтрованием выпавшего CaSO4 маточник подвергаетс обработке известью по реакции (3)The mother liquor freed from ionization by filtration of precipitated CaSO4 is subjected to lime treatment according to reaction (3)
MgCU + Ca(OH)2 CaCl2-fMg(OH)2 (3).MgCU + Ca (OH) 2 CaCl2-fMg (OH) 2 (3).
Полученный гидрат окиси магни отдел етс от раствора и направл етс на реакцию (2). Рассол хлористого кальци направл етс на реакцию (1).The resulting magnesium oxide hydrate is separated from the solution and sent to reaction (2). Calcium chloride brine is sent to reaction (1).
Значительный избыток маточных рассолов , содержащих хлористый магний, используетс либо дл получени выпаркой щестиводного хлористого магни , либо дл получени гидрата окиси магни , осаждением известью и твердого хлористого кальци упаркой рассолов.,A significant excess of uterine brines containing magnesium chloride is used either to produce shale-water magnesium chloride by evaporation, or to obtain magnesium oxide hydrate, to precipitate lime and solid calcium chloride by evaporation of brines.
Прилагаема схема иллюстрирует изложенный способ.The attached diagram illustrates the method outlined.

1. Способ получени из морских рассолов солей: сульфата и карбоната кальци , хлористого натри и щестиводного хлористого магни , а также гидроокиси магни , отличающийс тем, что рассол последовательно обрабатывают полученными в том же процессе хлористым кальцием и гидроокисью магни с промежуточным и последующим отделением выпадающих осадков и выпариванием фильтратов.1. A method of producing calcium sulfate and calcium carbonate, sodium chloride and magnesium phthalate, as well as magnesium hydroxide from sea brine salts, characterized in that the brine is sequentially treated with calcium chloride and magnesium hydroxide obtained in the same process with intermediate and subsequent separation of precipitates and evaporation of the filtrates.
