Description

Известный способ декальцинации рапы, содержащей соли кальци  i; магни , с применением осадител  малоэффективен, так как св зан с. большими потер ми магни , не обеспечивает глубокой очистки рассола от кальци  и серы и дает трудно фильтрующиес  и отмывающиес  осадки.A known method for decalcification of brine containing calcium salts i; magnesium, with the use of precipitator ineffective, as associated with. large losses of magnesium, does not provide deep purification of the brine from calcium and sulfur and gives difficult to filter and washable sediments.

Описываемый способ декальцинации рапы в отличпе от известного устран ет отмеченные недостатки и ускор ет процесс декальцинацпи. Это достигают тем, что в качестве осадител  кальци  примен ют сульфит натри  с добавкой глицерина.The described method of decalcification of brine, in contrast to the known method, eliminates the noted drawbacks and speeds up the process of decalcine. This is achieved by using sodium sulfite with the addition of glycerol as a calcium precipitant.

Способ осуществл ют следующим путем. Природный рассол (рану), содержащий 1 г/л кальци  и более, обрабатывают при перемещиванн и температуре 70-80° раствором технического сульфита натри , который берут с избытком относительно кальци  на 25-50%. К рабочему раствору , содержащему сульфита натри  150-200 г/л, добавл ют глицери в количестве 1 : 20000. После 40 мин. перемещивапи  и 15 мин. отсто  осветленный раствор отфильтровывают через контрольный фильтр от быстро оседающих кристаллов сульфита кальци . В этих кристаллах отнощенне магни  к кальцию не превыщает 2-3%, т. е. потери магни  рапы при декальцинации незначительны. При многотоннажном производстве дл  утилизации сульфита кальци  целесообразна его прокалка с получением технического алебастра.The method is carried out in the following way. A natural brine (wound) containing 1 g / l of calcium and more is treated at a temperature of 70-80 ° with a solution of technical sodium sulfite, which is taken with an excess of calcium relative to 25-50%. Glyceride in the amount of 1: 20000 is added to the working solution containing sodium sulfite 150-200 g / l. After 40 minutes. move and 15 min. After this, the clarified solution is filtered through a control filter from rapidly precipitating calcium sulfite crystals. In these crystals, the ratio of magnesium to calcium does not exceed 2–3%, that is, the loss of magnesium during decalcification is insignificant. In the case of large-scale production for the disposal of calcium sulfite, it is advisable to calcine it to produce technical alabaster.

Дл  получени  карбопата магни  (окиси магни ) рсактпвиоГ квалификации без кальци  и серы из декальцинированной рапы поступают следующим образом. Окисл ют декальцинированпую рапу гипохлоригом натри , содержащего 60-70 г/л активного хлора и 2-3 г/л свободной щелочи из расчета окислени  остаточного сульфита в сульфат, окислени  и осаждени  примесей марганца и железа, осадки которых отфильтровывают . Маточный раствор обрабатывают при перемеппшании и темпераTo obtain magnesium (magnesium oxide) carbopate, garnet calcium without sulfur and sulfur qualification from decalcified brine is obtained as follows. Decalcified brine is acidified with sodium hypochlorite containing 60-70 g / l of active chlorine and 2-3 g / l of free alkali based on the oxidation of residual sulfite to sulfate, oxidation and precipitation of impurities of manganese and iron, the precipitates of which are filtered. The mother liquor is treated with stirring and tempera
