Description
Известно, что сульфат в естественных услови х получаетс из мирабилита ;выветри1ванием.It is known that sulphate under natural conditions is obtained from mirabilite;
Целый р д предлагаемых ранее методов заводского обезвоживани Мирабилита в сульфат ие получил внедрени в промышленноот1и вследствие большого расх1ад.а топлива или применени дорогосто щих депидратирующих веществ (спирта, ацетона, эфира и т. д.).A whole series of previously proposed methods of plant dehydration of Mirabilit in sulphate has been implemented in industry due to the large amount of fuel consumed or the use of expensive depotrating agents (alcohol, acetone, ether, etc.).
Проводилс р ц работ по высаливанию с)льфата из расплавЛЭнного мирабилита твердой поваренной солью. Выход сульфата в некоторых случа х доходил до 88-90% по отношевию к. количеству сульфата натри , наход щемус в системе.Conducted salting works c) lfat from molten LIne mirabilite solid table salt. The yield of sulphate in some cases reached 88-90% in relation to the amount of sodium sulphate present in the system.
Однако получаемый сульфат «.атри сильно цементируетс всле/дствие образовани тенардиганой пл-анки и засор етс поваренной солью. Помимо того, расход хлористого иатри па 1 г сульфата составл ет свыше 900 кг.However, the resulting sodium sulfate is heavily cemented because of the formation of tenantedane pl-anka and clogged with common salt. In addition, the consumption of chloride and sodium per 1 g of sulfate is over 900 kg.
Все эти отрицательные влени не дают возможности воспользоватьс этими методами дл промышленных целей.All these negative phenomena make it impossible to use these methods for industrial purposes.
Предлагаетс способ получени -высококачественного кристаллического сульф-ата «атри из мирабилита.A method is proposed for producing a high-quality crystalline sulphate ata from mirabilite.
Пример. 200 (вес. ч. мирабилита плав т в своей кр стал.тлизационной воде 1и подогрев-ают до 80°. К расплавленному мирабилиту небольшими порци ми при непрерывном перемешивании в течение 45-60 минП|р1Иба1вл ют 100 вес. ч. насыщенного раствора поваренной соли, нагретого до той же температуры, после чего смесь охлаждают до 25°. Выпавший lOcaiyoK сульфата натри отдел ют от раствора на нутч-фильтре или центрифуге и выоушивают.Example. 200 (part by weight of mirabilite is melted in its crystalline water 1 and heated to 80 ° C. To molten mirabilite in small portions with continuous stirring for 45-60 minP | p1Iba1, 100 parts by weight of a saturated solution of boiling water salt, heated to the same temperature, after which the mixture is cooled to 25 ° C. The precipitated sodium sulfate lOcaiyoK is separated from the solution on a suction filter or centrifuge and dried.
Сульфат натри получаетс высокого качества, мелкокристаллический , не комкующийо , следующего среднего состава: сульфата натри 97%, повареиной соли 1,4%, воды 0,2% и нерастворимых 1,4%.Sodium sulfate is obtained from a high quality, fine crystalline, not lumpy, of the following average composition: sodium sulfate 97%, common salt 1.4%, water 0.2% and insoluble 1.4%.
Предлагаемый 1метод обезвоживани мирабилита в сульф-ат натри имеет особую ценность в услови х сол ных промыслов, где (в осенне-зим№ 82692- 2 НИИ период времени из рассолов выпадает большое количество мирабилита , который 1может быть дегидратирован в сульфат натри действием рапы ,непосредст1в е|Н1но из озер,а с небольшим добавлением к ней в зимнее врем поваренной соли до нужной канцектрации рассола, а в летнее времс -рапой из озера без добавлени повареннюй соли.The proposed method for the dehydration of mirabilite in sodium sulfate is of particular value under saltwater conditions where e | H1no from the lakes, and with a small addition to it in the winter of salt to the desired brine seam, and in the summer - from the lake without salt.
Предмет изобретени Subject invention
Способ получени сульф.ата натри из мирабилита при иизмих температурах действием поваренной соли, Отличаюш.ийс ITOM, что в качестве высаливаюнхего агеита примен ют непосредственио природную рапу СОЛЯ1НЫХ озер.The method of obtaining sodium sulphate from mirabilite at izmih temperatures by the action of salt, It is different from ITOM, that as a salting agent, it is used directly to the natural saltwater of the lakes.
