Изобретение относитс к области очистки от мышь ка элементарной серы и может быть использовано на предгфи ти х, получаюП1их элементарную серу при комплексной переработке сульфидных руд, например медных.The invention relates to the field of purification of elemental sulfur from a mouse and can be used at pits, obtaining elemental sulfur in the complex processing of sulphide ores, for example, copper ores.
Известны способы очистки серы от неорганических примесей, в том числе от мышь ка. К ним относ тс способы химической и адсорбционной очистки серы.Methods are known for purifying sulfur from inorganic impurities, including arsenic. These include methods for chemical and adsorption purification of sulfur.
Способ химической очистки элементарной серы заключаетс в смешении ее в аппарате без давлени с сухой измельченной смесью окиси (или гидроокиси) щелочноземельного металла и карбоната или бикарбоната ш,елочного металла при одновременной или последуюш .ей обработке расплава перегретым паром в количестве не более 2% от веса серы {I.The method of chemical purification of elemental sulfur consists in mixing it in an apparatus without pressure with a dry crushed mixture of oxide (or hydroxide) of an alkaline earth metal and carbonate or bicarbonate, alkaline metal with simultaneous or subsequent treatment of the melt with superheated steam in an amount of not more than 2% by weight sulfur {I.
Наиболее близок к изобретению по технической сущности и достигаемому результату способ очистки серы от мыщь ка введением в серу сорбентов: активированного угл , активированной окиси алюмини , цеолита или их смеси нагреванием до 120-180°С при перемешивании с носледующим отделением адсорбента сразу или иосле растворени серы в сероуглероде или керосине III. Расходы сорбентов составл ют 100-200% от веса серы.Closest to the invention to the technical essence and the achieved result is the method of cleaning sulfur from the mouse by introducing into the sulfur sorbents: activated carbon, activated alumina, zeolite or their mixture by heating to 120-180 ° C with mixing with the next adsorbent separation immediately or after sulfur dissolution in carbon disulfide or kerosene III. Sorbent costs are 100–200% by weight of sulfur.
При исиользовании сорбентов дл очистки серы от мышь ка при непосредственном отделении сорбента выход очищенной серы составл ет 50-70%, а потери серы с сорбентом достигают 30-50%, что требует проведени специальной операции растворени серы в сероуглероде или керосине. Сравнительно невысокие содержани мышь ка в сорбенте после очистки (не более 0,15-0,30%) затрудн ют последующую утилизацию мышь ка.When sorbents are used to purify sulfur from arsenal with direct separation of the sorbent, the yield of purified sulfur is 50-70%, and sulfur loss with the sorbent reaches 30-50%, which requires a special operation to dissolve sulfur in carbon disulfide or kerosene. The relatively low content of the mouse in the sorbent after cleaning (not more than 0.15-0.30%) makes it difficult to recycle the mouse.
Целью изобретени вл етс очистка газообразной элементарной серы от мышь ка, обеепечиваюн;а минимальные потери серы с сорбентом.The aim of the invention is the purification of gaseous elemental sulfur from arsenic, obejpayuyun, and the minimum loss of sulfur with the sorbent.
Достигаетс это предлагаемым способом очистки газообразной элементарной серы от мышь ка адсорбцией каменноугольными или нефт ными коксами.This is achieved by the proposed method of cleaning gaseous elemental sulfur from the mouse by adsorption by coal or petroleum coke.
Технологи способа состоит в пропускании газообразной элементарной серы через слой сорбента, состо щего из зерен каменноугольного или нефт ного коксов.The process technology consists in passing gaseous elemental sulfur through a layer of sorbent consisting of grains of coal or petroleum coke.
