Description
Несмотр на то, что кислый гудрон, получаемый при очистке нефтепродуктов , содержит значительно1е количества дефицитной серной кислоты , до сих I1OD НС разрешен вопрос об утилизации кислого гудрона. Между тем отходы кислого гудрона достигают на бакинских нефтеперерабатывающих заводах таких количеств, что спуск его в море может вредно отразитьс на рыбном хоз йстве страны. Предлагаетс использовать кислые гудроны как местное сырье дл получени минеральных удобрений (суперфосфата и фосфатно-органического удобрени ).Despite the fact that the acidic tar obtained during the purification of petroleum products contains a significant amount of deficient sulfuric acid, the issue of the disposal of acidic tar has been resolved until now. At the same time, sour tar waste reaches such quantities at Baku refineries that its descent into the sea can be harmful to the fisheries of the country. It is proposed to use acidic tars as a local raw material for the production of mineral fertilizers (superphosphate and phosphate-organic fertilizer).
Описываемый способ получени суперфосфата отличаетс тем, что фосфатное сырье (апатиты и фосфориты) обрабатываетс кислым гудроном.The described method for producing superphosphate is characterized in that the phosphate raw materials (apatites and phosphates) are treated with acidic tar.
Так как кислый гудрои при обыкновенной температуре находитс в |1Сч утвердом состо нии, смешение его с фосфоритом и апатитом реко .мендуетс производить при нагревании; в результате получаетс порошкообразный продукт.Since the acidic Gudroi at an ordinary temperature is in the | 1Ch state, its mixing with phosphate and apatite is recommended to be performed when heated; the result is a powdered product.
Продукт, получепный после смешивани фосфорита и апатита с кислым гудроном, кроме суперфосфата, содерм ит 30% органических соединений, которые улучшают физические и физико-химические свойства почвы.The product obtained after mixing phosphate and apatite with acidic tar, except superphosphate, contains 30% organic compounds that improve the physical and physicochemical properties of the soil.
Кроме лого, кислый гудрои содержит около 1,5% азота, вл ющегос одним из важнейших элементов питани растений.In addition to the logo, acidic food contains about 1.5% nitrogen, which is one of the most important plant nutrients.
При возможности более целесообразного использовани органической части гудрона фосфатно-органическое удобрение можно разделить иа органическую часть и на суперфосфат. Дл отделени органическойIf possible, more appropriate use of the organic part of tar phosphate-organic fertilizer can be divided and the organic part and superphosphate. To separate organic

части от минеральной можно использовать растворители, иолучаемые из. нефти.parts from mineral can be used solvents, and obtained from. of oil.
При проведении опытов дл отделени органической части от фосфатно-органического удобрени в качестве растворител примен ли бензол. Экстрагирование производили в аппарате Сакслета. Отделение органической части от минеральной происходило в течение 4-5 часов. Органическа часть фосфатно-органического удобрени (соотношение кислого гудрона к фосфориту l:ij составл ла-30%. Минеральна часть (т. е. суперфосфат) содержала около 8% усво емого Р2О5.In experiments to separate the organic part from the phosphate-organic fertilizer, benzene was used as a solvent. Extraction was performed in the apparatus Saxlet. The separation of the organic part from the mineral occurred within 4-5 hours. The organic part of the phosphate-organic fertilizer (the ratio of acidic tar to phosphate l: ij was la-30%. The mineral part (i.e. superphosphate) contained about 8% of the digestible P2O5.
Дл повышени содержани усво емого Р2О5 в суперфосфате (т. е. в минеральной части) выделенный суперфосфат рекомендуетс обрабатывать .новыми порци ми кислого гудрона.In order to increase the content of absorbable P2O5 in superphosphate (i.e., in the mineral part), the isolated superphosphate is recommended to be treated with new portions of acid tar.
В зависимости от содержани rl2S04 в кислом гудроне и после вторичной обработки можно получить суперфосфат с содержанием усво емого Р20.5 в количестве, равном содержанию его в обычном суперфосфате . Кроме того, качество его повышаетс , так как суперфосфат, полученный от смешени кислого гудрона с фосфоритом, благодар незначите.льному содержанию органических соединений, не слеживаетс в твердые или в зкие комки.Depending on the content of rl2S04 in acid tar and after secondary processing, it is possible to obtain superphosphate with an assimilable P20.5 content in an amount equal to its content in ordinary superphosphate. In addition, its quality is enhanced, as the superphosphate obtained from mixing acidic tar with phosphate, due to its low content of organic compounds, does not clump into hard or viscous lumps.
Произведенные лабораторные исследовани показали, что получеиное фосфатно-органпческое удобрение ие вли ет отрицательно на растени , не угнетает микробиологические ироцессы в почве и что органическа часть в иочве разлагаетс .Laboratory studies have shown that the resulting phosphate-organic fertilizer does not adversely affect the plants, does not inhibit the microbiological processes in the soil, and that the organic part of the soil decomposes.
