Claims (12)

1. Способ совместного получения (I) удобрения, выбранного из группы, включающей нитрат аммония, фосфаты аммония и их сочетание, путем непрямой нейтрализации аммиака кислотой, выбранной из группы, включающей азотную кислоту, фосфорную кислоту и их сочетание, и (II) соединения серы, выбранного из группы, включающей элементарную серу, SO2, серную кислоту и сульфатные соли, включающий:
(а) введение содержащего оксид серы газа, образующегося вследствие сгорания серусодержащих углеводородов и содержащего диоксид углерода в концентрации, превышающей концентрацию оксида серы в этом газе, в контакт с аммиаком и водной жидкостью, в результате чего селективно образуется содержащий оксид серы продукт, а конечный газ характеризуется пониженным содержанием SO2,
(б) взаимодействие содержащего оксид серы продукта, образующегося на стадии (а), с реагентом, выбранным из группы, включающей азотную кислоту, фосфорную кислоту, их смесь и соли, образовавшиеся вследствие реакции с участием упомянутых кислот, с получением удобрения и соединения серы и
(в) выделение по меньшей мере части соединения серы из удобрения.1. The method of co-production of (I) a fertilizer selected from the group comprising ammonium nitrate, ammonium phosphates and a combination thereof, by indirectly neutralizing ammonia with an acid selected from the group comprising nitric acid, phosphoric acid and a combination thereof, and (II) sulfur compounds selected from the group comprising elemental sulfur, SO 2 , sulfuric acid and sulfate salts, including:
(a) the introduction of a gas containing sulfur oxide, resulting from the combustion of sulfur-containing hydrocarbons and containing carbon dioxide in a concentration exceeding the concentration of sulfur oxide in this gas, into contact with ammonia and an aqueous liquid, as a result of which a product containing sulfur oxide is selectively formed, and the final gas characterized by a reduced content of SO 2 ,
(b) reacting the sulfur oxide-containing product formed in step (a) with a reagent selected from the group consisting of nitric acid, phosphoric acid, a mixture thereof and salts formed as a result of a reaction involving said acids to produce a fertilizer and sulfur compound, and
(c) recovering at least a portion of the sulfur compound from the fertilizer. 2.

Способ по п. 1, в котором реагент на стадии (б) является кислым и по завершении стадии (б) проводят обработку восстановителем с получением восстановленного соединения серы. 8. The method according to p. 1, in which the reagent in step (b) is acidic and, upon completion of step (b), a reducing agent is processed to obtain a reduced sulfur compound. 9. Способ по п. 1, в котором содержащий серу газ образуется в результате процесса десульфуризации топочного газа. 9. The method of claim 1, wherein the sulfur-containing gas is formed as a result of the flue gas desulfurization process. 10. Способ по п. 9, в котором содержащий серу газ образуется в результате процесса десульфуризации топочного газа мокрой очисткой газов известью. 10. The method according to p. 9, in which the sulfur-containing gas is formed as a result of the process of desulfurization of the flue gas by wet cleaning of gases with lime. 11. Способ по п. 9 или 10, в котором степень удаления SO2 мокрой очисткой газов известью составляет менее 90%.11. The method according to p. 9 or 10, in which the degree of removal of SO 2 by wet cleaning of gases with lime is less than 90%. 12. Удобрение, полученное по любому из пп. 1-11. 12.
