Abstract

Процесс и устройство для регенерации кислоты и металла из отработанных кислых растворов включает в себя этапы необязательного концентрирования (110) раствора до концентрата раствора или твердого вещества, пирогидролиза (114) для регенерации кислоты и образования гранул оксида металла, и восстановления оксида до металла в реакторе двухстадийного восстановления (116, 118) с использованием не полностью сгоревшего топлива в качестве восстанавливающего агента. Также раскрыт процесс двухстадийного восстановления и реактор для получения железа прямого восстановления (ЖПВ) из железооксидных руд или отходов, включающий в себя первую стадию (416), на которой оксидное сырье приводят в контакт с топливом и субстехиометрическим количеством источника кислорода для получения оксида с более низкой степенью окисления, и вторую стадию (418), на которой оксид с более низкой степенью окисления приводят в контакт с отходящими газами с первой стадии для получения металлического железа.The process and device for the regeneration of acid and metal from spent acidic solutions includes the steps of optional concentration (110) of the solution to a solution or solid concentrate, pyrohydrolysis (114) to regenerate the acid and form metal oxide granules, and reduction of the oxide to metal in a two-stage reactor. recovery (116, 118) using incompletely burnt fuel as a reducing agent. Also disclosed is a two-stage reduction process and a reactor for producing direct reduced iron (DRI) from iron oxide ores or waste, including the first stage (416), in which the oxide feedstock is contacted with fuel and a substoichiometric amount of an oxygen source to obtain an oxide with a lower the oxidation state, and a second stage (418) in which the lower oxidation state oxide is contacted with the off-gases from the first stage to produce metallic iron.
