翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Hydrochloric acid regeneration ： ウィキペディア英語版 Hydrochloric acid regeneration Hydrochloric acid regeneration or HCl regeneration refers to a chemical process for the reclamation of bound and unbound HCl from metal chloride solutions such as hydrochloric acid. ==Field of application== The commercially most relevant field of application for HCl regeneration processes is the recovery of HCl from waste pickle liquors from carbon steel pickling lines. Other applications include the production of metal oxides such as, but not limited, to Al2O3 and MgO as well as rare earth oxides by pyrohydrolysis of aqueous metal chloride or rare earth chloride solutions. A number of different process routes are available. The most widely used is based on pyrohydrolysis and adiabatic absorption of hydrogen chloride in water, a process invented in the 1960s. However tightening environmental standards and stringent air permit policies render it increasingly difficult to establish new pyrohydrolysis based acid regeneration plants. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Hydrochloric acid regeneration」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
