Abstract: Monovalent inorganic acids such as hydrofluoric acid can be removed from spent pickling baths by bringing the bath, which shall have a content of sulphuric acid at least equivalent to the metal ion content of the bath, into contact with an organic liquid which contains a compound which forms an adduct with the monovalent inorganic acids. The organic phase extracts the monovalent inorganic acids from the aqueous phase. Metals can then be recovered from the aqueous phase, if desired. The organic phase may then be washed with water, resulting in the monovalent inorganic acids being transferred from the organic phase into the water. The acid aqueous solution thus produced may be used for preparing a fresh pickling bath.
Abstract translation: 通过将含有至少等于浴的金属离子含量的硫酸含量的浴与含有化合物的有机液接触,可以从废酸洗池中除去单价无机酸,例如氢氟酸, 与一价无机酸形成加合物。 有机相从水相中萃取出一价无机酸。 如果需要,可以从水相中回收金属。 然后有机相用水洗涤,导致一价无机酸从有机相转移到水中。 由此生产的酸性水溶液可用于制备新鲜酸洗浴。

Abstract: A powder is produced by atomizing molten material by means of a jet of an atomizing fluid. The atomizing zone is surrounded by a wall defining a comparatively narrow passageway, to the effect that the jet of atomizing fluid will act as a jet pump creating a circulation of the gas in the atomizing chamber. Means are provided for cooling said gas.
