摘要： An off-gas quencher and solid recovery scrubber unit includes a wet flue gas scrubber which has the dual responsibilities of lowering the temperature of the inlet hot gas entering through the scrubber and trapping contaminants from the gas stream into the liquid stream. The hot exhaust gases are first cooled by evaporating the liquid scrubber solution. The contaminants of the exhaust gas are neutralized by a suitable reagent such as sodium hydroxide and the product is collected in the scrubbing solution. Since the solution is continuously recycled, the concentration of the scrubbing agent will be diminished as the scrubbing proceeds, while the concentration of the scrubbing product in the solution will rise to the solubility limit of the product. The scrubbing products start to precipitate and are collected at the bottom of the scrubber and are withdrawn. The scrubbing reagents are continuously replenished to the scrubber. The secondary scrubber is another wet scrubber which uses reagents/water from spray nozzles to scrub off any contaminants that might have escaped the solid recovery scrubber. In addition, the exhaust gas entering the secondary scrubber is cooled below its dew point which results in condensation of water in the scrubber.
摘要翻译：废气猝灭剂和固体回收洗涤器单元包括湿烟道气洗涤器，其具有降低通过洗涤器进入的入口热气体的温度并将污染物从气流捕获到液体流中的双重职责。首先通过蒸发液体洗涤器溶液来冷却热废气。废气中的污染物被合适的试剂如氢氧化钠中和，并将产物收集在洗涤溶液中。由于溶液被连续循环，洗涤剂的浓度随着洗涤进行而减少，而溶液中洗涤产物的浓度将升至产物的溶解度极限。洗涤产物开始沉淀并收集在洗涤器的底部并被抽出。洗涤剂不断补充到洗涤器中。二次洗涤器是另一种湿式洗涤器，其使用来自喷嘴的试剂/水来洗涤可能已经从固体回收洗涤器逸出的任何污染物。此外，进入二次洗涤器的排气被冷却到其露点以下，这导致洗涤器中的水冷凝。

摘要： The potassium salts in aqueous mixtures of potassium fluoride and potassium salts of organic acids are separated and separately recovered by adding a dipolar, aprotic solvent until two liquid phases are present and then separating the phases. The aqueous phase contains the potassium fluoride and the solvent phase contains the potassium salt of an organic acid. Potassium fluoride and potassium 3,5-dichloro-6-fluoro-2-pyridinate, for example, are separately recovered from aqueous mixtures containing both by adding N-methyl-2-pyrrolidinone.

摘要： Hydrogen Fluoride is manufactured from fluorosilicic acid. The fluorosilicic acid is reacted with ammonia to produce aqueous ammonium fluoride and solid silica. The ammonium fluoride is hydrolised in the presence of a mixture of ammonium fluoride and ammonium bifluoride, and the net production of ammonium bifluoride is converted to sodium bifluoride. The sodium bifluoride is decomposed by heating to hydrogen fluoride gas.
