Описание:
In methylacrylate production liquid wastes containing considerable amounts of sulfuric acid and organic compounds are formed. Neutralization of sulfuric acid and removal of organic compounds from the effluent water are the essential phases of ammonia sulfate preparation. Methods of purifying waste water formed in methylacrylate production are proposed. Waste water purification is performed by oxidation, floatation and extraction. Combining several physical and chemical methods the most perfect purification is attained. By removing organic impurities from waste water high grade ammonia sulfate may be obtained as by-product.
