ТЕХНОЛОГИИ ПОЛУЧЕНИЯ ЖИДКИХ УГЛЕАММОНИЙНЫХ И АЗОТНО-КАЛЬЦИЕВЫХ УДОБРЕНИЙ НА ОСНОВЕ ВТОРИЧНОГО СЫРЬЯ АЗОТНОТУКОВЫХ ПРОИЗВОДСТВ

Аннотация

Subjects of research: expanders gas, calciumcontcnts slimes, nitrate ammonia, urea, carboammonium salts, liquid fertilizers, bottom rest of monocthanolamine, solution of copperammonium cleaning, phosphate of carboammonium. Purpose of work: physicochemical justification and development of technology liquid carboammonium and nitrogcn-calsium fertilizers on base of the secondary ores of nitrogenfertilizer manufactures with establishment optimal technological parameters and research ways stabilization of carboammonium salts. Methods of research: chemical, physicochemical, visual-polythcrmal, X-ray. The results obtained and their novelty: established raw effect technological parameters to process obtaining liquid carboammonium and nitrogcn-calcium fertilizers, their contents and properties, detecting optimal technological parameters. Development their technology with using secondary ores of nitrogenfertilizer manufactures. Established conditions stabilization carboammonium salts. Practical value: results of executable research become scientific base of for creating technology of liquid carboammonium and nitrogen-calcium fertilizers on base of the secondary ores - expanders gas, calciumcontents slimes, and also fertilizers with additives urea and ammonium saltpeter, bottom rest of monoethanolamine, solution of copperammonium cleaning, phosphate of carboammonium. Development ways stabilization carboammonium salts and select dispersants. . Degree of embed and economic effectively: proposed technology has been tested on «farg’onaazot» model set, experimental batches of liquid carboammonium and nitrogcn-calcium fertilizers were produced. Development technical conditions, initial data to projection, technological regulation, recommendation to use. The economic effect of production of 1 ton of 100% N in dependence from grade of fertilizer, comparison with ammonium saltpeter, for 61.13-187.98 thousand sum, and rise crops of cotton-raw to 4-15% Field of application: chemical industry, agriculture.
