超共沸酸精馏法制取浓硝酸

Concentrated nitric acid manufactured by super azeotropic acid distillation process

介绍浓硝酸生产新方法——超共沸酸精馏法制取浓硝酸（简称“新法”），并从理论、实践、设备材料选型等方面论证“新法”的可行性。与硝酸镁法制取浓硝酸相比，“新法”具有投资省、运行费用经济等优点。建议建设中试装置，并尽快建设工业示范装置。

Discribe new production process of concentrated nitric acidconcentrated nitric acid manufactured by using super azeotropic acid distillation process (referred to as “new process”), affirm possibility of the “new process”from view point of theory, practice and type setection of equipment and materials, in comparison with magnesium nitrate process, the “new process” has advantages of less investment and operating cost etc.. It is proposed that pilot plant, and then commercial demostration plants should be built soon.
