SYSTEM CONTROLLING PROCESS OF HYDROXYLAMINESULFATE WINNING Russian patent published in 2002 - IPC

FIELD: production of synthetic fibers and polyamide resins. SUBSTANCE: invention refers to automatization of technological processes of synthesis of hydroxylaminesulfate from nitrogen oxide with catalytic oxidation of ammonia. System controlling process makes it feasible to raise accuracy of control over ratio of key flows and temperature in contact apparatuses and reactors with allowance for restrictions for technological parameters. It increases conversion of reagents and safety of process which in the long run improves qualitative indices and raises productivity of plant employed in process. EFFECT: improved qualitative indices and raised productivity of plant. 1 dwg, 1 tbl
