Granted: 2002-05-20
Abstract: FIELD: methods of production of nitrogen trifluoride. SUBSTANCE: nitrogen trifluoride is used in chemical industry as stable fluorinating agent and fluorine-containing raw material. In rocketry it is used as oxidant for high-energy components; in electronic industry it is used for cleaning crystals of semiconductors and silicon plates. It is also used in lasers and in chemical vapor phase settling apparatus as cleaning gas. Proposed method of obtaining nitrogen trifluoride consists in bringing in interaction reagents contained in heterogeneous phase gas-solid agent. Used as solid phase is ammonium fluoride NH 4 F•xHF, where "x" ranges from 0.01 to 1.3; interaction with gaseous fluorine is performed at mass ratio of ammonium fluoride of from 0.35 to 500 at 20 to 110 C at forced circulation of reagents. Ammonium fluoride may be used in mixture with inert fluoride of metal of group II or III of Periodic Table, or their mixture. Ammonium fluoride and inert material shall be of the same dispersivity of about 1000-200 mcm. Proposed method is distinguished in high yield of target product at low-cost and easily available raw material. Content of admixtures in product mixture is low as far as safety of process is concerned. EFFECT: reduced power requirements; simple and maintainable equipment. 2 cl, 1 dwg, 1 tbl

Abstract: Изобретение относится к области управления работой газоперекачивающих агрегатов при обеспечении транспортировки газа. Технический результат, полученный при осуществлении средства, воплощающего изобретение, выражается в увеличении диапазона регулирования комплекса компрессорных агрегатов. Для вычисления индивидуальных заданий на частоты вращения используют промежуточную величину, определяемую по разности измеренного прямым или косвенным образом значения регулируемой величины (давления на выходе комплекса компрессорных агрегатов, степени сжатия комплекса компрессорных агрегатов или расхода транспортируемого газа через комплекс компрессорных агрегатов) и заданного значения этой величины с использованием алгоритма, соответствующего одному из известных законов регулирования. Посредством отнесения полученной величины к количеству работающих на нагрузку компрессоров получают среднее требуемое значение частоты вращения ротора каждого компрессора. После этого для определения заданной частоты вращения вала каждого газотурбинного привода по измеренным частотам вращения валов газогенератора газотурбинного привода, вала компрессора, температуре продуктов сгорания перед турбиной газогенератора и/или силовой турбиной газотурбинного привода компрессора, давлению за компрессором газотурбинного привода, давлению газа на входе компрессора и перепаду давлений на конфузоре компрессора определяют величины запасов до ограничений по частотам вращения валов, температуре продуктов сгорания, давлению в камере сгорания, давлению на входе компрессора и расстоянию до границы помпажа компрессора, полученные величины приводят к одному диапазону значений при помощи нормирующих коэффициентов, нормированные величины затем усредняют с учетом направленности ограничений, получая таким образом обобщенные значения запасов до верхних и нижних ограничений по каждому компрессорному агрегату. С использованием обобщенных значений запасов и среднего требуемого значения частоты вращения ротора компрессора определяют требуемое значение частоты вращения ротора для каждого компрессора, которое подают в локальные САУ компрессорных агрегатов в качестве управляющего задания (воздействия). Применение такого способа управления увеличивает диапазон регулирования комплекса компрессорных агрегатов, а вследствие этого улучшает способность системы противостоять возмущающим воздействиям по нагрузке и по изменению внешних условий. 5 ил.
