Description
оптимальным расходом природного газа дл поддержани нормальной восстановительной среды в зоне реакции с учетом изменени процесса абсорбции и изменени содержани окислов азота и кислорода в хвостовых газах. Было подтверждено, что определенное положение нижней границы температурного пол зоны реакции реактора каталитической очистки вл етс показателем оптимального разложени окислов азота, содержащихс в хвостовых газах на входе в реактор.optimal consumption of natural gas to maintain a normal reducing environment in the reaction zone, taking into account changes in the absorption process and changes in the content of nitrogen oxides and oxygen in the tail gases. It was confirmed that a certain position of the lower limit of the temperature field of the catalytic cleaning reactor reaction zone is an indicator of the optimal decomposition of nitrogen oxides contained in the tail gas at the entrance to the reactor.
Верхн граница температурного пол стабилизируетс регул тором температуры после реактора.The upper limit of the temperature field is stabilized by a post-reactor temperature controller.

азота в реакторе каталитической очистки производства слабой азотной кислоты под давлением путем воздействи па подачу природного газа в реактор и добавочного воздуха на установку абсорбции, отличающийс тем, что, с целью оптимального управлени процессом и сокращени расхода газа, подачу газа в реактор осуществл ют по соотношению расходов газа и добавочного воздуха на установку абсорбции с коррекцией по разности температур хвостовых газов и минимальной температуры температурного пол зоны реакции реактора.Nitrogen in a catalytic purification reactor for the production of weak nitric acid under pressure by affecting the supply of natural gas to the reactor and the additional air to an absorption unit, characterized in that, in order to optimally control the process and reduce the gas flow, the gas is supplied to the reactor gas and additional air to the installation of absorption with the correction of the temperature difference of the tail gases and the minimum temperature of the temperature field of the reaction zone of the reactor.
2. Способ ио п. 1, отличающийс тем, что задание регул тору коррекции по перепаду температур устанавливают в пределах 10-20С, преимущественно 15+ГС.2. The method of clause 1, characterized in that the setting of the temperature differential correction controller is set in the range of 10-20 ° C, preferably 15 + HS.
