Abstract

Описана установка, в которой различные ступени работают при разных давлениях, для производства азотной кислоты на основе окисления аммиака. Установка содержит реактор, выполненный с возможностью получения потока газа горелки; секцию охлаждения газа, выполненную с возможностью образования охлажденного газа горелки; секцию конденсации, выполненную с возможностью образования водного конденсата азотной кислоты и потока неконденсированных газообразных оксидов азота; секцию абсорбции, выполненную с возможностью производства сырой азотной кислоты и остаточного газа; и систему обработки остаточного газа, выполненную с возможностью образования очищенного остаточного газа. В секции нагрева остаточного газа дополнительный теплообменник выполнен с возможностью приема тепла от потока газа горелки, причем указанный дополнительный теплообменник расположен относительно близко к реактору.A plant is described in which different stages operate at different pressures for the production of nitric acid based on ammonia oxidation. The installation includes a reactor, configured to receive a gas stream of the burner; a gas cooling section configured to form a cooled burner gas; a condensation section configured to form a nitric acid water condensate and a stream of uncondensed gaseous nitrogen oxides; an absorption section adapted to produce crude nitric acid and residual gas; and a residual gas treatment system configured to form purified residual gas. In the residual gas heating section, an additional heat exchanger is configured to receive heat from the burner gas stream, wherein said additional heat exchanger is located relatively close to the reactor.
