Abstract

Способ для обработки сточных вод от нефтеперегонного завода, в основном содержащих сероводород и аммиак, а также отходящих кислых газов, в основном содержащих сероводород, при этом указанный способ включает в себя следующие этапы: а) отгонку в отгонной колонне (100) указанных сточных вод (1) при давлении в диапазоне от 8 до 20 бар (от 8 до 20 атм) изб., чтобы получить газовый верхний поток (2), по существу, содержащий сероводород и воду, и жидкий нижний поток (4), по существу, содержащий водный аммиак; b) отгонку во второй отгонной колонне (110) потока (4) при 1-3 бар (при 1-3 атм) изб., чтобы получить газовый верхний поток (5-11) аммиака, существенно чистого на сухой основе, и жидкого нижнего потока (6), содержащего меньше 1 ч./млн сероводорода и меньше 5 ч./млн аммиака, при этом указанной водной композиции предъявляются требования, чтобы она удалялась в сточную канализацию; с) оксидирование при дефиците окислителя до азота и воды аммиака, содержащегося в потоке (11), в аппарате (170) для термического оксидирования, чтобы получить выходной поток (12), содержащий 50-150 ч./млн объемных аммиака и 80-200 ч./млн объемных оксидов азота; d) термическое оксидирование потока (12) в аппарате (160) для термического оксидирования.A method for treating wastewater from an oil refinery, mainly containing hydrogen sulfide and ammonia, as well as acid waste gases, mainly containing hydrogen sulfide, while this method includes the following steps: a) distillation in a stripping column (100) of said wastewater ( 1) at a pressure ranging from 8 to 20 bar (8 to 20 atm) g to obtain a gaseous overhead stream (2) substantially containing hydrogen sulfide and water, and a liquid bottom stream (4) substantially containing aqueous ammonia; b) stripping in a second stripper (110) stream (4) at 1-3 bar (at 1-3 atm) g to obtain a gaseous overhead stream (5-11) of ammonia, substantially pure on a dry basis, and a liquid bottom stream (6) containing less than 1 ppm hydrogen sulfide and less than 5 ppm ammonia, while the specified aqueous composition is required to be disposed of in the sewer; c) oxidizing with an oxidant deficiency to nitrogen and water of the ammonia contained in stream (11) in a thermal oxidation apparatus (170) to obtain an output stream (12) containing 50-150 ppm by volume ammonia and 80-200 ppm by volume nitrogen oxides; d) thermal oxidation of stream (12) in the thermal oxidation apparatus (160).
