С54) СПОСОБ ОЧИСТКИ ОТХОДЯЩИХ ГАЗОВ C54) METHOD FOR CLEANING OF EXHAUST GASES
Изобретение относитс к очистке Промышленных газовых выбросов от токсичных органических веществ способом . каталитического окислени и может быть применено в различных отрасл х промышленности, например в производстве синтетических каучуков, искусственных волокон, в нефтеперерабатывающих и нефтехимических пронзнодствах .The invention relates to the purification of industrial gaseous emissions from toxic organic substances by the method. catalytic oxidation and can be used in various industries, for example in the production of synthetic rubbers, artificial fibers, in oil refining and petrochemical products.
Известно, что в промышленных установках дл каталитической очистки подогрев газовых выбросов до требуемой температуры осуществл етс в выносных или встроенных топках за счет тепла, вьщел ющегос при сгорании природного газа. В топках установок каталитического дожигани в высокотемпературных зонах пламени из азота и кислорода воздуха образуютс окислы азота, KOTojftie выбрасываютс в атмосферу с дымовыми газами , загр зн ее. Концентраци окислов азота в дымовых газах установок каталитического дожигани превьииает ПДК (0,085 мг/ьг) в сотни и тыс чи раз It is known that in industrial plants for catalytic cleaning, gas emissions are heated to the required temperature in remote or built-in furnaces due to the heat absorbed by the combustion of natural gas. In furnaces of catalytic afterburners in high-temperature zones of the flame nitrogen oxides are formed from nitrogen and oxygen of the atmosphere, the KOTojftie is released into the atmosphere with flue gases, which are polluted. The concentration of nitrogen oxides in the flue gases of catalytic afterburners exceeds the MAC (0.085 mg / g) hundreds and thousands of times.
Известен также способ очистки отход щих газов от органических веществ путем каталитического окисОТ ОРГАНИЧЕСКИХ ВЕИЩСТВAlso known is a method of purifying waste gases from organic matter by catalytic oxidation of organic matter.
лени последних на алюмоплатиновом катализаторе АП-56 (0,56 вес.% платины на Afjj.0j,) при предварительном подогреве газов до 500°С, которыйthe last on the alumina-platinum catalyst AP-56 (0.56 wt.% platinum on Afjj.0j,) with preheating of gases up to 500 ° C, which
5 осуществл ют в топке за счет тепла сгорани природного газа 23Однако дымовые газы после ката-, литических реакторов содержат окислы азота.5 is carried out in the furnace due to the heat of combustion of natural gas.
10 Целью изобретени вл етс исключение образовани окислов азота.10 The purpose of the invention is to eliminate the formation of nitrogen oxides.
Поставленна цель достигаетс тем, что очищаеьме газы предварительно смешивают с природным газом, приThe goal is achieved by the fact that the purge gases are pre-mixed with natural gas, with
5 этом концентраци природного газа в очищаемом газе составл ет 13-15 мг/л.5, the concentration of natural gas in the gas to be purified is 13-15 mg / l.
Пример 1. Вентил ционные выбросы от сушильных машин в производстве синтетических дивиийловых каучуков СКД, содержащие окрло 1,5 мг/л толуола, 2-10 мг/м дивинила и его олигомеров, смешивают с природным газом таким образом, чтобы концентраци последнего в получаемой газовоздушной смеси поддерживалайь в пределах 13 мг/л. Затем газовоздушную смесь направл ют в реактор с разогретым до 400 С ката ,лизатором АП-56. В момент начала поступлени на катализатор газовозExample 1. Ventilation emissions from drying machines in the production of synthetic di-flue rubber SKD, containing around 1.5 mg / l toluene, 2-10 mg / m divinyl and its oligomers, are mixed with natural gas so that mixtures maintained within 13 mg / l. Then the gas-air mixture is sent to the reactor with the AP-56 lyezee heated to 400 ° C. At the moment when the gas carrier starts to enter the catalyst
