Description
Изобретение относитс к процессам технической очистки технологических газов и может найти свое применение в химической, электрохимическбй и других отрасл х промыпленности. Известен способ факельного дожигани горючих компонентов газовых выбросов. В этом случае дурнопахнущие и токсичные органические примеси окисл ют при высокой температуре (около 1000°с) путем их ввода в факел , образованный от сжигани газообразного топлива fl. Недостаток этого способа - большо грасход топлива, необходимого дл под держани температурного уровн реак ции высокотемпературного окислени . Наиболее близким к предлагаемому по технической сущности и достигае .мому результату вл етс способ . очистки газовых выбросов, содержащих смесь высоко- и низкокип щих углево дородов (З г/м) путем их охлаждени и каталитического окислени . Причем часть продуктов используетс в качестве окислител на стадии окислени 2 . Недостатком известного способа вл етс низка эффективность процес са при высокой (3 г/м) концентрации вредных примесей. Цель изобретени - обеспечение возможности эффективной очистки газо вых выбросов в случае их высокой концентрации. Поставленна цель достигаетс тем, что согласно способу очистки газовых выбросов, содержащих смесь высокой и низкокип цих углеводородов путем их каталитического окислени , исходный газовый поток охлаждают, образовавшийс при этом конденсат сжигают в факеле, а несконденсированные выбросы раздел ют на два потока, один из которых используют в качестве окислител при факельном сжигании, а второй смешивают с продуктами факельного джигани и подают на каталитическое окисление. При этом соотношение потоков несконденсированных выбросов, направл емых на факельное сжигание и каталитическое окисление устанавливают равным 0,6-1,0:1,0. . Кроме того, количество продуктов факельного сжигани , подаваемых на смешение с несконденсированными вы{}росс1ми , подаваемыми на каталитическое окисление, поддерживают равнымThe invention relates to the process of technical cleaning process gases and can find its application in the chemical, electrochemical and other industrial sectors. The known method of torch afterburning of combustible components of gas emissions. In this case, malodorous and toxic organic impurities are oxidized at a high temperature (about 1000 ° C) by introducing them into a flare formed from the combustion of gaseous fuel fl. The disadvantage of this method is the large consumption of fuel necessary to maintain the temperature level of the high-temperature oxidation reaction. The closest to the proposed technical essence and achieved my result is the method. purification of gas emissions containing a mixture of high- and low-boiling hydrocarbons (3 g / m) by cooling and catalytic oxidation. Moreover, a part of the products is used as an oxidizing agent at the oxidation stage 2. The disadvantage of this method is the low efficiency of the process at a high (3 g / m) concentration of harmful impurities. The purpose of the invention is to provide the possibility of effective purification of gas emissions in case of their high concentration. The goal is achieved by the method of purification of gas emissions containing a mixture of high and low-boiling hydrocarbons by catalytic oxidation, the initial gas stream is cooled, the condensate formed is burned in the flare, and uncondensed emissions are divided into two streams, one of which is used as an oxidizer during flare combustion, and the second is mixed with flare jig products and fed to catalytic oxidation. At the same time, the ratio of uncondensed emissions to the flaring and catalytic oxidation flows is set to 0.6-1.0: 1.0. . In addition, the number of flare products supplied for mixing with uncondensed you {} Russia supplied for catalytic oxidation is maintained equal to
