Abstract

Рассматривается способ очистки газового потока, содержащего воспламеняющийся газ, такой как газообразные водород или углеводород. Газовый поток транспортируется в жидкостно-кольцевой насос (18), в который подаются газообразный окислитель и вода. Вода и газовый поток выводятся из насоса (18) потоком разгрузочного газа, который затем отделяется от жидкости, и транспортируются в устройство пиролиза (42) для пиролиза воспламеняющегося газа и окислителя. Любые дисперсные частицы и кислотные частицы в газовом потоке удерживаются водой в насосе с жидкостным кольцом с предотвращением коррозии или закупорки устройства пиролиза (42). Фильтр или другое устройство (40) могут быть предусмотрены для удаления воды из газового потока прежде, чем он поступает в устройство пиролиза (42) .
