Abstract

L'invention concerne un procédé de traitement continu d'un gaz obtenu à partir d'un procédé industriel, afin de séparer des particules et/ou des substances liquides et/ou gazeuses du gaz et, s'il convient, afin de transférer de la chaleur vers le gaz ou à partir de celui-ci, le gaz étant introduit dans une chambre de traitement (2) et mis au contact d'au moins un liquide de traitement en suspension dans le gaz sous la forme de gouttelettes absorbant lesdites particules et substances et recevant ou émettant de la chaleur depuis le gaz et vers celui-ci, respectivement. Les gouttelettes sont collectées, et du liquide ainsi que du gaz épuré sont extraits à travers différentes sorties (26, 4). Le liquide de traitement est fourni en une quantité suffisante pour obtenir un état d'équilibre entre les deux phases. Selon l'invention, le traitement est exécuté tandis que le gaz est exposé à des infrasons.
