Abstract

L'invention a trait à l'élimination totale de dépôts aqueux dans des conduites destinées au transport de fluide gazeux. Selon le procédé, on envoie par tuyère à l'extrémité d'au moins un éjecteur à air comprimé, en communication avec le pipe-line, un fluide moteur pressurisé (par exemple sous 4 à 8 bars) qui aspire et entraîne le fluide gazeux (air + vapeur d'eau), le mélange de fluide étant ensuite refoulé à l'autre extrémité de l'éjecteur. En pratique, on utilise des éjecteurs multiétagés, par exemple en série. Selon une autre application du procédé, on effectue la mise en gaz du pipe-line pendant que l'on maintient le vide dans l'éjecteur de façon à se trouver à tout moment en dehors des limites d'inflammabilité du fluide gazeux. Application notamment au séchage et à la mise ultérieure en pression de pipe-lines de gaz naturel.
