Abstract

L'invention concerne un procédé pour éviter ou minimiser une contamination par une ou plusieurs impuretés gazeuses présentes dans l'atmosphère ambiante, pendant les périodes de temps durant lesquelles un site utilisateur (4) ne consomme pas de gaz, d'une canalisation de gaz véhiculant ce gaz entre une source de gaz (14) et un site utilisateur (4) utilisant ledit gaz. Selon ce procédé, on détermine, pendant ladite période de temps, une valeur de pression (Vpd) correspondant à la pression à l'intérieur d'au moins une portion de ladite canalisation, et on ajuste la pression régnant dans au moins ladite portion de canalisation pour maintenir ladite pression entre une valeur de pression minimale (Vpo) préfixée supérieure à 105 Pa et une valeur de pression maximale (Vpm) préfixée supérieure à la valeur de pression minimale (Vpo), le maintien ou l'ajustage de pression étant réalisé par introduction de gaz sous pression dans au moins ladite portion de canalisation.

The invention relates to a method for avoiding or minimizing contamination by one or more gaseous impurities present in the ambient atmosphere, during periods of time during which a user site (4) does not consume gas, of a gas pipeline. conveying this gas between a gas source (14) and a user site (4) using said gas. According to this method, a pressure value (Vpd) corresponding to the pressure inside at least one portion of said pipe is determined during said period of time, and the pressure prevailing in at least said portion of pressure is adjusted. pipe for maintaining said pressure between a minimum pressure value (Vpo) prefixed greater than 10 5 Pa and a maximum pressure value (Vpm) prefixed greater than the minimum pressure value (Vpo), maintaining or adjusting the pressure being produced by introducing pressurized gas into at least said portion of pipeline.
