Abstract

La présente invention concerne un procédé permettant d'éliminer des contaminants gazeux d'un courant de gaz d'alimentation comprenant du méthane et des contaminants gazeux. Ce procédé comporte plusieurs opérations. On refroidit le courant de gaz d'alimentation de façon à obtenir une boue liquide comprenant le contaminant solide, le contaminant en phase liquide, et une phase gazeuse enrichie en méthane. On introduit la boue liquide ainsi obtenue dans un séparateur cryogénique par le haut duquel on prélève la phase gazeuse enrichie en méthane. On dilue la boue liquide contenant le contaminant en phase liquide, et on la fait passer dans un échangeur thermique dans lequel le contaminant solide se transforme, par fusion, en contaminant en phase liquide. On recycle une partie au moins du contaminant en phase liquide de façon à diluer la boue liquide contenue à l'intérieur du séparateur. Au moyen d'une pompe, ou de préférence un éducteur, on prélève un courant comprenant le contaminant en phase liquide en un point du séparateur inférieur au niveau de boue liquide. On récupère sous forme d'un courant résultant une partie au moins du contaminant en phase liquide prélevé. Une partie au moins en est recyclée vers l'éducteur pour servir de fluide d'entraînement dans le cas d'utilisation de l'éducteur, puis elle est introduite dans le séparateur pour y diluer la boue liquide. L'invention concerne également un dispositif permettant la mise en œuvre du procédé de l'invention, le courant de gaz purifié, et un procédé de liquéfaction d'un courant de gaz d'alimentation.
