The invention relates to a method and a system (10) for treating synthesis gas from the gasification of carbon-containg solids, wherein a synthesis gas (24) that can be obtained by a gasification of carbon-containing solids is provided. The synthesis gas (27) is cleaned in a gas scrubbing unit (26). The scrubbed synthesis gas (40) is then compressed to an operating pressure for a subsequent synthesis, particularly methanol production (44), from the synthesis gas (40). According to the invention, an intermediate compression of the synthesis gas (27) takes place directly before cleaning in the gas scrubbing unit (26).
L'invention concerne un procédé et une installation (10) pour le traitement de gaz de synthèse issu de la gazéification de matières solides carbonées au moyen desquels est préparé un gaz de synthèse (24) obtenu par gazéification d'une matière carbonée. Ledit gaz de synthèse (27) est épuré au cours d'un lavage de gaz (26). Le gaz de synthèse épuré (40) est ensuite comprimé à une pression de fonctionnement pour une synthèse subséquente, en particulier une production de méthanol (44), à partir du gaz de synthèse (40). Selon l'invention, une étape intermédiaire de compression du gaz de synthèse (27) a lieu juste avant l'épuration effectuée lors du lavage de gaz (26).
