Title (EN) DEVICE AND PROCESS FOR DRY-CLEANING PROCESS USING CARBON DIOXIDE AND A DIVIDED PRESSURE VESSEL
(FR) RECEPTACLE SOUS PRESSION DIVISE POUR SYSTEMES A BASE DE DIOXYDE DE CARBONE ET PROCEDES D'UTILISATION
Abstract: front page image
(EN)Processing systems employing one or more divided pressure vessels (653) are described. These systems may allow for multiple solvent baths each having a different chemical composition to be stored and/or processed in a single pressure vessel (653) while maintaining the different chemical compositions of the multiple solvent baths. Thus, such systems employing one or more divided pressure vessels (653) may provide the improved operational efficiency of a carbon dioxide based system having multiple solvent baths while decreasing the capital costs that may be associated with such systems.
(FR)L'invention porte sur des systèmes de traitement utilisant un ou plusieurs récipients à pression divisés. Ces systèmes permettent de stocker et/ou de traiter plusieurs bains de solvant ayant chacun une composition chimique différente dans un seul récipient à pression tout en conservant les différentes compositions chimiques de ces bains de solvant. Ces systèmes à un ou plusieurs récipients permettent d'obtenir un meilleur rendement dans un système à base de dioxyde de carbone à plusieurs bains de solvant et de réduire les frais d'investissement pouvant être associés à de tels systèmes.
