    Abstract: A method of utilizing a divided pressure vessel in a processing system employing a carbon dioxide based solvent includes transferring a first carbon dioxide based treating solution from a first liquid chamber in a divided pressure vessel having a plurality of liquid chambers to a processing vessel, returning the first treating solution from the processing vessel to the divided pressure vessel, transferring a second carbon dioxide based treating solution having a composition different from the first treating solution from a second liquid chamber in the divided pressure vessel to a processing vessel, and returning the second treating solution from the processing vessel to the divided pressure vessel. A divided pressure vessel may allow multiple solvent baths each having a different chemical composition to be stored and/or processed in a single pressure vessel while maintaining the different chemical compositions of the multiple solvent baths. Thus, such divided pressure vessels 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.

    Abstract translation: 在使用二氧化碳基溶剂的处理系统中利用分压压力容器的方法包括将具有多个液室的分压压力容器中的第一二氧化碳基处理溶液从第一液室转移到处理容器, 将处理容器的第一处理液分离成压力容器,将具有与第一处理液不同的组成的第二二氧化碳类处理液从分压器中的第二液体室转移至处理容器,并将第二处理 从处理容器到分压压力容器的溶液。 分压压力容器可以允许每个具有不同化学组成的多个溶剂浴在单个压力容器中储存和/或加工,同时保持多个溶剂浴的不同化学组成。 因此,这种分开的压力容器可以提供具有多个溶剂浴的具有二氧化碳的系统的改进的操作效率,同时降低可能与这种系统相关联的资本成本。
