ABSTRACT:
A new thermal swing adsorption process for the separation of a bulk liquid mixture into its respective components wherein a novel rinse step is employed to achieve high product recovery with a low energy of separation. The invention is particularly useful for separating liquid mixtures containing azeotropes or close-boiling components which are difficult to separate using conventional techniques such as distillation or routine termal swing adsorption. A given example is the separation and recovery of methyl acetate from a bulk liquid mixture containing methyl acetate and water.
