Abstract
A process for the removal of residual sulfur compounds from rich liquid caustic is disclosed where a single column containing two reaction zones catalytically oxidizes mercaptans to disulfide oils. The second reaction zone utilizes a bundle of vertical hanging fibers and is maintained as a gas continuous phase comprising from about 20% to about 100% by volume vapor. This process is especially useful as part of a hydrocarbon desulfurization process flow scheme.
