    摘要: A process for the regeneration of spent sulfuric acid including contacting spent sulfuric acid containing acid soluble oils (ASO) with sulfur dioxide to extract at least a portion of the ASO from the spent sulfuric acid into the sulfur dioxide. The sulfuric acid phase having a reduced ASO content and a sulfur dioxide phase containing at least a portion of the ASO may be recovered. The resulting sulfuric acid and sulfur dioxide phases may be further separated to recover ASO, sulfur dioxide, and sulfuric acid.

    摘要: A process for the alkylation of isobutane is disclosed wherein isobutane is fed to two separate alkylation systems. The effluent from the first alkylation system is fed to an interim debutanizer where the C4's are separated from the alkylate product. The overhead C4 product is then fed to the second alkylation system to provide the isobutane. The effluent from the second alkylation system is fed to a traditional deisobutanizer to prevent any build up of normal butanes in the system.
