摘要： A process for removing sulfone from a liquid hydrocarbon containing a concentration of sulfone by mixing a liquid acid therewith and thereafter separating the resulting admixture into an acid phase and a hydrocarbon phase. The hydrocarbon phase has a concentration of sulfone less than such concentration in the liquid hydrocarbon.

摘要： Disclosed is a process for separating sulfone and hydrogen fluoride from hydrocarbon streams containing a concentration of such compounds. An extraction solvent laden with sulfone and HF is contacted with a reversible base in order to remove the HF therefrom. The thus-treated extract stream is separated into a water stream that can be reused as the water extractant and a sulfone stream that is suitably free of HF.

摘要： Disclosed is an alkylation process which utilizes a mixture of sulfone and hydrogen fluoride as an alkylation catalyst. The process provides for the regeneration of an alkylation catalyst having ASO therein by separating HF from the ASO and sulfone components. The ASO and sulfone are thereafter separated to provide sulfone which is substantially free of ASO.

摘要： Methods and apparatus relate to separating and removing aromatic compounds from a hydrocarbon stream. Splitting of the hydrocarbon stream into constituents as desired relies on a membrane and distillation columns that supply feed into the membrane and receive retentate and permeate streams output from the membrane. Configurations employing the membrane and the distillation columns enable benzene recovery and facilitate efficient separation.
