Abstract
Official abstract text for this publication.
A process for the production of olefin sulfonates is presented. The process comprising generating olefins from normal alkanes through a dehydrogenation unit to produce a mixture of alkanes and alkenes. The mixture is sulfonated to react the olefins and generate olefin sulfonates. The olefin sulfonates are separated from the normal alkanes to produce a product stream, with the normal alkanes recycled to the dehydrogenation unit.
First claim
Opening claim text (preview).
The invention claimed is: 1. A process for generation olefin sulfonates comprising: passing a hydrocarbon feedstock comprising heavy paraffins in the C14 to C30 range to an adsorption separation unit to generate a feedstream comprising normal alkanes in the C14 to C30 range, and a raffinate stream; passing the feedstream comprising normal alkanes, wherein the alkanes have between 14 and 30 carbon atoms, to a paraffin dehydrogenation unit, thereby generating a first effluent stre…
