Abstract
A process for separating or stripping lighter components from a heavier hydrocarbon feedstock contaminated with or otherwise including light components. The separation is accomplished by introducing the feedstock into a column and allowing the feedstock to flow through the column, contacting a first stripping medium and a second stripping medium. The first stripping medium entrains the lighter components. The second stripping medium entrains the first stripping medium and any lighter components remaining in the feedstock. Preferred first stripping media include hydrogen, methane, propane, and other inert gas and preferred second stripping media include nitrogen and other inert gas.
