Title: Process for the prevention of corrosion in equipment for the distillation of sulfuric-acid-treated hydrocarbons
IPC: C10G17/06
Filed: 1944-11-22
Abstract: The corrosive effect of hydrocarbons of gasoline boiling range which have been contacted with sulphuric acid, especially of isoparaffin-olefin alkylates, during their distillation is prevented by adding a small amount, generally .005-.5 per cent by volume, of an alkali metal salt of a phenol.  This is preferably injected at a point where the alkylate is in turbulent flow and immediately prior to its entry into the still.  Any mono- or poly-hydric phenol such as tricresol, pyrogallol, resorcinol, hydraquinone and, preferably, petroleum phenols or fractions thereof may be used as their sodium salts.  The salts of the petroleum phenols may be used as a solution in a hydrocarbon having a lower boiling point but higher than that of the alkylate whereby separation from the alkylate by distillation is possible. A gas oil or light lubricating oil is preferred.  In an example, sodium salt of petroleum phenols in an equal volume of lubricating oil distillate is added in an amount of .025 per cent, by volume to isobutane-butene prior to distilling.
