A slipstream of high pressure, cooled isobutane recycle from within an alkylation process unit is used to withdraw hydrofluoric acid from a storage vessel by means of an eductor and discharges the same into a reactor section of the unit. The eductor is preferably constructed of HASTELLOY "C" which provides both corrosion resistance to HF acid and has excellent surface hardness to withstand the highly erosive eductor application. This eductor eliminates potential release of HF acid due to failure of conventional rotating equipment seals or sealing systems, is low cost, has no moving parts, and is fireproof (will not lose containment during a fire).
