A side-stream portion of a Stretford Process solution is taken from the main-stream in order to reduce the amount of deleterious side-products in the solution and the ADA values and vanadium values are salvaged from the side-stream by taking up the ADA values on activated charcoal and the vanadium values in an anion exchange resin. The ADA and vanadium values are recovered for re-cycling back to the Stretford Process.
