Abstract
An organic feed stream contg. olefinic hydrocarbon(s) is sepd. into an overheads stream of ethylene (prefd.), propylene, butenes and/or butadiene and a bottoms liq. contg. other olefinic hydrocarbon liqs. including 2-7C hydrocarbons. The improvement comprises adding below 700 ppb of a stable free radical (I) to the feed stream to inhibit fouling by the bottoms liq., (I) being a nitroxide having a b.pt. above the sepd. olefinic cpd(s). such that (I) remains in the bottoms. (I) may be produced in situ from a precursor.
