ABSTRACT:
An off-gas from a process for producing styrene from ethylbenzene, which contains non-condensables; in particular, hydrogen, as well as some aromatics; in particular, ethylbenzene, is contacted with a higher boiling absorption oil to scrub aromatics from the off-gas and provide an off-gas essentially free of aromatics. The absorption step is employed as a final treatment of the off-gas; i.e., subsequent to initial treatment of the off-gas by chilling and/or ethylbenzene scrubbing to initially reduce the aromatics content thereof. A preferred absorption oil is the heavy byproducts obtained from a process for producing ethylbenzene, which contains polyethylbenzenes.
