ABSTRACT:
An apparatus and process for separating acid soluble oil (ASO) from HF to purify same for reuse. The apparatus includes an alkylation HF rerun tower having an upper chamber and a lower chamber with liquid-vapor contact means in the upper chamber and an eductor and liquid-vapor contact means in the lower chamber. A stream of HF catalyst containing ASO is introduced into the upper chamber and is intimately contacted with an isoparaffin for separation of the HF and ASO. The ASO is collected in the lower chamber and is circulated through same and the eductor during which same is contacted by a vaporous isoparaffin for further separation of HF and ASO.
