    摘要： Refining processes for recovering HF from acid soluble oils (ASO) generated by the HF recovery unit of an HF alkylation unit are provided. ASO containing HF is removed from the HF recovery unit and contacted with water to form a system having two phases, an aqueous HF containing phase and an organic phase. After phase separation, the aqueous HF containing phase passes through a bed of fluidized NaF crystals, where the NaF reacts with the HF to form salts having the general formula NaF·nHF. Flow of the aqueous HF containing phase to the bed continues until exhaustion of the bed, as determined by the detection of HF in the effluent. After exhaustion of the bed, the process provides for the regeneration of the bed and release of anhydrous HF which is then returned to the HF alkylation unit.
