Abstract
The present invention involves processes and equipment for handling chloride in an ionic liquid alkylation system. The processes involve not only breaking down the organic chloride to active HCl for ionic liquid activation, but also recovering HCl in the effluent downstream to maintain the HCl requirements while also reducing HCl emissions. This equipment may be used in conjunction with an isomerization reaction zone which is integrated into the ionic liquid alkylation process to further isomerize n-paraffins to isoparaffins for recycle to the alkylation reaction zone.
