Abstract
A system and/or process for decreasing the level of at least one organic fluoride present in a hydrocarbon phase contained in an alkylation settler by contacting the hydrocarbon phase with an HF containing stream, containing greater than about 80 wt. % and less than about 94 wt. % HF, in the intermediate portion of the settler which contains at least one tray system, with each tray system comprising a perforated tray defining a plurality of perforations and a layer of packing below the perforated tray, are disclosed.
Claims5
A system comprising:
- a) an alkylation reactor;
- b) a settler, having an upper portion, an intermediate portion, and a lower portion wherein said intermediate portion contains at least one tray system comprising a perforated tray defining a plurality of perforations and a layer of packing below said perforated tray;
- c) a feed conduit operably related in fluid flow communication to said alkylation reactor;
- d) a settler feed conduit operably related in fluid flow communication to said alkylation reactor and to said intermediate portion of said settler at a location below said lower-most tray system;
- e) an HF feed conduit operably related in fluid flow communication to said intermediate portion of said settler at a location above said upper-most tray system;
- f) an alkylate containing product conduit operably related in fluid flow communication to said upper portion of said settler;
- and
- g) an alkylation catalyst conduit operably related in fluid flow communication to said lower portion of said settler and to said alkylation reactor.
