US 12,480,059 B2 · Process for treating a feedstock comprising halides

Abstract

A process and a system for conversion of a hydrocarbonaceous feed comprising at least 10 ppmw and less than 10000 ppmw of one or more halides, and at least 20 ppmw and less than 10000 ppmw organically bound nitrogen, to a hydrocarbon product stream by hydrotreatment, in the presence of a material catalytically active in hydrotreatment and an amount of hydrogen, wherein said hydrocarbon product stream comprises an amount of ionic halides and an amount of ammonia, said process including: a) separating in a first separation step at a first separation temperature the mixed product stream to provide an overhead stream and a bottoms stream, b) combining the overhead stream with an amount of wash water and c) separating in a second separation step the combined overhead stream and wash water in a non-polar stream of hydrocarbon product and a polar stream of wash water comprising ammonium halides.

A process for conversion of a hydrocarbonaceous feed comprising at least 10 ppmw and less than 10000 ppmw of one or more halides, and at least 20 ppmw and less than 10000 ppmw organically bound nitrogen, to a hydrocarbon product stream by hydrotreatment, under effective hydrotreatment conditions, in the presence of a material catalytically active in hydrotreatment and an amount of hydrogen, wherein said conversion provides a mixed product stream comprises an amount of ionic halides and an amount of ammonia,

said process comprising the steps of
a) separating in a stripping process at a first separation temperature the mixed product stream to provide an overhead stream and a bottoms stream,
b) combining the overhead stream with an amount of wash water and
c) separating in a second separation step the combined overhead stream and wash water in a non-polar stream of hydrocarbon product and a polar stream of wash water comprising ammonium halides,
wherein the first separation temperature being above the precipitation temperature of the ammonium halides present in the mixed product stream.
