Method of removing entrained sulfuric acid from alkylate

   
   

An improvement in the alkylation of olefins with isoalkanes in the presence of sulfuric acid wherein the sulfuric acid is removed from the product by a mechanical coalescer means prior to fractionation. No water wash or caustic treatment is required. Any sulfonates or sulfonic esters are removed by hydrodesulfurization or decomposition catalyst in a separate reactor or in either the deisobutanizer (DIB) or debutanizer (DB) column.

Una mejora en el alkylation de olefins con los isoalkanes en la presencia del ácido sulfúrico en donde el ácido sulfúrico es quitado del producto por medios mecánicos de un coalescer antes del fraccionamiento. No se requiere ninguna colada del agua o tratamiento cáustico. Cualesquiera sulfonates o éster sulfonic son quitados por el catalizador del hydrodesulfurization o de la descomposición en un reactor separado o en el deisobutanizer (DIB) o la columna del debutanizer (DB).
