Process for separating organic nitrogen compounds from a hydrocarbon stream and alkylation system

摘要

"The Pope to separate organic compounds process of nitrogen from a hydrocarbon stream and a system of alkylation.It is described a process and apparatus for the removal of nitrogen compounds from a substrate of alkylation, such as benzene.A conventional adsorbent bed (46, 114) can be used to adsorb organic nitrogen compounds, basic and a hot bed adsorber (72,162) of acidic molecular sieve can adsorb the weakly basic nitrogen compounds, such as nitriles -. The water facilitates the adsorption of weakly basic nitrogen compounds.It may be advantageous to drive a current of the substrate alkylation (68, 8) of a fractionating column (40,130) of high temperature and suitable concentration of water for the hot adsorbent bed.
