System for removing polar components from a process stream to prevent heat loss

Abstract

A system for removing polar components from a process stream in a refinery process without cooling the stream is disclosed. The stream is fed to a first adsorber unit to remove contaminants containing sulfur from the stream at substantially the same elevated temperature. The stream is processed within the first adsorber unit by exposing the stream to at least one of a metal oxide and a mixed metal oxide to remove the sulfur containing contaminants and produce a metal sulfide and a desulfurized stream. The desulfurized stream is then fed through a second adsorber unit to remove contaminants containing nitrogen from the stream at substantially the same elevated temperature. The stream is processed within the second adsorber unit by exposing the stream to at least one of a molecular sieve and zeolites to remove nitrogen containing contaminants from the stream.

1 . A system for removing polar components from a high temperature process stream having an elevated process temperature in a refinery, comprising:
 a first adsorber unit to remove contaminants containing sulfur from the high temperature process stream, wherein the first adsorber unit removes the sulfur containing contaminants at temperature substantially the same as the elevated process temperature; and   a second adsorber unit to remove contaminants containing nitrogen from the high temperature process stream, wherein the second adsorber unit removes the nitrogen containing contaminants at temperature substantially the same as the elevated process temperature.   
     
     
         2 . The system according to  claim 1 , wherein the first adsorber unit containing at least one of a metal oxide and a mixed metal oxide, wherein the process stream being exposed to the at least one of a metal oxide and a mixed metal oxide to remove the sulfur containing contaminants from the process stream and produce a metal sulfide and a desulfurized process stream. 
     
     
         3 . The system according to  claim 1 , wherein the second adsorber unit containing at least one of a molecular sieve and zeolites to remove nitrogen containing contaminants from the process stream. 
     
     
         4 . The system according to  claim 3 , wherein the second adsorber unit containing at least one of a molecular sieve and zeolites to remove nitrogen containing contaminants from the process stream.
