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.

Abstract: A process for removing polar components from a process stream in a refinery process without cooling the process stream. The process stream is fed to a first adsorber unit to remove contaminants containing sulfur at substantially the same elevated temperature by exposing the process stream to a metal oxide and/or a mixed metal oxide to remove the sulfur containing contaminants and produce a metal sulfide and a desulfurized process stream. The metal sulfide may be regenerated by exposing it to a stream of oxygen and the desulfurized process stream exposed to the regenerated metal/mixed metal oxide to remove moisture from the stream. The stream is then processed within a second adsorber unit to remove nitrogen containing contaminants at substantially the same elevated temperature by exposing the stream to a molecular sieve and/or zeolite.
