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.
