    Abstract: A process and system for removing polar components from a process stream in a refinery process without cooling the process stream are disclosed. The process stream is fed to a first adsorber unit to remove contaminants containing sulfur from the process stream. The process stream is processed within the first adsorber unit to remove sulfur containing contaminants. The process stream is processed with the first adsorber unit at substantially the same elevated temperature. The process stream is processed within the first adsorber unit by exposing the process stream to 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. The metal sulfide may be exposed to a stream of oxygen to regenerate the at least one of a metal oxide and a mixed metal oxide. The desulfurized process stream may be exposed to at least one of the regenerated metal oxide and regenerated mixed metal oxide to remove moisture from the desulfurized process stream. The desulfurized process stream is then fed through a second adsorber unit to remove contaminants containing nitrogen from the process stream. The process stream is processed within the second adsorber unit to remove nitrogen containing contaminants, where the process stream being processed at substantially the same elevated temperature. The process stream is processed within the second adsorber unit by exposing the process stream to at least one of a molecular sieve and zeolites to remove nitrogen containing contaminants from the process stream.
