SYSTEM FOR REMOVING POLAR COMPONENTS FROM A PROCESS STREAM TO PREVENT HEAT LOSS

摘要

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.
