A sorption system is disclosed that includes a sorbent material and a fluid, in which the sorbent material and fluid in combination have a pressure index of at least 1.2.

Targeted application of anti-fouling mechanisms in a heat exchange system produces higher rates of energy recovery. The anti-fouling mechanisms with high mitigation rates can be deployed at only the hottest portions of a pre-heat train that experience the highest rates of fouling and heat loss. In application, bundles of corrosion resistant smoothed tubes are deployed in the late pre-heat train to significantly reduce the formation of harder deposits. Vibration can be used as an adjunct approach in conjunction with the corrosion resistant, smooth tubes, or deployed alone on existing bundles. The use of high performing, more durable exchangers in select locations justifies the increased cost of these components.

Crude oil pre-heat train with improved heat transfer

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.
