Refinery catalytic cracker feed preheat service

Use of smooth high alloy tubes in otherwise corrosive service has been common practice since the 1950s. Tube metallurgy is selected to minimize corrosion while in service. The tubes therefore maintain their smooth, shiny finish. Without sites for fouling deposits to attach or accumulate, the clean heat-transfer coefficient is maintained. This idea has been used with success in refinery catalytic cracker feed preheat service, placing slurry oil on the tube side and vacuum gas oil on the shell side.
