Abstract
EMbaffle Technology is a patented shell and tube heat exchanger technology,
originated by Shell Global Solutions International. The technology was
originally developed for fouling abatement of crude preheaters.
In fouling services, dead zones of the conventional segmental baffle design
reduce the performance of the exchanger with pressure drop increasing during
operation.
In
the EMbaffle design, the tubes are supported by a grid, allowing the fluid to
flow parallel to the tubes, thus avoiding dead zones. This results in
significantly higher performances. EMbaffle technology is applied in many
different crude unit applications. This article presents two cases of
performance monitoring of EMbaffle technology in crude units, the 2-pass
shrouded design and the 3-pass design.
The design, installation, performance monitoring, clean-out and
condition monitoring are discussed.
