Technology Solutions
Ohmstede collaborates with some of the world’s leading refiners and engineers to build heat exchanger components to meet specific process challenges with innovative, proprietary designs. Our goal is to create ongoing improvements and help customers gain greater efficiencies from new and existing equipment.
CB & I / Lummus Helical Baffle Technology
Helixchanger® -- Special shell and tube heat exchanger that can be
constructed with quadrant shaped baffles positioned at an angle to the
tube axis creating a uniform velocity helical flow through the tube
bundle. Benefits include low fouling characteristics and longer run time
between scheduled cleaning.
ConocoPhillips RODbaffle® Technology
RODbaffle® technology uses positive four-point tube support to minimize tube vibration and minimizes pressure drop.
ExxonMobil DTS®
Under an exclusive license agreement with ExxonMobil, Ohmstede
manufactures and installs Dimple Tube Supports (DTS) and Saddle Tube
Supports (STS) to eliminate vibration. DTS and STS components are custom
designed strips for insertion between tubes. DTS and STS strips can be
added either in the shop when constructing a new unit or in the field
when retrofitting tube bundles.
EMbaffle™ Technology
Exclusive U.S. license agreement for this expanded metal baffle
technology, which is similar to a conventional segmental heat exchanger.
It has uniform longitudinal flow on the shell-side (no stagnant zones)
and local cross flow (breaking up boundary layer and improving
performance). It has a three-dimensional shape with uniform open flow
area. Design creates a low pressure drop and less/lower rates of fouling
on the shell-side, provides essentially no risk for tube vibration
failure, provides for energy & CO2 specific savings and allows for increased run time between cleaning.
