A Kenics™ heat exchanger, manufactured by NOV, has helped an Ohio-based speciality chemical manufacturer achieve a new production record
The heat exchanger, which includes Kenics’ highly efficient static mixer technology, is operating at a U-value of approximately 140 (btu/hr. ft2F), compared to the previous U-value level of just 15 (maximum).
Kenics static mixers in each heat exchanger tube significantly reduce the build-up of film commonly associated with empty tubes. Process fluid is continuously pushed from the centre of each tube to the wall and then back to the centre, eliminating thermal gradients and boosting the coefficient inside film.
Easy to install, saving on time and costs, the Kenics heat exchanger is designed to direct fluid flow radially toward the pipe walls and back to the element, regardless of velocity.
Additionally, momentum reversal and flow division also contributes to the high level of mixing efficiency. All processed material is continuously and completely intermixed to eliminate radial gradients in temperature and material composition. As a result, Kenics heat exchangers provide predictable, controlled mixing and extremely efficient thermal transfer.
