Design, Construction and Start up of a Helical Baffle Heat Exchanger in Tabriz Petrochemical Company

Nowadays helical baffle heat exchangers are considered as a modern technology which are designed and used to fulfill shortcomings from the common exchanger equipped with segmental baffles. This type of baffles have many advantages, however, a few technical and scientific information have been published for their design in literatures. Implementation of the outcomes of this research at Tabriz petrochemical company reveals that significant improvements can be achieved. The results indicate better performance can be achieved by the helical designed baffles rather than segmental baffles. Also presented correlation based on rapid design algorithm has been modified and reformed. This paper presents thermal analysis of helical baffles in compare with segmental baffles using CFD analysis. The optimum range of baffleʹs overlaps has been identified within the range 0.4 to 0.6. The outcomes of this project show 50% lower operating costs in compare with a segmental baffle and 3 times higher running operating time without fouling problem.
