Distillation is a separation technique that involves heating a feed liquid to change its phase from liquid to vapor within a distillation column, where the differences in volatility allow for the cooling and liquefaction of product fractions to be extracted. This process requires a significant amount of energy for both the latent heat of evaporation and the latent heat of condensation. This document introduces the principles of hiTRAN (CalGavin Ltd: UK), a heat transfer enhancement medium that has been widely used for over 30 years in the processes of the petrochemical and related industries, and its application examples in the field of distillation, specifically aimed at improving the heat transfer efficiency on the tube side of multi-tube (shell & tube) heat exchangers. [Contents] ■ Introduction ■ Distillation Process and Types of Heat Exchangers ■ hiTRAN Heat Transfer Enhancement Technology ■ Design Proposals for hiTRAN Modifications of Existing Process Heat Exchangers and Expected Benefits ■ Conclusion *For more details, please refer to the PDF document or feel free to contact us.

Free membership registration"hiTRAN" destroys the stagnant boundary layer of the fluid inside the heat exchanger tubes and promotes mixing (turbulent vortex formation), thereby enhancing heat transfer. It can be installed not only in new systems but also simply inserted into existing heat exchangers, resulting in several times improvement in heat transfer. The "hiTRAN" heat transfer enhancement technology brings significant benefits to companies in petroleum refining, chemical process industries, steelmaking, and other sectors that require heat recovery. 【Features】 ■ Improvement in product quality ■ Enhanced plant operability ■ Lightweight and compact design ■ Lower costs for new manufacturing, etc. 【Regarding the loan of test equipment】 - For verification experiments of Oil Coolers hiTRAN for ID13mm heat transfer tubes. Please consult us regarding length and quantity! - For performance evaluation verification Ultra-compact heat exchangers (aluminum heat transfer tubes and PVC body) *For more details, please download the PDF or contact us.
