Reboiler in propane recovery Producer of polyethylene plastic, Sweden Case story A Swedish producer of polyethylene plastic uses one Alfa Laval DuroShell and two AlfaNova heat exchangers in its system for recovering propane in ethylene cracker off-gases for reuse in the polyethylene production process. The DuroShell acts as a reboiler, performing well thanks to its high vaporization rate, compact size and high pressure durability. The possibility of crossing temperatures in a single unit means a DuroShell can perform heating and vaporization duties using lower grade steam than a traditional shell-and-tube heat exchanger. Results • Highly efficient propane evaporation • Compact size • High vaporization rate • Robust and durable How to contact Alfa Laval Up-to-date Alfa Laval con
