Reboiler in propane recovery system

Reboiler in propane recovery mini case story 640x360

A Swedish producer of polyethylene plastic uses one 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.
