Reboiler in propane recovery system

The DuroShell acts as a reboiler in a Swedish polyethylene plastic plant, performing well thanks to its high vaporization rate, compact size and high-pressure durability.

DATE 2019-10-14

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.
