A heat exchanger for cutting costs in petrochemical production

In an increasingly competitive market, every petrochemical plant is looking for new ways to keep down costs and increase productivity at the same time. That’s why installing the right heat exchanger can be about more than increasing performance. It’s also an opportunity for increasing savings.

For petrochemical producers, bulky heat exchangers can make for a difficult and expensive installation. Alfa Laval DuroShell offers a simpler – and more cost-effective – installation process. That’s because it has a compact plate-and-shell design that’s smaller and lighter than both shell-and-tube and conventional plate-and-shell heat exchangers.

DuroShell also offers the potential to reduce a plant’s investment in other ways. For example, it can perform condensation and subcooling in the same unit. For certain positions, such as overhead condensing, one DuroShell can therefore do the job of two comparable heat exchangers.

But for DuroShell, the upfront savings are only the beginning. Choosing a shell-and-tube or conventional plate-and-shell heat exchanger may also lead to significantly greater total lifecycle costs. This is due to the added energy consumption as well as money lost to repeated fatigue-related downtime.

DuroShell can help petrochemical plants cut power bills thanks to the ability to provide thermal efficiency 15-20% greater than conventional plate-and-shell heat exchangers. Additionally, the unique construction ensures low long-term maintenance costs thanks to unrivalled fatigue resistance. And DuroShell’s robust design also translates to a longer service life – so it will be many years before the time comes to invest in a new unit.
