Petrochemicals

The chemical sector accounts for as much as 10% of global energy consumption. With energy costs representing a substantial portion of the average petrochemical plant’s operating budget, more efficient use of energy has become critical for maintaining profitability in this competitive industry. And because direct CO2 emissions from primary chemical production amount to 7% of the world’s total CO2 emissions, energy efficiency in petrochemical processing is critical for accelerating global sustainability as well.

Alfa Laval has decades of experience working with petrochemical plants to optimize the efficiency of their processes. We offer a broad portfolio of efficient heat exchangers that make it possible to recover more waste heat, and thereby reduce fuel needs and your carbon footprint, while simultaneously boosting production capacity and minimizing material consumption. With more efficient thermal solutions, you can even save money by, for example, using lower grade steam, or generate additional income by selling off surplus electricity and heat to neighbouring plants.

See the numbers: energy efficiency potential in petrochemical plants

Alfa Laval plate heat exchangers are up to five times more thermally efficient than traditional shell-and-tubes. What difference can that make for your plant? Today, the installed base of our plate heat exchanger technologies in the petrochemical industry saves up to 19 TWh of energy – the same amount that it takes to heat nearly 2 million European homes.

Imagine if every petrochemical plant made the switch to more efficient heat transfer technologies today. We could reduce global CO2 emissions by 28 million tonnes, the equivalent of what’s produced each year by the 3.7 million people living in Qingdao, China.

Cutting emissions and boosting capacity

When Dow Wolff Cellulosics encountered an urgent issue with a worn-out shell-and-tube reboiler, they turned to Alfa Laval. We showed them the energy efficient potential of replacing two older units with more efficient plate technologies. The result was an annual energy saving of 22,400 GJ with a 1250-tonne reduction in CO2.
