Heat recovery in a paraxylene plant in Asia - using process energy the smart way
Exchanging the existing air-cooled condensers for four Compablocs allowed a major paraxylene producer in Asia to increase heat recovery by more than 23 MW in its plant.
DATE 2023-11-28The company is constantly looking for new ways of improving energy efficiency. When its engineers learned about the benefits with Alfa Laval’s compact heat exchangers they saw new possibilities for large energy savings.
Compact heat exchangers
Alfa Laval’s compact heat exchangers offer much higher thermal efficiency then traditional shell-and-tubes, making them much smaller. They have a temperature approach as small as 2°C (3.6°F) and can operate with a crossing temperature program, allowing for more heat recovery and at a lower temperature.
Compact heat exchangers open up new possibilities for recovering heat that has previously been regarded as waste.
The compact, fully welded Compabloc heat exchanger is designed to operate with a wide range of aggressive media and at high temperatures and pressures.
