A new heat exchanger for LPG/E cargo condensers

DuroShell (photo) is a specially engineered plate-and-shell heat exchanger with unique design capabilities. Already used in the offshore oil-and-gas industry, it is now being introduced for demanding marine duties such as LPG/E (liquefied propane gas and ethane) cargo reliquefaction. An innovative construction and a patented roller-coaster plate pattern make DuroShell significantly more robust, allowing it to condense cargo with a higher ethane content. DuroShell withstands pressures up to 35 bars when titanium plates are used, along with temperatures as low as –198°C. — Alfa Laval AB, Lund, Sweden
