Spiral heat exchanger solves costly fouling problems

A major US refinery was experiencing severe fouling and plugging problems in two shell-and-tube heat exchangers installed to cool desalter effluent using cooling water. In 2008, on Alfa Laval's recommendation, the refinery replaced the two shell-and-tubes with a fouling resistant spiral heat exchanger. The result exceeded expectations.

DÁTUM 2022-02-03

The spiral heat exchanger gives continuous problem-free operation, higher process reliability and more consistent wastewater treatment temperatures than the shell-and-tubes. Best of all, there has been no plugging and, based on savings in maintenance and cleaning costs alone, the payback time was less than 18 months. The on-site engineers were delighted! As one remarked: “I think the technology is great!”

Az Alfa Laval spirál hőcserélőket a hőátadás során előforduló legnehezebb kihívások kezelésére - például a szennyezett közeg okozta gyakori eltömődés, valamint a nyomásesésből fakadó vagy a helyszűke miatt fellépő problémák megoldására - tervezték.
