R&D News: Vahterus Test Lab is the Coldest Spot this Winter

Vahterus is currently undertaking an interesting series of tests. Earlier tests have focused on high temperatures, phase-changing phenomena and fluid hydraulics. This time, Vahterus test lab personnel are conducting larger series of cryogenic tests. Using liquid nitrogen at temperatures of -180C, it is possible to test our heat exchangers in an environment that is equal to or even more challenging than normal LNG vaporizing conditions.

The aim of this large test series is to further understand the special features of heat transfer with cryogenic fluids. Demand for cold recovery in LNG applications is pushing systems to provide brine temperatures that are increasingly close to freezing. Vahterus is therefore studying the behaviour of glycol and other brines close to freezing point.
