The key to success

Petrochemical , air separation and gas liquefaction units all have one thing in common – they need heat exchangers to process gases and liquids. Coil-wound heat exchangers in particular are used across a broad spectrum of cryogenic applications.

Linde is a leader in this high-tech field, designing and building equipment to match individual customer specifications. To date, the company has successfully delivered more than 1,000 coil-wound heat exchangers (CWHE). These exchangers often weigh as much as 260 tonnes, are up to 7.5 metres in diameter and offer heating surfaces of over 20,000 square metres. Linde can also realise even larger, heavier models on request. What’s more, the company is committed to continually evolving the underlying technologies. For example, to optimise operations and extend lifetime at an LNG plant in Stavanger, Norway, Linde engineered over 4,000 temperature measuring points in the CWHE bundle. This high-precision 3D temperature monitoring capability gives operators an exact overview of the process flow.
