Cryo AB

Sweden’s first LNG terminal is located in Nynäshamn, nearby Nynas AB’s refinery. The facility consists of a jetty, a 22 000 m³ storage tank, process equipment and loading areas for trucks.

Condensed natural gas is called LNG (Lique­fied Natural Gas). At -162 °C natural gas is condensed to liquid, while the volume beco­mes 600 times smaller. Natural gas replaces oil and gas as fuel for industry and shipping and is from the energy point of view the same as biogas. Natural gas can be considered the most environmentally friendly fossil fuel, because it has the lowest CO₂ emissions per unit of energy and little or no sulfur.

Caverion has awarded a number of contracts as a main subcontractor in several projects.

Cryo AB is one of the world’s leading manufacturers of cryogenic equipment for the storage, transportation and handling of liquefied gases. As part of the Linde Engineering Division, Cryo AB combines over 50 years’ experience with advanced technologies to the benefits of its customers. The expertise scales across the entire handling chain – from certified tanks through storage stations to full-blown LNG terminals.
