Berglunds Rostfria, which produces pressure vessels, heat exchangers, and similar products in corrosion resistant materials, has its sights set on Statoil's Snøhvit project. The Norwegian oil company already figures on the company's reference list – early this year it completed delivery of three degassing vessels, one for each of the Gullfaks platforms.
The vessels, which are almost identical, are made of 2205 duplex stainless steel. Each is 2 m high, with a diameter of 600 mm, a weight of around 1 tonne, and with the capacity to handle up to 350 kg/hr of liquids and 50 kg/hr of gas. The order for the vessels came through platform contractor Fabricom.
Berglunds has joined forces with the Arctic Suppliers, a group of some dozen northern Norwegian and northern Swedish companies formed specifically to seek orders for Snøhvit.
The company has one product of its own, a lamella heat exchanger. The lamella element consists of two thin metal strips welded together in pairs along the edges a short distance apart. A number of lamella elements are stacked in a bundle, thus forming channels both within each pair and between each pair.
This design offers a number of benefits, Granberg says. A high degree of heat recovery can be achieved, and it is more efficient in some applications than conventional heat exchangers. It is also compact – allowing it to be installed in relatively small spaces – and lightweight, due to its low retention volume. ;
