The purpose of this work has been to perform numerical calculations on the cubical mixing tank the QB mixer, to be able to verify its strength and try to improve it. The QB mixer is produced by the company QB FoodTech AB. Firstly a CAD model was made from drawings of the mixer. Then the structure was analysed in aspects of pressure load, thermal loads and gravitational load. A modal analysis to ge

The task consisted in helping Tetra Pak with the problem that they today have with unexplained deformation of their creasing carriages. Tetra Pak uses different carriages depending on which kind of packaging that is to be manufactured. The carriages are hauled in and pulled in to the production line when another type of packaging is to be manufactured. Basically the carriages look the same, the th

Frågeställningen är vad som krävs för att göra denna implementering lyck

Power production represents one fourth to one third of all CO2 emissions. Carbon Capture and Storage (CCS) in one way to approach the increasing problem with CO2 emissions from fossil fuelled power plants. The CO2 is separated, compressed and transported to a final storing site. To allow more efficient transport and to match the pressure of the final storing site, the CO2 is compressed to a superc
