CASE 9 USE OF MAGNETIC BEARINGS BY NORSKE SHELL IN AN ONSHORE APPLICATION... 

However, each application has its challenges. What made Norske Shell s application so different from other turboexpander units using magnetic bearings was the combination of power level and speed 6,000 kW (8,046 hp) on each shaft at 7,000 rpm, with typical pressures of 90 bar (1,305 psi). 

Because Norske Shell was using these turboexpanders in a dewpoint control process, it was necessary to factor in other specific conditions. For instance, these mrboexpanders could be exposed to possibly violent process transient conditions. For this reason, the magnetic bearings required a flux control system to increase the response capability, which was developed by the original equipment manufacturer in concert with the magnetic bearing manufacturer. The load factor of... 

A 250 kilowatt system is planned for a site in Norway. The system will be operated by Norske Shell to demonstrate that CO2 can be economically recovered. The CO2 recovery technology is being developed by Shell Hydrogen. The CO2 could be sequestered in underground reservoirs or could be used for special applications such as fish farms or agricultural greenhouses. The test system will be sited at a fish hatchery. The system is expected to begin operation in early 2003.
