L.A. Turbine completes design of a Nitrogen Turboexpander
January 2010
Valencia, CA – L.A. Turbine has completed the design phase of a small Turboexpander. The Frame L1000 Turboexpander –Compressor will be used for Nitrogen Service in Poland. This machine is mounted on a single skid with its own pressured auxiliary system.
This machine was designed by L.A. Turbine’s highly skilled and experienced engineering team, making use of state-of-the-art technology. Using this technology, the L.A. Turbine design team was able to create and use a 3-D virtual model to simulate all potential operating conditions, before the machine was even built.
This machine will feature L.A. Turbine designed inlet guide vanes. The nozzles are matched to the expander wheel inlet such that from minimum to maximum flow the optimum velocity vectors and maximum machine efficiency are obtained. L.A. Turbine uses a low friction coating on the contact surfaces of the nozzles between the adjusting and fixed ring to increase the reliability and life of the nozzle assembly. The most prominent feature of L.A. Turbine’s nozzle assembly is that there is no blow-by of the nozzles and thus no loss of efficiency. This accomplished by optimizing the trade-off between clamping force and potential blow-by. A pneumatic/electric nozzle actuator with positioner and a hand-indicating controller allows for precise nozzle adjustment.
