摘要： The present invention provides a method and apparatus for generating refrigeration in a process operating at sub-ambient temperatures in which the refrigeration is generated by a turboexpander. The turboexpander is coupled to a generator controlled so that its speed is maintained at a setpoint through electromagnetic braking and its power output is maintained at line matching voltage and frequency. The speed control of the generator therefore, also controls the speed of the turboexpander. The setpoint is calculated to be equal to a product of an operational efficiency parameter, U/Co, and a square root of twice the enthalpy drop in the flow passing through the turboexpander divided by a product of pi and a diameter of an impeller employed within the turboexpander.

摘要： A cryogenic turbo-expander has a rotary shaft which carries a turbine wheel and carries or is operatively associated with an energy dissipating device and which extends axially through a sleeve. Two sets of bearings, which are housed by two races surrounding the shaft, are axially spaced from one another. Each race has an aperture therein extending from an outer to an inner surface thereof communicating with a lubricating oil passage extending from an outer surface to an inner surface of the sleeve. Both races are arranged so that spent lubricating oil can pass therefrom to a common drain passage. The cryogenic turbo-expander additionally includes a reservoir for lubricating oil communicating with the aperture in the first race via an intermittently-operable metering pump and with the second race via an intermittently operable metering pump.
