Title:
ターボ膨張器及び圧縮機入口において可動入口ガイドベーンを使用するための方法
Document Type and Number:
Japanese Patent JP5856765
Kind Code:
B2
Abstract:
A turboexpander-compressor system (200) includes an expander (210) configured to expand an incoming gas (214), a first set of moveable inlet guide vanes (218) configured to control a pressure of the incoming gas, a compressor (224) configured to compress a gas received from the expander (210), a shaft (230) configured to support and rotate an expander impeller (212) and a compressor impeller (226), a second set of moveable inlet guide vanes (232) attached to the compressor (224) and configured to control a pressure of the gas input into the compressor (224), and a controller (240) configured to acquire information about a rotating speed of the shaft (230), a pressure and a temperature of the incoming gas, a pressure and a temperature of the gas output from the expander (210), and to control the second set of moveable inlet guide vanes (232) to maximize a ratio between the rotating speed of the shaft (230) and a drop of an enthalpy across the expander (210), in off-design conditions.
