Title:
COMBINED EXPANSION POWER SYSTEM APPLICABLE TO ELECTRICITY PRODUCTION FROM HIGH-PRESSURE GAS
Document Type and Number:
WIPO Patent Application WO/2017/067118
Kind Code:
A1
Abstract:
A combined expansion power system applicable to electricity production from high-pressure gas combines piston expanders with radial-inflow turbo-expanders, controls the number of stages of expansion of piston expanders by configuring a gas intake control system of the piston expanders, and improves the efficiency of the piston expanders. The piston expanders and the radial-inflow turbo-expanders are jointly configured; the piston expanders are used for implementing expansion of a high-pressure section, and the radial-inflow turbo-expanders are used for expansion of a low-pressure section. The system makes full use of the overall enthalpy of a high-pressure gas, and meanwhile, the adoption of a reheating process can increase the efficiency of the system. Compared with a common high-pressure gas expansion system where a throttle is used for controlling the intake pressure to be constant, the present system has advantages of large expansion ratio and high overall system efficiency.
