Integrally geared and integrated turbine generator energy recovery for high pressure natural gas
Recovery of pressure let-down energy dates back to the early 1980`s. Several installations have proven the feasibility and attractive pay back of using turbine generator system in lieu of throttling valves. These installations, on average, are saving up to 200,000 barrels of fuel oil per year. Since the first installation, many improvements have been implemented in turboexpander packages and the associated control systems. Based on site requirements, two alternate designs may be introduced. One is a totally encapsulated integral turboexpander generator unit. The other is an integrally geared turboexpander. Both alternatives have the flexibility necessary to cope with a wide range of inlet gas conditions while maintaining required outlet gas conditions. These installations are environmentally friendly (no hazardous gas leakage) and operate within an acceptable noise level.
