TURBOEXPANDER OPERATING PROCESS

FIELD: expanding natural gas for various purposes. SUBSTANCE: natural gas is supplied at high pressure from line 1 to turboexpander 2 wherein it is expanded and its temperature is reduced. At outlet of turboexpander 2 natural gas is heated in heat-exchange apparatus 11 due to heat released by coolan...

Beschreibung
Zusammenfassung:	FIELD: expanding natural gas for various purposes. SUBSTANCE: natural gas is supplied at high pressure from line 1 to turboexpander 2 wherein it is expanded and its temperature is reduced. At outlet of turboexpander 2 natural gas is heated in heat-exchange apparatus 11 due to heat released by coolant coming from refrigerant user 12 as well as in heat-exchange apparatus 14 due to heat released by compressed air coming from air compressor 4. When bladed machine 4 mechanically coupled with turboexpander 2 runs as pump, natural gas is additionally heated in service tank 9. EFFECT: improved operating reliability of turboexpander. 1 dwg
