METHOD FOR OPERATION OF TURBO-EXPANDER PLANT Russian patent published in 2000 - IPC

FIELD: turbo-expander plants. SUBSTANCE: before the turbo-expander high-pressure natural gas is additionally separated into two parallel flows-ejecting natural gas and natural gas expanded in the turbo-expander. Ejecting gas is directed to the main with a control member and active part of the ejector. Natural gas past the turbo-expander is directed before mixing with natural gas past the pressure regulator to the ejector passive part, and natural gas flows past the pressure regulator and past the ejector are mixed in the user's main. A pump is used as the turbo-expander power load. The pump working fluid is directed to two parallel circuits: a closed hydraulic circuit conjugate to the power-and-heat supply system and an open hydraulic circuit for supply of the hydraulic turbine. EFFECT: enhanced reliability and efficiency. 1 dwg
