Abstract

Refrigeration is produced while delivering transmission pipeline gas of elevated pressure to a branch pipeline of lower pressure by expanding the gas in a turbo-expander to a pressure below the branch pipeline pressure and recovering refrigeration from the expanded gas which is then compressed by a centrifugal compressor directly driven by the turbo-expander to the pressure required for delivery into the branch pipeline. Preferably, the gas is dehydrated by adding methanol and separating aqueous methanol condensate from the expanded gas, and the condensate is distilled with compression heat to recover methanol for reuse.
