Title:
METHOD OF HEATING NATURAL GAS IN A CITY GATE STATION
Document Type and Number:
WIPO Patent Application WO2000063621
Kind Code:
A3
Abstract:
A method and system are described for heating natural gas in a station, such as a City Gate station. Natural gas from the field is generally transported via supply line (4) at high pressure to the various distribution networks necessary for delivering the gas. However, before the natural gas can enter these distribution networks its pressure must be reduced to a usable level. City Gate stations employing pressure reducing (JT) valves (16) are usually built for this purpose. The present invention provides a system and method for heating the natural gas, without combustion of the natural gas, by relying on the pre-existing pressure of the gas in the supply line (4) along with particular equipment to provide heat to the gas passing through the station.
