METHOD AND SYSTEM FOR BLENDING GAS STREAMS

摘要

There is provided a method of blending gas streams to produce blended gas, the method comprising the steps of: providing a natural gas stream via a pressure regulator; providing a dosing gas via a dosing gas stream; controlling the differential pressure across the pressure regulator to target a constant flow rate of said natural gas in said natural gas stream; setting a target flow rate of the dosing gas stream relative to the natural gas stream; blending the natural gas stream with the dosing gas stream to produce the blended gas.
