Drag reduction method for gas pipelines
Patent
·
OSTI ID:6350560
This patent describes a method of reducing drag for a gas flowing in a pipeline between a first point and a second point. It comprises: inputting gas at a constant pressure into the pipeline at the first point to establish gas flow in the pipeline between the first and second points; injecting a drag reducer into the gas flow at the first point; monitoring the flowrate of the gas at the second point; and adjusting the injection rate of the drag reducer at the first point until a maximum flowrate of the gas is reached at the second point.
