DRAG REDUCTION METHOD FOR GAS PIPELINES |
摘要 |
<p>A method of reducing friction or drag on a gas, e.g. natural gas, flowing in a pipeline wherein a drag reducer is injected into said pipeline to form a thin film on the internal surface or wall of the pipeline. The drag reducer in the present invention is selected from a class of chemical compounds which are comprised of a molecular structure having a polar group at one end thereof which bonds onto said inner wall of the pipeline and a non-polar group at the other which smoothes the gas-solid interface between said wall and said flowing gas thereby reducing gas turbulence at said interface.</p> |
