PERFLUORO PHOSPHATE-TYPE GAS PIPELINE DRAG-REDUCING AGENT AND METHOD OF PREPARING SAME |
摘要 |
The present invention provides a perfluorophosphate-based drag-reducing agent for gas pipelines. Raw materials for the perfluorophosphate-based drag-reducing agent for gas pipelines consist of fatty acid(s), pyridine(s), fluorophosphates(s) and haloalkane(s) in a mass ratio of 2:1:1:1 to 2:3:1:2. A method for preparing the perfluorophosphate-based drag-reducing agent for gas pipelines is also provided. The perfluorophosphate-based drag-reducing agent for gas pipelines is non-toxic and environmentally friendly, has a high drag reduction percentage, a long-lasting effect, good stability and solubility, does not affect the inner surface and coatings of natural gas pipelines or gas quality, and is suitable for on-line atomization and injection. |
