| Synthesis and Application of Crude Oil Pemulsifier DCN-1 |
| WANG She.（Chemical Engneering Department; Jianghan Petronium institute; Hubei Jinzhou; 434023; China） |
| Abstract：A water-soluble tetrablock-polyether of straight chain structure, DCN-Ⅰ, was prepared for dehydrating high water cut(>80%) viscous heavy crude oil of He-nan produced by steam huff-puff method instead of an oil-soluble demulsifier, KN-1, which became uneffective. The synthesis, performance properties, and field test results at oil-gathering/water-treating plant No 25 of DCN-Ⅰ were presented. With DCN-1 in 80mg/L at dehydrating temperature 70～82℃, qualified crude of water content≤0.50% and separated produced ... |
| Key words：crude oil demulsifier; grude oil dehydration; high water cut viscous heavy crude; synthesis |
