| Popis: | The demulsification of orimulsion, an extra heavy crude oil, was studied by a PDY-1 instrument of electric demulsification. Some commercial demulsifiers, including P, RN, and RB series demulsifiers, were tested; however, their dewatering efficiency was unsatisfactory. ZQ series demulsifiers were synthesized and applied. It is pointed out that the ZQX3 series demulsifier had satisfactory dewatering ability for extra heavy crude oil emulsion. In order to improve the dewatering efficiency, toluene diisocyanate (TDI) was used as a chain extender to modify the ZQ series demulsifiers and an assistant—ammonium sulfate (t1)—was added. The results indicate that the dewatering efficiency of ZQ43 and a t1 mixture reaches excellent dewatering efficiency. |
