The North China heavy oil was measured using a digital display viscometer produced by Brookfield Co. The 5% polyether carboxylic acid–sulfonate solution was mixed with North China heavy oil in the ratio of 1:1 by volume, heated at a water bath temperature of 50 °C for 15 min, and stirred with an emulsifier (D-160) at a speed of 8000 r/min for 4 min. The emulsion layer viscosity was measured at that temperature after standing for 1 min. At the same time, an equal volume of heavy oil was taken under the same conditions to determine its viscosity as a control group.

The viscosity was determined by using the digital display viscometer produced by Brookfield Co. (Toronto, ON, Canada). The viscosity was determined by mixing 25 mL of 0.5% polyether carboxylate solution with North China heavy oil in a ratio of 1:1 by volume, heating in a water bath at 50 °C for 15 min, stirring with an emulsifier (D-160) at 8000 r/min for 4 min, and then standing for 1 min to determine the viscosity at that temperature. An equal volume of heavy oil was taken under the same conditions to determine its viscosity as a control group.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
