Abstract:

The preparation of a new-type of water purifying agent is introduced. Infrared spectrum and thermo-gravimetric analysis have been used for analyzing the structure and thermo-stability of the new-type of water purifying agent. When the self-designed equipment, which can evaluate the oil-removing capacity of water purifying agent, under high temperature and high pressure conditions，is used for treating the SAGD produced water which is highly oilbearing and has extra-heavy viscosity, the oil-removal efficiency of the new-type of water purifying agent under different conditions is investigated. The results show that the product has very good thermo-stability and both of the oil removal efficiency and oil removal speed are satisfactory. The oil remove rate could be higher than 99％.
