In order to study the viscous crude oil wastewater, the advantages and disadvantages of various SiO2 removal methods have been compared. It is confirmed that a magnesium compound is added to remove SiO2 chemically. An optimum prescription has been determined through conditional experiments. The results show that the treated water has come up to the standard of boiler feed-water.
Key words： viscous crude oil wastewater; hardness; silica removal; boiler water reuse
