New findings in desalination described by Y.B. Zeng and co-researchers
January 7th, 2008
According to recent research from Wuhan, People's Republic of China, "This work developed a new treatment system, which could effectively reduce silica in heavy oil produced wastewater to the acceptable levels in the reused boiler at the Xinjiang oilfield. With this treatment system, the harmfulness of silicate scale to the steam boiler run could be reduced in the production of the oilfield."
"Some chemical clarification methods for silica removal were compared. The combination of magnesium compound, sodium hydroxide precipitation and zinc sulfate coagulation was investigated to control the silicate scale. The results indicated that silica was removed mainly through...
