Silica removal

A comprising thermodynamic approach is presented to investigate the behavior of saline solutions with respect to CaCO3, CaSO4 and SiO2 scaling in water treatment processes. The Pitzer activity coefficient model is used to describe the aqueous species activities and the corresponding equilibrium reac

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 pro
