Silica in boiler water | Emerald Insight

Abstract. Steam assisted gravity-drainage (SAGD) is a method to produce bitumen or extra-heavy oil by injecting steam into the reservoir. The steam lowers the viscosity and the mixture of oil and water are then able to flow through production well. After separating produced water and oil, the water is recycled to the steam generation system for

Silica Scaling in Boilers - Lenntech

Silica content of the boiler water is critical for steam turbines and scaling of boiler heat transfer surfaces. Silica (SiO 2) can volatilize with the steam in sufficient concentrations to deposit in steam turbines leading to scale formation on boiler surfaces. In this work, a simple correlation is presented to predict silica (SiO 2) solubility in
