Abstract

A geothermal energy source is one of the wealth of mineral resources that are being widely used. Geothermal Power Plant is a solution to the needs of New Renewable Energy to overcome energy needs and dependence on renewable energy. However, there were important problems that occur in the geothermal field, namely the formation of silica scaling in the production pipe causing the brine injection process to be disrupted, the injection process aims to maintain the volume of the geothermal reservoir and maintain the quantity of producing steam in the long run. Therefore, controlling silica in the brine injection path in geothermal fields is very much needed. This paper discussed the decrease in silica mass influenced by pH and the addition of Sodium Lignosulfonate (SLS) surfactants that studying the changes in pH (7, 8, and 9), and surfactant concentrations (0.05, 0.15, and 0.30% (w/v)). The results showed that the dissolved silica in the geothermal solution was reduced and could be controlled by the addition of SLS surfactants. The greater the surfactant concentration and pH, the more the mass of silica will be taken. The best conditions are at pH 9 and SLS surfactant concentration 0.30%w/v. Keywords: geothermal, silica scaling, sodium lignosulfonate, surfactant.
