Abstract

In order to study the problem of scaling in pipeline during the development of hydrothermal geothermal resources, geothermal water in Fengshun area is selected as the research subject. The scaling tendency of geothermal water was analyzed through the analysis of water quality and scaling components, and the best scaling inhibitor was selected. The Larson index (LI) and Ryzner index (RI) analysis showed that the geothermal water has a slight scaling tendency. The results of XRD and Micro-CT showed that the main content is CaCO3 (99.8%). PASP and PESA were chosen to conduct scaling inhibition analysis. At 90°C and 8 h, the scaling inhibition rate of PASP and PESA can reach to 91.3% and 90.1% at the concentration of 15 mg/L, which can meet the practical demand. In view of the high price and poor economy of PASP, it is suggested that PESA be chosen as the green environmental protection scaling inhibitor for this type of geothermal water.
