Silica Precipitation and Scaling in a Dynamic Loop System

摘要

A titanium corrosion test loop was modified to provide a dynamic facility for studying the formation of silica precipitates and scale from simulated geothermal brines as a function of composition, temperature, and flow conditions. A schematic of the modified loop system is presented. The principal components and connecting piping are all constructed of commercially pure titanium. These components include a centrifugal pump, silica saturator column, segmented heat exchanger, reheat heat exchanger, and a high pressure feed pump (stainless steel). The system is designed to circulate simulated geothermal brines saturated with silica to approximately 300 exp 0 C for study of silica scaling. Data obtained from a test run are included.
