Process for treating geothermal brine in two phase brine separators
This paten describes a process for treating hot, pressurized silica-rich geothermal brine in a bring liquid-vapor phase separating vessel having a draft tube therein with a steam outlet port thereabove, the process comprising: providing a liquid level of up to 2 feet above the top of the draft tube, by, introducing hot, pressurized silica-rich geothermal brine into the brine liquid-vapor phase separating vessel draft tube; reducing the pressure of the hot, pressurized silica-rich geothermal brine within the brine liquid-vapor phase separating vessel to cause boiling of the hot, pressurized silica-rich geothermal brine and the generation of steam; introducing a seed material into the brine liquid-vapor phase separation vessel for causing the precipitation of silica onto the seed material; reducing the formation of silica scale buildup on interior surfaces of the brine liquid-vapor separating vessel and substantially increasing the production rate of steam generation by maintaining the brine level substantially above a top of the draft tube through contacting the hot, pressurized silica-rich geothermal brine with a defoaming agent.
