| Abstract | The geothermal fluid originated from the deep wells in the Italian geothermal fields can be rich in chlorine compounds, and its preliminary abatement, both with in well treatment and with surface equipment, plays a significant role in prolonging the industrial life of gathering systems and turbines. pH control in the discharge of chlorine abatement plants is a key task in the control of plant efficiency and chemical consumption optimization. The high salinity, the presence of hydrogen sulfide and the high temperatures of residual waters prevent adoption of conventional instrumentation. For this reason Enel has built a special assembly capable to adapt high performance pH-meters to chlorine abatement plants. In this paper we report the achievements reached and data of the equipments currently working in more 5 plants. |
