Abstract

Language:

Volatile chloride (HCl) is found in geothermal fluids all over the world, and when dry steam containing HCl cools to its acid dew point, the compound dissolves in the condensate and forms hydrochloric acid, which can cause severe pitting corrosion in piping and equipment. This study focuses on the Icelandic Deep Drilling Project (IDDP), which deals with high enthalpy, HCl-laden geothermal steam, highlighting the need for effective corrosion mitigation strategies to enable the feasibility of utilizing this resource. Several methods for HCl removal from geothermal steam were explored, emphasizing the importance of energy conservation in their applicability. Additionally, the research analyzed how different corrosion mitigation methods perform as the enthalpy of the geothermal fluid increases. This analysis is integral in addressing the operational challenges posed by corrosive geothermal environments and optimizing the management of high-temperature geothermal power plants.
