Utilization of the chloride bearing, superheated steam from IDDP-1

Abstract

When a dry steam containing volatile chloride cools to saturation temperature, the compound dissolves in the condensate and forms hydrochloric acid. This can have tremendous consequences for equipment as hydrochloric acid aggressively attacks steel and other metals, causing severe pitting corrosion, crystalline corrosion and stress corrosion cracking of stainless steel components. The Icelandic Deep Drilling Project is dealing with extreme circumstances with high enthalpy, superheated steam possibly containing hydrogen chloride. Successful corrosion mitigation is essential for the feasibility of the development. The goal of this work is to examine different technologies to utilize such a steam, with regard to exergy conservation. © 2013 Elsevier Ltd.
