Abstract
The presence of in geothernial steam cause generalized corrosion in trasportation pipelines and stress corrosion cracking of turbine blades. This led to tlie practice of steam washing with alkaline solution when the chloride ion exceeds 15-20 ppni. present paper results obtained in a pilot plant operating with fluids are used to design an absorption column operating cocurretit flow. Tlie design procedures which have been developed take into consideration the simultaneous heat transfer process and an attempt is made to the power losses related to washing operation.
