Objective
The research program includes low- and high-enthalpy geothermal exploitation. Its objectives are:
- Understanding of the physical and chemical processes of corrosion and scaling in geothermal installations;
- Modelling of these phenomena;
- Definition of new methods for investigating and combating corrosion and scaling.
The project is divided between the participants in the two branches of high- and low-enthalpy.
For the low-enthalpy field the programme will include:
1) Analyzing the mechanism, under different conditions of exploitation, of corrosion and scaling with the formation of iron sulfide. This study requires: a) the development and use of a new and specific bottom-hole sampler; b) laboratory tests; c) new numerical models.
2) Analyzing the influence of sulphate-reducing bacteria producing H2S and also the procedures to combat them.
3) Studying and testing special anti-corrosive methods : a) organic inhibitors (including solid state); b) mineral inhibitors; c) sulfide oxidation.
For the high-enthalpy field the program will include:
1) Improving the understanding of two-phase flow geothermal systems;
2) Determining the significance of various factors that favour scaling;
3) Studying coagulation of colloidal sulphide and silica particles and the possibility of separating them;
4) Studying new methods for separating non-condensible gases from steam;
5) Studying the mechanisms of calcium-carbonate and iron-sulfide scaling and their relationships;
6) Examining the relationship between scaling and corrosion;
7) Studying the mechanisms and controls of chloride corrosion by : a) analysis of droplet condensation from wet steam in long pipes; b) laboratory studies of steam and gas cleansing.
