During geothermal energy use serious difficulties are faced due to scaling
from geothermal fluid. The first step to avoid these problems is studying a
nd modelling scaling processes. A computer modelling program has been devel
oped and a laboratory scale device was constructed to test the program. Thi
s equipment was suitable to determine experimental conditions of equilibriu
m solubility investigations before the construction of a pilot-plant scale
modelling equipment. Solubility-scaling investigations were also scheduled
in the pilot-plant scale equipment with the help of these experiments.
