Abstract

Due to an increase of precipitation reactions in water by temperature changes, cloggings canoccur in a geothermal doublet. A consequence of the cloggings is that the process of generatinggeothermal energy becomes inefficient eventually. Our goal is to determine which minerals playan important role in the clogging process in each part of the geothermal doublet. First, we havedivided the geothermal doublet into four tanks. Then we have derived a general model for ageneral chemical reaction. Afterwards, we have used this model for 5 kinds of mineralisationreactions. This led to first-order differential equations, which we have solved analytically ornumerically with the Forward Euler method. Finally, we have concluded that the mineralsbarite, calcite, dolomite and goethite play an important role in the clogging process in tank 3and tank 4.
