Thermal Conductivity of Ternary Aqueous H2O + Li2SO4 + Zn(NO3)2 Solutions at High Temperatures and Pressures

“…A geothermal brine is a complex aqueous solution containing varying amounts of dissolved solids (ion species) and gases. Li 2 SO 4 and Zn­(NO 3 ) 2 are one of the main components of geothermal fluids (see, for example, refs –). The major mineral components (dominant ions) in geothermal fluids − are Na + , K + , Ca + , Mg + , Li + , Zn + , S + , Si + , B + , Se + , Sr + , Mn + , SO 4 –2 , Cl –1 , NO 3 –1 , etc.…”
