What is The Solubilities of Phosphate and Sulfate Salts in Supercritical Water about?

Inorganic compounds are regularly present in aqueous streams. To understand their influence and behavior on these streams at supercritical conditions, little to no property data is available, which can be used as starting point for further research or application design. Since inorganic compounds tend to precipitate at these conditions, scaling, blocking and erosion can occur as a consequence. Furthermore, a separation of (precious) compounds from the bulk stream due to the precipitation is possible. Here, phosphate compounds are regarded as interesting for further investigation since resources are assumed to be depleted in future. As phosphate is present in many waste streams, these could be used as sources for recoverable phosphate. Resulting from these facts and options, a proper understanding and knowledge of these systems is important for later industrial applications. Therefore, the authors have investigated the behavior of salts (e.g. NaCl, NaNO 3 and MgCl 2 ) in supercritical water in previous works. To extend this knowledge, the solubilities of the sulfate salts MgSO 4 and CaSO 4 in a range of 18.8-23.2 MPa and 655-675 K as well as of the phosphate salts Na 2 HPO 4 , NaH 2
