Supercritical point drying process
WebIn the present embodiment, the drying unit 16 dries the substrates WF one by one by a method called “supercritical drying” (SCD). In this supercritical drying process, the rinse liquid 221 that remains on the surface S1 of the substrate WF is replaced with a water-soluble organic solvent, such as isopropyl alcohol (IPA), and then this water ... WebSCWO is a process for total oxidation of wastewaters that takes place above the critical point of water that is 374 °C and 22.1 MPa. Water polarity changes as a function of temperature and pressure. In this way, at supercritical conditions water is a non polar solvent completely miscible with organics and gases like oxygen [2]. Under these ...
