A microwave apparatus for phase boundary determinations of corrosive fluid mixtures to 1.7 kbar and 588 K is described. The apparatus measures shifts in a static microwave energy field caused by changes in sample dielectric properties. The measured interactions involve the entire sample cell; sample volumes are small (∼25 cm3); phase transitions are measured directly. Details of the microwave apparatus and the microwave technique are discussed. Data are presented for pure fluids and for an acid-gas/heavy oil mixture that demonstrate the performance of the apparatus.
