Multi-Stage Separator Apparatus

Manufacturer: Vinci Technologies
Model Number: MSSA

This equipment is designed to simulate a full-scale field separation unit. It is used to determine the optimum conditions of separation by calculating the changes in formation volume factor and gas-oil ratios with changes in separator pressure and temperature. A reservoir fluid sample is brought at its bubble point pressure and reservoir temperature in a PVT cell. A known volume of this sample is then transferred into the separator cell at separator conditions of pressure and temperature. As a result of these thermodynamic changes, gases evolve from the liquids. The volumes of liquid and gas are measured at the separator conditions and the gas released is also measured by a gasometer at standard conditions. The separator test is usually carried out at a number of separator pressures in order to determine the optimum field separator conditions. The final step is carried out at atmospheric pressure. The main parameters which are determined by the experiments include the formation volume factor, the separator volume factor and the solution gas-oil ratio.
