Abstract

Summary An interactive program (PVTLAB) was written to simulate PVT experiments with a microcomputer. The simulator is a real-time representation of an actual PVT laboratory. Operations typically performed in the laboratory may also be performed with the simulator. The Peng-Robinson equation of state (PR-EOS) is used to calculate phase behavior, and the results of the calculations are displayed in color on the microcomputer monitor. The monitor graphically represents the condition of all the physical components of the PVT laboratory, including pressures, fluid levels in vessels, and the status of valves and pumps. A printed record of every action taken during a run is kept if desired. A simulated experimental error results in an appropriate termination of the run. Program structure and operation are described, and examples of simulated PVT experiments are given.
