Abstract: Using key thermodynamic properties, the performance of a multi-phase desander deployed to separate solids from crude oil stream could be monitored to ensure effective solid-liquid separation operation. Studies have been done using temperature and flow rate as operating parameters, separately, to monitor performance of multi-phase desanders. In this work, pressure is considered as the operating parameter and the control process using Differential Pressure Cell (DPC) as the controller mechanism. Using a Proportional Integral Derivative (PID) process controller, the performance of the desander was monitored. The work involved the simulation of the solid-liquid separation process of a crude oil stream with the multiphase desander operating at 12bar pressure, and results achieved showed separation efficiencies of 58% to 100% for particle sizes of between 15 µm and 75µm. The results achieved showed that with PID values of 0.66038, 0.78599/s and 0s, the operation attained stability in 5.53s in the automatic mode, whereas in the manual mode operation, stability was achieved after 7.96s with PID values of 13, 8/s and 7s manually selected. The rise time of the PID pressure controller in automatic mode was 1.35s and in the manual mode of operation it was 0.213s.
