Experimental setup has been constructed in the laboratory to evaluate the three -phase pressure drop and the hold-up for crudeoil+Water+Gas flow through horizontal helical coils and control valve. This kind of three phase flow occurs in petroleum industries especially in oil rigs where crude oil is explored in bulk quantity. While pumping out crude oil in the oil rig, Not only the crude oil is coming alone, it is mixed with water and natural gas and air. So we have to pump out these three components together. These three components (crudeoil+water+gas) forms three phase flow. That is three immiscible fluids, such a complex mixture is pumped in the oil rig pump and it is transported in pipes to the on shore refinery. Often these pumps are repairing because of air-lock, holdup, and oil leakage in oil seal. So transportation stops, this leads to heavy loss to the oil company.so the pumping system has to be designed carefully with proper controller in this work we have designed an experimental set up of such kind of three phase flow through pipes and helical coil and control valve in the laboratory. Crude oil and water is mixed in a tank by an electric stirrer in a tank and air is injected by compressor, so these three component flow via helical coil and control valve in series, pressure drop is measured across helical coil and control valve for different air flow rate and mixture flow rate By using these data, The flow versus pressure drop chart has been drawn .By linearizing the curve by the second order equation the PID and MPC controller has been designed which is controlling the control valve, By adjusting the opening levels of control valve we can change the flow patterns, crude oil flow rate and maximize the extraction of crude oil exploration from the oil-rig by using minimum of pump energy.
