Certain Investigations on Various Optimal Control Techniques for Energy Saving in Flow Process Station

Abstract

In current years energy saving has become imperative in industrial system including liquid transfer and hydraulic processing In addition there is an enormous demand for cost saving of flow process in industries The flow process station FSC comprises of the following components i A reservoir It is from the reservoir by means of a motor the liquid is transferred to the overhead tank ii The process variable The flow of the liquid is the processes variable iii An orifice meter This measures the rate of flow of liquid passing through the pipe iv Differential Pressure Transmitter DPT This module has a threefold activity where the pressure difference is sensed calibration is done to provide the required correct flow and provides the process computer PC the measured value of flow The main role of the PC is to detect error control the flow and sent the error signal to the IP converter. The IP converter by varying the position of the stem of the control value controls the flow of the liquid in the pipeline The present arrangement of flow control station comprises a control valve which throttles the liquid stream in the pipe as per the control standard given by the controller Flow process station finds its application globally in various fields of science and technology especially where liquid flow happens namely oil and gas industries chemical and food production plants In the recent past few decades there is an exponential increase in the adaptation of variable voltage control VVC and variable frequency control VFC methods wastewater transport systems. newline
