ValveMechanical device specifically designed to direct, start, stop, mix or regulate the flow, pressure or temperature of a process fluid

Pump, Compressor, Fan & BlowerPumps:•A pump is a machine for raising a liquid - a relatively incompressible fluid - to a higher level of pressure or head.Compressors:•A compressor is a machine for raising a gas - a compressible fluid - to a higher level of pressure.Blowers:•A blower is a machine for moving volumes of a gas with moderate increase of pressure.Fans:•A fan moves large amounts of gas with low increase in pressure.

PFDA process flow diagram (PFD) is a diagram commonly used in engineering to indicate the general flow of plant processes and equipment. The PFD displays the relationship between major equipment of a plant facility and does not show minor details such as piping details and designations.

P&IDA piping and instrumentation diagram/drawing (P&ID) is a diagram in the process industry which shows the piping of the process flow together with the installed equipment and instrumentation.

Process ControlRefers to the method that are used to control process variable when manufacturing product

Why control is necessary?1.Safety2.Environment protection3.Equipment protection4.Smooth plant operation & production rate5.Product quality6.Profit optimization7.Monitoring & diagnosis
