The automation process of oil and gas refinery process is an important role in providing security for workers, play the precision in the control of machines and the reduction in the workforce. Oil industry and refinery gas is mostly manual system with many risks, such as explosion hazards, fire hazards and lightning, radiation, etc. The industry of many of these processes is controlled in a conventional manner or a conventional control via DCS. Automation is the area safe, sturdy, economical and highly efficient and maintenance-free. The structure and the implementation of a specific SCADA / PLC are correct in an oil refinery process introduced. It consists of seven main units make: Oil drilling unit, separating plants, oil production units and gas, refineries, and storage units and the control unit. The products from the process petroleum refining come to in our daily lives with liquefied petroleum gas (LPG), naphtha, gasoline, kerosene and diesel, which have been widely used. The construction of a highly stable and reliable SCADA / PLC instead of DCS must identify the management and control of the automatic oil refining.
