  5. 5. REFINERIES  Barauni Refinery, in Bihar. It was commissioned in 1964 with a capacity of 1 MMTPA. Its capacity today is 6 MMTPA.  Gujarat Refinery, at Koyali (near Vadodara) in Gujarat in Western India, is Indian Oil’s 2nd largest refinery.  Panipat Refinery is the 7th and largest refinery of Indian Oil. The original refinery with 6 MMTPA capacity was built and commissioned in 1998.  Haldia Refinery is the only coastal refinery of the Corporation. It was commissioned in 1975 with a capacity of 2.5 MMTPA, which has since been increased to 7.5 MMTPA.
  6. 6. Barauni Refinery  Barauni Refinery, in Bihar. It was commissioned in 1964 with a capacity of 1 MMTPA. Its capacity today is 6 MMTPA.  Barauni Refinery in the Bihar state of India was built in collaboration with the Soviet Union at a cost of Rs.49.4 crores and went on stream in July, 1964.  Barauni Refinery was built in collaboration with Russia and Romania. It is situated 125 kilometres from Patna.  Barauni Refinery receives crude oil by pipeline from Paradip on the east coast via Haldia.
  7. 7. Highlights of Barauni Refinery:  The establishment of a totally electronic-based communication system within the refinery.  The presence of four ambient air monitoring stations that were in place well before the refinery was in use.  It is an eco-friendly refinery, as indicated by a green belt outside it.  Zero discharge of effluent gases.  It has the lowest manpower of all refineries in the region with similar capacities.
  8. 8. 2. Field Instruments > Pressure Measurement :  Instruments used to measure pressure are called pressure gauges or vacuum gauges.  Pressure gauge performs the mathematical operation of subtraction through mechanical means, obviating the need for an operator or control system to watch two separate gauges and determine the difference in readings.
  9. 9. . 1. Bourdan pressure gauges 2. Diaphragm pressure gauges
  10. 10. Types of Pressure Gauge  Barometer Pressure gauge : It has a glass tube closed at one end, with an open mercury-filled reservoir at the base.  Monometer Pressure gauge : This is the most simple and precise device used for the measurement of pressure.  Capacitive: This is applied measurement of low pressure.  Electromagnetic: It measures the displacement of a changes in inductance, Hall Effect, or eddy current principle.  Piezoelectric: It uses the piezoelectric effect in certain materials such as quartz to measure the strain upon the sensing mechanism due to pressure. This
  11. 11. > Temperature Measurement :  Thermocouples: It consists of two dissimilar conductors in contact, which will produce a voltage when heated. Conductor will experience the temperature gradient, and develop a voltage of its own.
  12. 12.  Thermistors: It is a resistor whose resistance varies significantly with temperature. These are used as in rush current limiters & temperature sensors. Fig: Thermistors  Pyrometer: A pyrometer has an optical system and a detector.
  13. 13. > Magnetic Flow Meter :  The magnetic flow meter A mass flow meter is a device that measures mass flow rate of a fluid traveling through a tube. It requires a conducting fluid and a non-conducting pipe liner. The electrodes must not corrode in contact with the process fluid.
  14. 14. > Level Measurement :  Radar : Radar is an object detection system which uses radio waves to determine the range, altitude, direction, or speed of objects. It is mounted on the top of the vessel.  Ultrasonic : In this method ultrasonic sound waves are used in place of radio waves. It also works on the basis of Doppler Effect for level measurement.
  15. 15.  Capacitive : In this method, the property of a capacitor is used that the capacitance of the capacitor changes when a dielectric material (medium) is introduced between its two plates. The capacitance of the capacitor is directly proportional to the level in the vessel.
  16. 16. > Control Valves:  A valve is a device that regulates, directs or controls the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing various passageways.  Valves are found in every industrial process, including water & sewage processing, mining, power generation, processing of oil, gas & petroleum, food manufacturing, chemical & plastic manufacturing and many other fields.
  17. 17. Components of Control Valves:  Air Filter Regulator (AFR): It filters the air & removes the small unwanted dust particles. The filtered air can also be regulated with the help of AFR.
  18. 18.  Positioner: This is used for position control. It receives air from AFR & it also receives a signal from control room. Positioner supplies that amount of air to the valve which fulfills the control room demand.
  19. 19. 3. Process Control & Monitoring: > Distributed Control System (DCS):  DCS (Distributed Control System) is a computerized control system used to control the production line in the industry. The entire system of controllers is connected by networks for communication and monitoring.  A DCS typically uses custom designed processors as controllers and uses both proprietary interconnections and communications protocol for communication.  DCSs are connected to sensors and actuators and use set point control to control the flow of material through the plant.
  20. 20.  DCSs may employ one or more workstations (FCS or HIS) and can be configured at the workstation or by an off-line personal computer.
  21. 21. >Programmable Logic Controller (PLC):  A Programmable Logic Controller, PLC is a digital computer used for automation of electromechanical processes.PLC is designed for multiple inputs and output arrangements.  It is also called Programmable Controller.  It performs sequential relay control, motion control, process control, distributed control systems and networking.
