  3. Content • Introduction • Compressor • Function • Type of compressor • Maintenance • Conclusion • Safety

  4. Introduction • Compressor A mechanical device that increase the pressure of a fluid by reducing the volume

  5. Almost similar to pump • Main action pump=pressurize fluid to transport • Main action compressor=pressurize fluid by reducing the volume

  6. Function • Provide high pressure gas to plant • low pressure steam to high pressure steam (steam reforming) • Reduce volume of gas • For transport (LNG) • Processing (Compress gas, increase pressure, increase concentration) • Maintain pressure of gas • Pressurize water in boiler (Carnot cycle)

  7. Function • Cooling/heating system that use refrigerant • Compress gas refrigerant, condensing the gas releasing the heat

  8. Type of compressor • Positive displacement • Compress gas by reducing the volume • Dynamic • Change the velocity of gas to pressure

  9. Positive displacement • Reciprocating • Rotary

  10. Dynamic • Centrifugal • Axial

  11. Maintenance • Preventive maintenance checks • Important • Save time and money • Avoid possible breakdown • Maintains efficiency, saving money, maintaining ouput

  12. Lubrication • Pump oil • Regular checking (Daily) • Oil level • Leak • Oil • Air • Drain water (water vapour in air may condensate when air is compressed) • Belt (timing, power)

  13. Air Filter • Check air filter for dust or breaking (weekly) • Clean or replace • Check to ensure accurate air flow rate • Safety relief valve • Leak

  14. Check (daily weekly) • Noise • Vibration • Connection for leaks • Bolts and screw are tightened • Service pump Oil (Annually)

  15. Cooling system • Compressed gas get hotter • Cooling system for example water cooling system • Gauge • Check and calibrate pressure gauge • Ensure accurate reading • Not overwork/overpressure the compressor

  16. Safety • Before maintenance operation • Ensure all electrical connection disconnected • Ensure compressor is relieved from any pressure • Ensure temperature cooled down

  17. Conclusion • Compressor increase the pressure of gas by decreasing the volume • Two type of compressor design; dynamic and positive displacement • Maintenance important; save money and time for future • Check: lubrication, air inlet, cooling system, gauge, connection, noise, vibration, screw • Safety-disconnect electricity, relieve pressure, cool down temperature
