Global warming and greenhouse gas emissions are a great concern. To reduce these emissions, there is a global trend towards cleaner energy sources.
There are two compressors with two different coupling, the first coupling with a gas turbine and the second coupling with an electric motor, the gas turbine functions by the combustion of fuel gas causing greenhouse gas emissions and noise pollution, contrary to that, the electric motor is not polluting like the turbine, it is for this reason that we made a comparative study between the noise generated by the turbo-compressor and that generated by the motor-compressor.
These latter machines are among the first sources that cause the problem of noise of industrial origin, several studies have been carried out in the world to treat the industrial noise problem.
Several origins of noise can be distinguished in the turbo compressor system:
- It’s evident that a small fraction of this energy is converted to an acoustic energy, it can propagate into the whole system and be manifested as noise, and the vibration of the body can also contribute to the generation of noise.
- The vibration of the compressor’s components or surfaces because of the variations of the pressure generated in the fluid.
- The unbalanced rotors, the rubbing of the shaft, the partition of the vibrating pipes.
