Noise Considerations on Large Process Unit Drivers

The paper deals with typical noise considerations on stem turbines, gas turbines, electric motors, and gears which are used in large compressor drives in the petroleum and chemical industry. The paper considers such things as 1) the factors which contribute to the noise encountered on various drivers; 2) the typical noise levels for the basic drivers for various horsepowers and speeds; 3) various methods of reducing noise on each type of driver; and 4) considerations when installed in the actual plant environment.
