Vibration is inherent to compressors [...]
When the discharge pressure needed for an application cannot be reached with a single stage gas compressor, a two stage gas compressor is needed. While a two stage gas compressor is more expensive, more complicated to operate, and requires additional equipment, there’s simply no other way to reach a higher discharge pressure if a single stage gas compressor isn’t cutting it.
RoFlo Compressors reviews the compressor comparison between the rotary vane and reciprocating compressors.
The rotary sliding vane gas compressor is a cleverly designed, yet simple machine. It consists of a rotating element (the rotor) inside of a cylindrical casing (the cylinder).
Sour gas is any gas containing significant amounts, typically above 20ppm, of hydrogen sulfide (H2S). H2S is a colorless gas that is heavier than air and harmful to humans at concentrations of 20 ppm in air.
