L. Rotating equipment this factor accounts for the hazard arising from the use of large pieces of rotating equipment compressors, centrifuges, and some mixers. [Pg.375]

Centrifugal compressors increase gas pressure by accelerating the gas as it flows radially out from a rotating impeller. The increase in velocity is then converted to increase in pressure as the gas leaves the compression stage. Unlike reciprocating compressors, centrifugal compressors involve a constant flow through the compressor. [Pg.658]

Compressors are rated in feet of compression head developed. This is the energy conveyed to a gas stream by a compressor. It is observed by the increase in gas pressure as the gas passes through the compressor. Centrifugal compressors more nearly follow polytropic operation and are widely used to handle large volumes of gas at pressure ranges of 0.5 to several hundred psi. [Pg.422]

Table 2.8 Revamp options for reciprocating compressors, centrifugal fans, blowers, centrifugal pumps and electric motors.

Centrifugal compressors Centrifugal compressors deliver actual volumetric flows (cubic decimeters per second and performance should not be expressed as mass, mols or standard volumetric flow). Assume compression ratios equal in all stages. Maximum number of stages that can be on one shaft or fit in the frame = 8 minus 1 stage for each side nozzle. Compression ratio 2.5-4. The pressure coefficient = 0.5-0.65 assume 0.55. The pressure differential increases with increase in suction gas density (increased molar mass, suction pressure or decrease inlet temperature, decrease in k). Power up to 7.5 kW/m /s. Efficiency of large centrifugal compressors 76-78%. [Pg.46]
