Carbon dioxide seize and garage (CCS) is a know-how geared toward lowering greenhouse fuel emissions from burning fossil fuels in the course of commercial and energy-related tactics. CCS contains the catch, delivery and long term garage of carbon dioxide, often in geological reservoirs deep underground that will rather be published to the ambience.

After synchronous speed is reached, motor speed is independent of load, up to the pull-out point, as shown in Figure 3-12. The Page 37 Figure 3-8 Relationship of Current, Voltage, and Power in Resistive and Inductive Loads Fairbanks, Morse & Co. Page 38 primary difference between induction and synchronous motors is that the rotor field coils of the synchronous motor are supplied with a separate dc excitation current rather than relying on slip-generated current. The synchronous motor normally has a small inductive component on the rotor to enable motor starting since the pure synchronous motor has zero torque at rest.
Type are lower initial cost, lower installation and maintenance costs, reduced vibration, smaller size, and delivery of uniform, minimally pulsing air flow. The double helical screw units are available in oil flooded and nonlubricated designs, the lubricated ones being more efficient and less costly to purchase and operate. The oil flooded design is illustrated in Figure 3-4A. Air is compressed by the two rotating, intermeshing rotors. The action of the rotary screw can be compared to a reciprocating compressor.
Plant air systems operating at 100 psi normally require two or more stages of centrifugal compression, all stages normally driven by one large bull gear. Figure 3-5 illustrates a typical three-stage centrifugal compressor. The basic element of the centrifugal compressor is an impeller, which is mounted on a shaft and positioned within a housing consisting of an inlet, a volute, and a diffuser. The impeller spins at high speed and imparts a velocity to the air. The diffuser surrounds the impeller and acts to convert the kinetic energy of the air into potential energy at a higher pressure level.
