Abstract
An instrument air system and method is disclosed herein. The instrument air system includes a shaft-driven air compressor configured to generate instrument air by compressing atmospheric air, a power take off configured to derive drive torque from a driven rotary shaft of the process, wherein the power take off may include a concentrically-mounted clamping collar adapted to frictionally engage the driven rotary shaft, a torque-transfer assembly configured to transfer the drive torque derived by the power take off to the shaft-driven air compressor, wherein the torque-transfer assembly comprises a set of interoperating gears including a ring gear operably coupled to the clamping collar, and an instrument-air pathway configured to supply the instrument air generated by the shaft-driven air compressor to the pneumatic process-control subsystem. The instrument air system and method is useful for reducing hydrocarbon emissions of a process using a pneumatic process-control subsystem.
