The problem: A piston-type reciprocating compressor has had valve damage, or the valves just are not sealing for some reason. This low-temperature refrigeration system has a thermostatic expansion ...

Diagnosing a faulty compressor valve is something HVAC technicians have to deal with on a semi-regular basis, and while a bad valve is often not the main reason a compressor fails, it is an integral ...

Installing a recycle valve in parallel with the antisurge valve of a turbine-driven multistage (low pressure/high pressure) centrifugal compressor, in combination with control system modifications, ...

A new nonlinear predictive approach allows natural gas pipeline reciprocating compressors to respond rapidly to changing processes by omitting undesired or dangerous operating steps, preventing costly ...
