Latest Patents

Hoogerwerf's latest patent focuses on a control method and apparatus for critical rotational speed avoidance in a compressor-expander set within a gas refrigeration system. This innovative approach involves varying the opening of an antisurge or recycle valve, which allows for the adjustment of shaft power used by the compressor. By doing so, the rotational speed of the compressor-expander set can be modified to steer clear of critical speed zones. Additionally, the patent includes a feature where a feedforward signal from a control system prompts the antisurge valve for a recycle compressor to open during a trip or shutdown of one compressor-expander set.
