Abstract: A vapor relief strainer cleaning assembly comprises a turbine and dislodger assembly, wherein the turbine is configured to move a dislodger assembly disposed within a vapor screen relief vessel. Exemplary dislodger assemblies are configured to be powered by vapor or gas and to use excess vapor or gas optionally to dislodge non-condensable contaminants from the filter screen or to facilitate contaminant dislodgement from the inner wall of the filter screen.
