PROGNOST®-NT for hyper compressors in LDPE service

Learn how the PROGNOST® technology enables operators to deploy successfully a predictive maintenance strategy and operate safe and reliable compressors.

p-V analyses

p-V diagrams are one of the most important parameters to determine the condition of a compression asset. Hyper compressors usually cannot or must not be drilled for indicated pressure measurements. PROGNOST Systems developed a unique workaround to produce precise p-V diagrams utilizing strain gauges.

This enables operators of LDPE production lines to monitor gas dynamics e.g. to analyze valve action with different gas compositions, check pulsation levels etc.

PROGNOST®-NT Plunger position monitoring

Erratic plunger run out can be monitored with a PROGNOST®-NT orbit visualization of the horizontal and vertical plunger run out and allows to set a threshold to a maximum deflection based on orbit or horizontal and vertical direction.

Operating condition based monitoring

PROGNOST®-NT has the unique capability to detect changing operating conditions automatically. This ensures tight and precisely set thresholds for all condition monitoring tasks. After running the compressor in all necessary operating conditions, the automatic detection of these conditions and the parallel setting of thresholds can be activated. The number of different operating conditions is unlimited. This outstanding feature is available for all compressor types.
