Understanding Enalysis Reports and Alerts

An Enalysis report provides a snapshot of compressor performance and health for a specific operating point. It combines measured operating data with calculated process variables so users can review how the compressor is operating and identify conditions that may need attention.

Reports can include warning and severe flags on both measured and calculated values. Reviewing the current report together with previous reports and trends can provide additional context when evaluating a compressor condition.

What information is included in an Enalysis report?

The information available depends on the compressor type and the data available for the asset. Enalysis reports can include measured operating information as well as calculated performance and health indicators.

• Measured operating data: Information such as pressures, temperatures, compressor speed, flow, and other available field data.
• Calculated performance information: Values such as power for compression used, total power used, driver power utilization, compressor capacity utilization, and incremental production possible.
• Reciprocating compressor calculations: Examples include Blowby efficiency, expected discharge temperature, compression ratio, volumetric efficiency, rod loads, cylinder power, cylinder flow, and degrees of reversal.
• Rotary screw compressor calculations: Examples include compression ratio, optimum Vi setting, slide valve adjusted capacity, volumetric efficiency, over or under compression, compressor flow, and oil flow.

What do the report colors mean?

Enalysis uses flags to help draw attention to operating or calculated values that have crossed configured thresholds.

• Yellow indicates a warning condition.
• Red indicates a severe condition.

The value or condition that triggers a warning or severe flag depends on the metric, compressor type, and applicable asset setup. A flag should be reviewed together with the surrounding operating information rather than as an isolated value.

What types of conditions can be flagged?

Flags can be applied to measured inputs and calculated process variables. Depending on the compressor type, examples may include temperature, pressure, Blowby, rod load, volumetric efficiency, over compression, under compression, oil related conditions, and other performance or equipment health indicators.

The exact flags available will vary by compressor type and configuration.

How should I review a flagged Enalysis report?

Use the report as a starting point for understanding what changed and whether additional investigation may be needed.

1. Confirm that you are reviewing the correct compressor and report date.
2. Identify any yellow warning or red severe flags.
3. Review the measured and calculated values associated with the flagged condition.
4. Compare the value with previous reports or trends when historical information is available.
5. Consider whether operating conditions, configuration, or recent maintenance could help explain the change.
6. If the condition is unclear or requires additional review, contact your Detechtion Engineering Account Manager or Enalysis Support.

Why are trends important?

A single Enalysis report represents compressor health and performance at a specific point in time. Looking at how measured and calculated variables change over multiple reports can provide additional information for configuration decisions, optimization, and maintenance planning.

For example, a calculated value that is stable over time may provide different context than a value that is increasing or changing rapidly. Reviewing trends can help users determine which changes deserve closer investigation.

Are report flags the same as email notifications?

No. A flag is part of the Enalysis report and identifies a warning or severe condition. Email notifications determine whether and when a user receives an email when qualifying reports are generated.

Email preferences can be configured to receive reports based on warning level, Cash Flow Risk criteria, reporting frequency, and assigned areas or fields. These settings are covered in a separate knowledge article.
