Gemini Compressor Performance Monitoring System

Developed in conjunction with Tri-Sen Systems, the Gemini Compressor Performance Monitoring System is a focused software solution designed specifically for continuous monitoring, evaluation, and analysis of critical compressor performance and associated auxiliary support systems. It is a package that integrates rotor dynamics analysis, process data, high fidelity compressor thermodynamic analysis, and nearly real-time visibility of key performance indicators into a single package that can be accessed from a smartphone, tablet, or computer.

The system augments a plant’s predictive and proactive maintenance strategy and includes:
 
• Ebara Elliott Energy’s custom-designed compressor performance comparison & evaluation

• Advanced vibration analysis

• Remote Controls Monitoring




Digital Twin
The Gemini compressor performance monitor collects high-resolution compressor data by connecting to the compressor controls’ programmable logic controller (PLC) and the compressor vibration monitoring system. The collected data is stored in an integrated “Edge” database, accessed by the Gemini application software, and presented in contextually relevant, easy-to-understand graphics. The application evaluates the compressor performance by first calculating predicted compressor outputs for current process conditions. It uses the Ebara Elliott Energy compressor performance maps, instrumented and modeled process data, application data, and an Ebara Elliott Energy custom compressor model (specific to the compressor and application). The predicted performance value is then compared and evaluated against the actual compressor performance. Deviations in actual compressor performance vs. predicted compressor performance are represented graphically. If push notification is enabled and a change in deviation exceeds a configurable threshold, an SMS or email notification is sent to the appropriate plant personnel.

Vibration Analysis Interface
Accessing vibration data directly from the vibration monitor interface, the advanced vibration analysis tool provides best-in-class vibration evaluation without requiring a commitment to an Enterprise solution. The Gemini vibration analysis application collects high-resolution compressor data by connecting to the compressor controls’ PLC and the compressor vibration monitoring system. The collected data is stored in an integrated “Edge” database, accessed by the Gemini application software, and presented in contextually relevant, easy-to-understand graphics. 

Remote Controls Monitoring
The remote controls monitoring application provides a remote user with the same compressor controls data in the same format as the data presented by the local human machine interface (HMI). Using a “smart” device that supports a web browser, a remote user can access the Gemini via the internet and monitor a given compressor like a local user without actually connecting to the local HMI. After connecting to the Gemini and accessing the Remote Controls Monitoring, you see the same data the operator sees on their local HMI, in the same context, using the same navigation and “drill-down,” but without the ability to affect the compressor control.Remote controls monitoring
