Elliott Group announced the rollout of their Gemini compressor performance monitoring system, a focused software system designed for continuous monitoring, evaluation and analysis of compressor performance and associated auxiliary support systems.

The software system was jointly developed with Tri-Sen Systems.

“This next generation compressor control, monitoring, and analysis system will lead to improved operational control, better machine diagnostics, more functional review capabilities and should result in optimized compressor operation with increased plant reliability and efficiency,” says Klaus Brun, director, research & development at Elliott.

While there are other vibration data packages and operating data packages available in the market, Gemini 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 smart phone, tablet or computer, said Jim Jacoby, senior vice president at Tri-Sen Systems.

The Gemini application includes a custom Elliott compressor model (a digital twin) for evaluating compressor performance and changes, an advanced vibration analysis evaluation tool and remote controls monitoring “HMI-twin” which provides contextually relevant compressor and auxiliaries data through an internet browser interface.

The system augments a plant’s predictive and proactive maintenance strategy. 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, Elliott said.

Elliott Group designs, manufactures, and services technically advanced centrifugal and axial compressors, steam turbines, power recovery expanders, and cryogenic pumps and expanders used in the petrochemical, refining, oil & gas, and liquefied gas industries, as well as in power applications. Elliott Group is a wholly owned subsidiary of Ebara Corporation of Japan.

Established in 1976, Tri-Sen Systems pioneered the first digital governor. Since then, Tri-Sen has placed thousands of controls in process plants worldwide. Today Tri-Sen is focused exclusively on turbomachinery controls. The company is headquartered in Webster, Texas.
