Industries, Gas Processing / LNG
Credibility
Proven compressor and process control systems delivered to gas processing and LNG operators worldwide, backed by more than a half-century of field-verified performance.
From cryogenic NGL recovery to large-scale LNG liquefaction trains, processing operators trust our control systems on their most critical rotating and process assets. With thousands of installations and millions of collective operating hours on refrigeration and process compressors, our solutions help define industry practice rather than just meet it. Programmed to IEC 61131-3 on commercial platforms, they give customers long-term flexibility and ownership, full access to configuration, calibration, and application logic to operate, maintain, and expand.
Applications
Multi-stage compression control for raw gas treating, including suction scrubber interface, inter-stage cooling management, and surge protection for inlet compressors handling variable wellhead gas compositions and pressures typical of gas gathering and treating operations.
BOG recondenser and compressor control for LNG storage tanks and loading terminals, managing the continuous boil-off generation from LNG storage with automated compressor staging, recondenser pressure management, and emergency vent system interface to minimize LNG losses and maintain safe tank pressures during loading operations.
Process automation for TEG dehydration and molecular sieve gas drying systems, including regeneration cycle sequencing, switching valve automation, and dew point monitoring integration to maintain gas quality specifications for cryogenic processing and pipeline injection.
Control for turboexpander/compressor sets in NGL recovery, providing closed-loop speed control, inlet guide vane positioning, expander-compressor shaft balance management, and cryogenic temperature monitoring, engineered to maximize NGL recovery throughput without increasing fuel consumption or operator workload.
Fast, deterministic surge protection for centrifugal compressors under variable inlet conditions, including startup, shutdown, and upset events.
Capture and recompression of flare gas streams for environmental compliance and fuel value recovery, with variable backpressure control, liquid knockout management, and automatic staging of recovery compressors to match variable flare gas generation rates.
Anti-surge and capacity control for propane, ethylene, and mixed refrigerant (MR) compressors in NGL recovery and LNG liquefaction service, including multi-body compressor coordination, intercooler performance management, and the high-speed surge protection essential for cryogenic refrigerant compressors where surge damage is severe and rapid.
High-pressure pump control, vaporizer management, and send-out pressure regulation for LNG import and regasification terminals, including open-rack vaporizer (ORV), submerged combustion vaporizer (SCV), and ambient air vaporizer (AAV) control system integration with pipeline send-out metering systems.
Seamless data integration with plant DCS, process historian, and pipeline SCADA systems via OPC-UA, MODBUS TCP, and other standard protocols, providing the real-time performance and alarm data that plant operations teams and management information systems require.
Integrated control across the full liquefaction train, refrigeration compressor control, expander/compressor balance, heat exchanger approach temperature management, and liquefaction rate optimization. Our liquefaction train controllers are designed for the complex startup and shutdown sequences of multi-stage refrigeration cycles, with full simulation testing before delivery.
Steam turbine drive control for amine regenerator reboiler turbines, plus compressor train control for acid gas injection and sulfur recovery unit feed compression, supporting gas sweetening operations in sour gas processing facilities.
Start/stop sequencing, speed governing, fuel control, and protective shutdown for compression and power-generation drivers.

A MESSAGE FROM JOHN KAZOUR, CEO
To our customers and partners,
For more than 50 years, our team has helped customers keep critical operations running. We built our reputation as Petrotech by taking responsibility for control systems on important rotating machinery.
As more industries came to us with similar challenges across power generation, compression, and hydro applications, our engineering team kept finding ways to solve them. Eventually, the business outgrew the Petrotech name.
We are entering our next chapter as Innova Technologies. The new name reflects the full scope of our work as a rotating machinery control systems specialist. We engineer controls around the machine, deliver complete projects from design through commissioning, and provide support that stays with the problem until it is solved.
Our name is changing, but the people, engineering experience, and commitment behind the work continue. Our responsibility to active projects and installed systems carries forward under the Innova Technologies name. Your current contacts remain the right place to start, and we will communicate directly if an administrative record requires an update.
We appreciate the trust you have placed in us over the decades, and we look forward to continuing that work as Innova Technologies.
CEO, Innova Technologies
