Petrotech, Inc.
Petrotech Inc. provides turnkey retrofit gas turbine control and auxiliary systems for industrial and aeroderivative turbine driven generator sets and compressors. This retrofit control system replaces outdated and unreliable pneumatic, electro-hydraulic, analog, and relay based systems. This open hardware system is based on a PLC platform of customer choice including systems from Allen Bradley, General Electric, Siemens, Modicon, and ICS Triplex.
Control functions typically include (depending on equipment) dynamic fuel control, discrete sequencing and protection, loadsharing, synchronization, combustion monitoring, data acquisition, compressor control, station control, and others.
Advantages of this approach include lowest possible cost, reduction in overall system complexity, ability to add or modify control functions as requirements dictate, maximum utilization of capital investment in existing equipment, training and spare parts inventory, and simple integration into plant information systems.
Turbine auxiliary systems include fuel system upgrades and conversions (dual fuel), water injection systems, hydraulic system upgrades, and thermocouple and speed sensing system upgrades.
Petrotech has been providing turbomachinery controls since 1978, and has over 1000 systems installed throughout the world, including 250 open architecture gas turbine control systems which have logged more than 6 million operating hours.
Petrotech has complete turnkey capability to design and execute control system projects, from initial design to system installation, using our employees; no subcontractors are utilized.
