Gas Turbine Selection for Midstream

Gas turbines are widely used as drivers in midstream compressor stations for natural gas transmission due to their high-power density, ability to operate at varying loads, and suitability for remote, unmanned locations.

HighTec Energy support midstream customer to select Gas Turbine:

Output power requirements for the specific transmission segment and expected flow rates.
Fuel flexibility and ability to handle varying Wobbe Index in pipeline gas.
Reliability, availability, and maintenance intervals tailored to site conditions and operating profiles.
Compatibility with ancillary systems such as lube oil, controls, fire suppression, inlet/exhaust, and fuel treatment, which must be optimized for safety and efficiency.
Preference for multi-shaft or aeroderivative turbines where partial load efficiency and flexible operation are required.
Environmental considerations such as emissions compliance and equipment resilience to temperature/fuel variations should be factored into the selection process.

Compressor Optimization Strategies

Centrifugal compressors are the backbone of midstream gas transport due to their capability to operate continuously, high reliability, and ability to handle large flow rates (50–500 MMSCFD per unit).

Hightec Energy supports its customer for optimal operation based on:

Correct matching of compressor and driver for desired capacity, pressure ratio (typically 1.2–2.0 per stage), and required pressure differentials over transmission distances.
Implementation of variable frequency drives (VFD) for precise speed control and efficiency improvements (5–15% at partial loads).
Aerodynamic design optimization, including advanced impeller profiles, minimized tip clearances, and surface finish improvements using CFD tools, can boost compressor efficiency by 2–5%.
Inlet condition management by controlling temperature and moisture to ensure optimal compressor performance and longevity.
Adoption of predictive control, monitoring, and advanced materials (ceramic matrix composites, nano-coatings) for higher temperatures, longer life, and lower fouling rates
