High Efficiency Baseload Power:
A Tuha Oilfield Gas Turbine Case Study

The Tuha Oilfield Project converts low-value oilfield vent gas into useful onsite electricity and heat, replacing traditional electric boilers and reducing gas flaring. By creating a reliable behind-the-meter energy supply, the project improves energy efficiency, lowers operating costs, reduces emissions, and supports cleaner, more resilient industrial power for oilfield operations.

Tuha Oilfield Gas Turbine Case Study: High Efficiency Baseload Power

November 2023 Commissioning

Successfully deployed at a combined oil station in Hami, Xinjiang, specifically to capture and utilize wasted vent gas

Reliable on-Site Energy Recovery

The system is designed to clean and recover oilfield gas-flooding exhaust streams, generating consistent power and heat for local operations

High-Fluctuation, Low-Calorific Fuel

Vent gas diluted with CO₂ creates unstable methane concentrations ranging from 20% to 80%, making it difficult for traditional gas engines to combust reliably

Zero-Flaring Mandates and High Energy OPEX

Operators faced strict zero-flaring environmental mandates while also managing high electricity costs for oil station pumping and heating operations

Fuel-Adaptable Microturbine Technology

Advanced combustion technology enables stable, high-efficiency operation using variable low-BTU gas streams, turning difficult industrial fuel sources into reliable onsite power

Behind-the-Meter CHP Engineering

The integrated CHP system captures turbine exhaust heat to produce process hot water, replacing outdated boiler systems while improving efficiency, reliability, and energy utilization

Power Generation Assets

Features one modular, high-performance ENN EGT4 micro gas turbine unit in the 400 kW class

Thermal Recovery and Fuel Processing

Includes one 500 Nm³/h fuel gas compressor and one 1,500 kW high-efficiency flue gas heat exchanger

CO2 Emissions Reductions

Massive Utility Cost Reduction

Returns more than RMB 8 million annually to the bottom line by eliminating grid electricity purchases and heating-fuel procurement

Total Environmental Compliance

Eliminates smoke and carbon emissions from open flaring while meeting strict local NOx limits without additional denitrification equipment

This project shows how fuel-flexible turbine systems can help AI campuses bypass utility grid delays by using local gas sources for independent onsite power. With CCHP integration, recovered exhaust heat can drive lithium-bromide absorption chillers, supporting data center cooling while preserving electrical capacity for compute workloads.
