Turning Industrial Waste into AI Power:
A Coal Chemical Tail Gas Case Study

A technical rendering of a modern coal chemical refinery plant integrated with a high-efficiency ENN EGT20 gas turbine unit and a clean waste-heat boiler stack, showing how low-calorific coal chemical tail gas can be piped directly from industrial chemical processes into the micro gas turbine combustion chamber to convert waste gas into reliable onsite power for AI infrastructure applications.

Coal Chemical Tail Gas: Turning Industrial Waste into AI Power

Xinneng Energy Deployment

Project successfully delivered in June 2023 for Xinneng Energy Co., Ltd. in Ordos, Inner Mongolia

Energy-Saving Renovation

Designed to capture chemical tail gas and convert it into co-generated steam and continuous onsite power through an integrated energy recovery system

Flared Waste & Cabon Burden

Low-calorific-value coal chemical tail gas was being flared continuously, creating wasted energy and heavy carbon emissions

Strict Emission & Cost Barriers

The refinery faced extremely strict regional limits on NOx emissions, combined with rising electricity costs and increasing utility steam procurement costs.

Fuel-Adaptable Combusion

Advanced gas turbine technology capable of stably burning low-BTU, hydrogen-rich chemical tail gas that conventional internal combustion engines cannot handle

Integrated Waste-to-Energy Recovery

The system directs gas turbine exhaust into a waste-heat boiler to produce superheated steam for industrial processes

Power Generation Assets

Primary power is provided by one high-performance ENN EGT20 gas turbine unit

Thermal Recovery Assets

A high-efficiency 12-ton flue gas waste-heat boiler system captures recovered thermal energy for productive reuse

Complete Environmental Compliance

Converted an environmental liability—flared gas—into high-value utility assets while meeting local emissions limits without additional treatment equipment

RELIABLE BEHIND-THE-METER POWER / OPTIMIZED PUE FOR GPU COMPUTING

Proves that complex industrial waste gases can be repurposed as reliable energy assets to support independent, off-grid computing facilities.

CCHP technology directs turbine waste heat to thermal absorption chillers, lowering data center PUE and maximizing the amount of power available for compute workloads.
