Core Systems & Technical Features

1. Pure Ambient Air Large-Scale Vaporization System
   The project utilizes a multi-unit parallel array of large-scale ambient air vaporizers as the sole regasification method, with a total design capacity of 100,000 cubic meters per day. The vaporizers feature an optimized design with high-efficiency finned tubes and multi-channel air flow paths, fully leveraging ambient air for natural heat exchange. This achieves zero fuel consumption, zero water usage, and zero direct carbon emissions throughout the entire vaporization process. The system boasts excellent load regulation capability (30%-110%), intelligently adjusting the number of operating units based on gas consumption fluctuations from mining shifts and equipment cycling, enabling precise supply-demand matching and high-efficiency energy utilization.
2. High-Reliability Design for Harsh Mining Environments
   Specifically reinforced to withstand the demanding mining environment of high dust, large temperature variations, and strong vibrations:
   • Clog-Resistant Design: Optimized fin spacing and surface treatment effectively prevent dust accumulation from impairing heat transfer efficiency.
   • Stable Operation Across Wide Temperature Range: Key materials and components are suited for ambient temperatures from -30°C to +45°C, ensuring stable performance under extreme.
   • Vibration-Resistant Structure: Vaporizer modules and support structures are reinforced against vibration to meet the challenges posed by continuous vibrations from heavy mining equipment.
3. Intelligent Operation & Mining Site Dispatch Platform
   An intelligent gas supply management platform with bidirectional "Station Control + Mine Dispatch" linkage is established. The platform not only monitors parameters like ambient temperature, vaporizer outlet temperature/pressure, and pipeline pressure in real-time but also automatically optimizes vaporizer operation strategies based on weather conditions and gas consumption forecasts. It can interface with the mine's Energy Management System (EMS), enabling precise gas demand forecasting based on production schedules and proactive supply dispatch, achieving smart supply-consumption synergy and maximized energy efficiency.
4. High-Level Inherent Safety & Emergency System
   The project strictly adheres to the highest mine safety regulations and hazardous material management standards, incorporating multiple layers of safety:
   • Inherent Safety: The pure ambient air process involves no combustion or high-temperature pressure vessels, offering high inherent system safety. Critical piping and equipment are still SIL2 safety certified, with redundant safety relief and emergency shutdown systems.
   • Active Protection: Equipped with mining-specific combustible gas leak detection, intelligent video analytics, and an alarm linkage system with the mine fire service.
   • Emergency Reserve: Leveraging the "cold" storage advantage of the on-site LNG tanks combined with the vaporization system's rapid start-up capability, the facility can provide stable and reliable emergency gas supply for critical mine loads in the event of an external gas supply interruption.

Project Value & Industry Significance
The successful implementation of this project not only provides the mining customer with a stable, low-carbon, and cost-competitive energy option, effectively reducing its production carbon footprint and environmental pressure but also pioneers the large-scale, systematic application of pure ambient air LNG regasification technology in China's mining sector. It successfully validates the reliability and economy of this technology for large-scale continuous operation in harsh industrial environments.  This project highlights the company's comprehensive strength in delivering large-scale clean energy gas supply solutions centered on innovative, low-carbon technologies for complex industrial scenarios. It holds profound and leading significance for promoting the energy structure transformation of China's mining industry and the broader heavy industrial sector.
