Nigeria's First LNG Regasification Station

Project Overview
The successful commissioning of Nigeria's first LNG regasification station marks a groundbreaking achievement for the country in the efficient utilization of liquefied natural gas and the development of clean energy infrastructure. As a national-level strategic energy project, the station employs an efficient ambient air vaporization process to stably convert imported LNG into high-quality pipeline natural gas, providing a reliable gas source for local industrial users, gas-fired power plants, and the urban gas distribution network. The project not only effectively alleviates domestic natural gas supply constraints in Nigeria but also, with its advanced technology and high-reliability design, sets a technical benchmark for the large-scale, standardized development of LNG regasification infrastructure in West Africa. This fully demonstrates the contractor's comprehensive capabilities in the international high-end energy equipment sector.

Core Product & Technical Features

1. High-Efficiency Large-Scale Ambient Air Vaporization System
   The station's core employs a multi-unit parallel array of large-scale ambient air vaporizers, with a single-unit vaporization capacity exceeding 10,000 Nm³/h. The vaporizers feature an efficient finned-tube and multi-channel air flow path design, achieving zero-energy-consumption vaporization through natural convection heat exchange with ambient air. The process requires no additional fuel or water resources, making it highly suitable for Nigeria's consistently warm climate and delivering exceptional energy efficiency and economic performance.
2. Reinforced Design for Tropical Coastal Environment
   To withstand Nigeria's harsh coastal industrial environment characterized by high temperature, high humidity, and high salt spray, the entire system underwent comprehensive weather-resistance reinforcement:
   • Materials & Coatings: Vaporizer cores and process piping utilize corrosion-resistant special aluminum alloys and heavy-duty anti-corrosion nano-coatings.
   • Structural Protection: Optimized fin spacing and surface treatment prevent performance degradation from condensation and salt spray accumulation in high-humidity conditions.
   • Electrical Protection: Control systems and electrical cabinets achieve an IP66 protection rating and are equipped with moisture-proof and heat dissipation devices.
3. Multiple Safety Interlocks & Intelligent Control System
   The system establishes a multi-layered protection architecture covering process control, safety instrumentation, and emergency response:
   • Intelligent Vaporization Control: Automatically adjusts the number of operating vaporizer units and their load distribution based on ambient temperature and downstream demand.
   • Active Safety Monitoring: Integrates laser gas leak detection and real-time diagnostics and for critical equipment status.
   • Emergency Shutdown System: Features an independent Safety Instrumented System (SIS) compliant with SIL2 standards, enabling rapid and orderly shutdown in the event of station-wide faults.
4. Stable Operation Assurance for Unstable Grid Conditions
   To address the challenge of frequent local grid fluctuations, critical system equipment incorporates wide-voltage input design. The control core is supported by Uninterruptible Power Supplies (UPS), ensuring continued operation of the control system during voltage fluctuations or brief power outages. This maintains station safety or facilitates an orderly shutdown, safeguarding system security and equipment lifespan under extreme conditions.

Project Value & Industry Significance
As Nigeria's first LNG regasification station, this project not only successfully established the complete energy chain of "LNG import - regasification - pipeline transmission" for the country but also, by validating the high reliability and economic viability of large-scale ambient air vaporization technology in a tropical coastal industrial environment, provides a tested systematic solution of "core process package + key equipment" for Nigeria and the wider West African region to develop similar infrastructure. This project highlights the company's capabilities in extreme environment design, integration of large-scale clean energy equipment, and delivery to international high standards. It holds profound strategic significance for promoting regional energy structure transformation and ensuring energy security.
