Project Overview
Located within an industrial zone in Nigeria, this LNG regasification station is a specialized, fixed-base facility built on a standardized design. Its core function is to reliably and economically convert liquefied natural gas into ambient-temperature gaseous fuel via an efficient ambient air vaporization process, for direct injection into downstream industrial or city gas networks. The station's design focuses on the reliability and economy of the core regasification process, providing the region with an advanced, cost-effective clean energy conversion hub.

Core Product & Technical Features

1. High-Capacity Ambient Air Vaporizers
   The heart of the station consists of fixed, modular ambient air vaporizer units. These vaporizers employ an optimized finned-tube array and enhanced air flow path design, leveraging Nigeria's consistently high ambient temperatures to achieve exceptional natural convection heat exchange efficiency. The vaporization capacity can be flexibly configured with single or multiple parallel modules to meet sustained, high-load demand, all without consuming water or fuel.
2. Robust Design for Hot-Humid Environments
   To withstand local high heat, humidity, and salt-spray corrosion, the vaporizer cores and critical piping utilize special aluminum alloys and heavy-duty anti-corrosion coatings, with key structural components treated for resistance to humid aging. The overall layout is optimized via CFD flow simulation to ensure stable, efficient heat transfer performance even under high humidity, preventing frost-related efficiency loss.
3. Intelligent Operation & Adaptive Control System
   The station is equipped with an intelligent PLC-based control system that monitors ambient temperature, vaporizer outlet temperature/pressure, and downstream network demand in real time. An integrated load-prediction algorithm automatically adjusts the number of active vaporizer modules and their load distribution based on ambient conditions and gas consumption. This ensures a stable gas supply while maximizing energy efficiency and equipment lifespan.
4. Integrated Safety & Monitoring Architecture
   The design incorporates multi-layered safety protection, including low-temperature interlocks at vaporizer outlets, automatic overpressure relief, and plant-wide combustible gas leak detection. Critical data is fed to a local control center with secure remote access, enabling transparent operation and proactive risk. The system is designed for resilience against grid fluctuations, with critical instrumentation and control loops backed by Uninterruptible Power Supplies (UPS).

Localized Technical Service Support
The project focused on the supply, commissioning, and technical handover of the core regasification process package and equipment. We provided in-depth operation and maintenance training for the local team specific to this ambient air vaporizer station and established channels for long-term technical support and spare parts supply, ensuring optimal performance throughout the facility's lifecycle. The station's operation provides Nigeria and similar climatic regions with an LNG regasification solution characterized by high dependence on natural cooling, low operating costs, and straightforward maintenance, demonstrating the outstanding adaptability and reliability of core process equipment in challenging environments.
