SMC has recently delivered multiple sets of marine membrane nitrogen generation units to vessels with dual-fuel (LNG and methanol) systems, marking a solid step forward for the company in the field of green shipping technology.

Marine membrane nitrogen generation systems are an efficient gas separation technology that utilizes the selective permeability of membranes to separate nitrogen and oxygen from the air, thereby obtaining high-purity nitrogen. On vessels, these systems play a crucial role not only in fire suppression but also in cargo protection, fuel systems, engine starting, and ship maintenance, etc.. This is especially important given the global goals for environmental protection and carbon reduction in recent years, which have led to increased attention and promotion of dual-fuel ship propulsion and combustion systems in new and retrofitted ship building projects, with nitrogen generators being an essential component.

The membrane nitrogen generation system delivered by SMC, by minimizing operational costs of vessels and improving their environmental performance, helps to meet the increasingly stringent environmental standards set by the International Maritime Organization (IMO).

The design of the nitrogen systems, certified by classification societies, also considers the complexity of downstream gas system operations. Therefore, the HMI has been optimized to be more concise and intuitive, facilitating easier use and maintenance by crew members. Additionally, the built-in intelligent diagnostic function can monitor the equipment status in real-time, promptly identifying and preventing potential faults, ensuring safe vessel operations while offering the following advantages:

1. High Efficiency and Energy Saving: SMC membrane nitrogen system is well-designed to achieve stable production of high-purity nitrogen with lower energy consumption, saving significant energy for vessels.

2. Compact and Lightweight: Easy to install and deploy in limited cabin space.

3. Intelligent Control: The system operates fully automatically. The integrated intelligent control system can monitor and adjust the nitrogen generation process in real-time, ensuring precise control of nitrogen purity and flow.

4. Safety and Reliability: SMC fully considers the complex operating environment of ships, incorporating multiple safety protection measures to ensure stable operation of the equipment and safe use on vessels.

5. Easy Maintenance: Modular design and easily replaceable membrane components, along with minimizing moving parts and heating elements that are prone to wear or pose risks, make it easier for maintenance and expand the equipment's lifespan.
