Alfa Laval inert gas solutions for LNG carriers Safeguarding LNG transport Time is money when it comes to transporting liquid natural gas (LNG). Being able to inert the tanks on the voyage to and from dry dock – or to do it on the spot when tank inspections or repair needs arise – is a valuable proposition. Alfa Laval understands the importance of availability, which is why we put so much effort into securing it. When it comes to inert gas systems, availability is a key focus of our system design. The Alfa Laval Smit LNG system is specifically developed to ensure safety without costly and unnecessary delays, which means you can handle tighter delivery schedules and increasing demand. By offering more capacity for the footprint, the Smit LNG system lets you do the inerting faster and get to the work you profit from. Completely soot-free Due to the relatively low investment cost, most larger LNG carriers purchase combustion-based inert gas systems. The gas needs to be not only dry, however, but also free from soot. This is why the unique Ultramizing® combustion system is at the heart of every Smit LNG system. The Ultramizing system Conventional, strongly radiating, long oil flame producing soot. ensures inert gas with low oxygen levels, low NOx emissions and no soot, thanks to special steam-atomizing and vaporizing burners. Quality throughout Quality is also assured by the Smit LNG sprayer systems, which are designed to avoid the creation of salt from evaporating water. The dryers are laid out in such a way that the produced inert gas has a stable temperature and a dew point that is always below what is requested. Modular and smaller The Smit LNG system brings your LNG carrier all the benefits of modular configuration – including a considerably reduced footprint. You pay only for the components you need, achieving a smaller system at a lower cost. The horizontal installation makes it easy to perform inspection and maintenance.
