MiamiOH OARS on 25 Oct 18NineSigma, representing Wärtsilä Moss, seeks innovative technologies that can remove water vapor from a continuous air flow. Technologies based on new principles, even at a research stage, are especially welcomed. Wärtsilä provides environmentally and economically sound integrated solutions for various merchant vessels including LNG carriers. When LNG tanks are emptied they have to be aerated to remove all combustible gases. These tanks are however very cold (-40°C) and any vapor in the air will freeze inside the tank. The current air dehumidification method Wärtsilä Moss installs on LNG carriers is based on chillers that cool the air down to 5°C to remove most of the water vapor, followed by passing the air through a desiccant tower packed with activated alumina. Although this approach is effective it is not easy to scale and the installed capacity is not always used in an optimal way. Thus, the client seeks novel techniques which are being developed to dehumidify air or an inert gas like N2.
