Abstract
An insulated vessel for storing cryogenic liquids and other cold fluids features an inner tank and an outer jacket with spherical aerogel particles positioned in the insulation space formed there between. The insulation material is installed by fluidizing the spherical aerogel particles with dry gaseous nitrogen and subjecting them to a slight positive pressure. A vacuum is simultaneously pulled on the insulation space of the vessel through a filter by a vacuum pump so that the spherical aerogel particles are transferred into the insulation space. The insulation space is then evacuated by the vacuum pump.
