Process for desublimation in a fluidised bed

摘要

For desublimation of desublimatible constituents from a gas mixture in a fluidised bed of solid particles of the substances to be desublimated, the temperature of which is kept below the triple point temperature of the substances to be desublimated, with indirect removal of heat from the fluidised bed by means of heat exchangers arranged in the fluidised bed, the gas mixture is introduced into the fluidised bed above the heat exchangers.
