Dust formation, however, can hardly be avoided when filling the reservoir or container for the soda lime arranged inside the submarine, when the soda lime is transported via long delivery lines into the interior of the submarine. Finally, because of the long and flexible conveying path, the typically used vacuum conveying systems can not meet constant conveying conditions.
