A flexible bag for receiving flowable material is suspended, as from a gantry, and is tethered transversely and yet has substantially free movement along three sides for complete filling. The length of the tethers may be selected to prevent complete collapse of the bag when empty, and tubular perforated members having an "H" configuration within the bag may be provided for this purpose. Auxiliary structures provide for cooling of materials provided to the bag, their diffusion on inlet to the bag, their recirculation in the bag, and their removal from the bag. Accessories for use with wet gas provide for separation of inlet liquid and drainage of condensate within the bag.
