Abstract: A flexible intermediate bulk container has a liner which is provided with one or more hollow suspension members for fastening the liner to an outer container in correct relative position. The suspension means members form vents for expulsion of air from the liner during and subsequent to filling with particulate bulk material. The suspension members are preferably tubular to provide vents for the interior of the liner. Such vents may be controlled by one-way valve devices.

Abstract: A process which comprises reacting ammonia with phosphoric acid in a reaction vessel to form a reaction mixture comprising ammonium phosphate characterized in that the reaction mixture is allowed to foam whereby there is formed a foaming reaction mixture comprising steam and ammonium phosphate; and in that steam and ammonium phosphate are discharged from the reaction vessel through a common outlet. Preferably the ammoniation is carried out under pressure and the foam reaction mixture is discharged via a spray nozzle into a zone of lower pressure where water is evolved spontaneously, e.g. by flash evaporation as the product is sprayed, to give a solid particulate product.
