Abstract: An insulated enclosure includes a plurality of walls, each of the walls comprising structural insulated panels joined to adjoining structural insulated panels by joints. Each of the structural insulated panels includes a frame having a first vertical frame member, a second vertical frame member, a top frame member, a bottom frame member, and siding members disposed on opposing sides of the frame to define a cavity therebetween. The vertical frame members define, on an outwardly disposed surface thereof, a plurality of vertical recesses and projections. The joints between the plurality of structural insulated panels are butyl-free and include butyl-free compressible seals disposed between opposing recesses and projections in adjoining structural insulated panels. Insulation is disposed within the structural insulated panels and within at least a portion of at least one structural insulated panel vertical frame member.

Abstract: A structural insulated panel system includes a frame having a first and second vertical frame members and top and bottom frame members. First and second siding members are attached to opposite sides of the frame, the frame and the first and second siding members forming a cavity, with an insulation material within the cavity. The first vertical frame member includes recesses having a first depth and the second vertical frame member includes projections having a second depth. A first compressible seal is disposed within the recesses and is compressed by the projections of an adjacent panel upon assembly. A second compressible seal is disposed adjacent to each outside edge of the first or second vertical frame member and is compressed by the other frame member upon assembly. A plurality of voids are formed in at least one of the frame members and filled with the insulation fill material.

Abstract: A process for granulating ammonium phosphate containing composition for use as a fertilizer which comprises feeding a slurry or melt of ammonium phosphate, wherein said slurry or melt is capable of further reaction with ammonia, into a kneading mill, feeding recycled particles from the subsequent classification and crushing procedure into said kneading mill, wherein the said slurry or melt added to the mill is from 5 to 95% wt.

Abstract: A method for neutralizing nitric acid with ammonia comprising feeding nitric acid into a first aqueous reaction zone, feeding ammonia into a second aqueous reaction zone which has an inlet at the lower portion of the first reaction zone and is in circulating communication therewith, circulating the nitric acid downward within the first reaction zone into the inlet of the second reaction zone so that it is substantially diluted before entering the second reaction zone, whereby a predominent proportion of the nitric acid is reacted with the ammonia in the second reaction zone so as to form an ammonium nitrate solution, and removing the ammonium nitrate containing solution from the second reaction zone and recirculating the ammonium nitrate containing solution from the second reaction zone to the first reaction zone so that the solution and gases therefrom are substantially completely introduced into the first reaction zone with sufficient force so as to create a scrubbing turbulence of the gas as gas bubbles in

Abstract: A thermal syphon-pressure pump neutralizer for neutralizing nitric acid with ammonia, comprising a reaction vessel for containing an aqueous reaction medium and having a gas outlet in its upper end and a product outlet spaced therebelow, a fluid impervious vertically disposed cylindrical member in the vessel defining a second reaction zone therewithin and a first reaction zone between the member and the vessel, the lower inlet end of the cylindrical member being spaced above the bottom of the vessel, ammonia inlet means leading into the bottom of the vessel in close proximity to but spaced below the cylindrical member inlet, nitric acid inlet means leading into the first reaction zone being spaced a predetermined distance above the cylindrical member inlet and below the product outlet, a free gas zone being provided between the reaction zones and the gas outlet and deflector means above the second reaction zone and in communication with the first reaction zone so that solution and gases evolved from the outle
