    摘要： An apparatus for producing nitrate granules includes a first fluidized bed which is supplied with air that has been conditioned to a relative humidity of less than 30% at 40° C. and heated to a temperature of 40° C. to 100° C. One or more spray nozzles are provided for spraying a nitrate melt into the first fluidized bed to form nitrate granules. The apparatus also includes a second fluidized bed which is in direct communication with the first fluidized bed. Nitrate granules formed in the first fluidized bed flow directly to the second fluidized bed where they are cooled to a temperature of less than 60° C. The nitrate granules produced by the apparatus and process of the invention are spherical in shape, hard and dry and do not break down easily during handling. The apparatus according to the invention is compact, capable of very high product rates, and can be operated by one operator.

    摘要： Ammonium nitrate is phase-stabilized by a synergistic phase stabilization additive combination of at least cupric oxide and potassium nitrate. Specifically, phase-stabilized ammonium nitrate contains between about 94.0 and about 96.0 wt. % ammonium nitrate and between about 4 and 6 wt. % of a synergistic phase stabilization additive combination of at least cupric oxide and potassium nitrate, wherein the cupric oxide is present in a relative amount of no more than about 2.0 wt. %. In some cases, additional stability is imparted by the inclusion of zinc oxide such as in a relative amount of no more than about 1.5 wt. %.

    摘要： In a process for producing phase-stabilized ammonium nitrate (AN), a diammine complex of Ni or Cu is incorporated into the AN lattice, in which the diammine complex is produced in a solid-state reaction of AN and metal oxide at 110.degree. to 170.degree. C. and in a proportion of up to 10% is either mixed with further AN and melted, homogenized and subsequently transferred into the solid state, or mixed with further AN is incorporated into the AN lattice at between 80.degree. and 170.degree. C. in a solid-state reaction.

    摘要： The present invention provides a process for preparing low D.E. starch hydrolysates and low D.E. conversion syrup products which are both liquid and solid. Starch is treated with bacterial alpha amylase to a D.E. less than 15. The hydrolytic action of the amylase is terminated by heat treatment and the resulting hydrolysate is further converted with bacterial alpha amylase to a D.E. between about 5 and about 20. From the resulting hydrolysate product is obtained a non-hazing syrup which is substantially completely water soluble.

    摘要： Disclosed are after-treatment processes and apparatus for synthesis plants, particularly urea and ammonium nitrate plants, but applicable also to various other plants in which the synthesis reaction does not go to substantial completion. In such plants product is fed to an evaporator for concentration and then to a solidification stage. The vaporous overhead stream from the evaporator contains entrained synthesis product, one or more unreacted starting materials, and solvent (usually H.sub.2 O). It is condensed, and the condensate is brought into mass and heat exchange relationship with the vaporous overhead stream from the evaporator substantially without material transfer of solvent to the condensate stream. The condensate stream is thereby enriched in synthesis product, heat is added to it, and unreacted starting material is desorbed from it. The product-enriched condensate is delivered to the solidification stage for processing there. Production capacity is increased and plant effluent is decreased or eliminated.
