ARM0F10TELF SAVES ENEM FOR PHOSPHORIC ACID PRODUCERS, COTS COSTS FOR FERTIUIER MAHOFACTORERS.
Dr. Dieter Frank Director of Research Research at Armak's central research laboratory should be viewed as a body of knowledge obtained not only from decades of investigations at McCook, Illinois, but also gathered from other Armak research facilities at Philadelphia and in Canada (Sas katoon). Since Armak is part of a national (Akzona) and interna tional (AKZO) group of operating companies, Armak R & D views itself as one of the transmission points for fundamental knowl edge, new technology and appli cation know-how derived from this worldwide chemical group whose investigations include a wide range of surfactants. The establishment of a technol ogy exchange agreement be tween Armak and AKZO Chemie not only gives both parties access to technology and know-how, but also enables both to draw on resources which are greater than those of their individual R 8c D organizations. One way Armak has fostered this international research effort is by way of an R 8c D personnel exchange. In this method of per sonnel technology transfer, one chemist from McCook and one chemist from Arnhem, The Nether lands, changed places while each applied his knowledge of amines to new fields of applica tion such as metal extraction and antistats for plastics.
With Armoflote LB a new flotation agent for clarifying black ammo nium phosphate fertilizer solutions, phosphate rock no longer requires calcining in order to produce agri cultural grade phosphoric acid. In a novel process developed jointly by the Tennessee Valley Authority (TVA) and Armak Com pany, suspended carbonaceous material is floated to the top of the ammonium phosphate solution and may be removed by skimming or overflow. 80-90% of the original ammonium phosphate solution can be recovered as a clear green liquid while the floated ma terial can be used in the produc tion of other types of fertilizers. The mixing system is shown in the accompanying diagram. Adoption of this system offers im-
Over the years, Armak has pub lished a number of Technical Data Bulletins covering subjects of inter est to both the fertilizer manufac turer and to the mineral producer. Dust Control with ArmofloR Formu lations is described in Bulletin

pressive savings. The extremely energy intensive step of calcining is eliminated resulting in savings of up to 3 million BTU per ton of re covered P2O5. Significant savings are also offered the liquid fertilizer producers since black wet phos phoric acid is cheaper than clear green acid. For further information on this process write for Bulletin 78-10. The process is covered by U.S. Patent 3,969,483 and is available to any one without payment of license or royalty fee. 75-22: Anticaking and Antidusting Agents for Ammonium Nitrate is discussed in Bulletin 78-2; while Armoflo 66 for Anticaking Multicomponent Fertilizers is presented in Bulletin 72-20. Specifications and properties of ArmacR Amine Acetate Salts are fully described in Bulletin 76-30, Copies of these publications may be obtained by writing to: Armak Company, Dept. A, Box 1805, Chicago, IL 60690.
