Abstract: Apparatus, materials, and methods for removing ammonia from fluids using metal hydroxides (e.g. zinc hydroxide) and metal loaded media (e.g. zinc loaded ion exchange resins); the metal hydroxides and metal loaded media may be regenerated with a weak acid (pKa between 3 and 7). Alternatively, ammonia is removed from fluids by using H2SO4 and ZnSO4 and metal loaded media; the metal loaded media may be regenerated with H2SO4 and ZnSO4; the ammonia containing H2SO4 and ZnSO4 may be concentrated as necessary to form (NH4)2SO4.ZnSO4.6H2O (ammonium zinc sulfate hexahydrate) crystals. These crystals are removed from the mother liquor and heated to temperatures exceeding 200 ~C releasing NH3 and H2O vapor upon the decomposition of the crystals.

Abstract: A method is described for the recovery of high yields of monomers from waste and scrape polymeric materials with mini- mal amounts of char and tar. The process involves pyrolysis in a circulating fluid bed (CFB). The polymer is heated to a tempera- ture of about 650 .degree.C to about 1000 .degree.C at a rate of more than 5 00 .degree.C/sec in less than two seconds. Heat is supplied to the CFB by a stream of hot sand heated in a separate combustor. The sand is also used a s the circulating fluid bed material of the CFB. The process is essentially devoid of solid carbon char and non-monomeric liquid products.

Abstract: 2106849 9316329 PCTABS00025 A nested fiber gas burner (10) is formed with a burner body (12) having an inlet (14) on one end and a burner port (16) on the other end. A mat (22) of fibers is formed from discrete fibers of material randomly deposited into a mold having the general configuration of the burner port. After the fibers are deposited in the mold to a depth of about 0.5 inch, they are heated to a temperature of about 1200 ·C for about two hours, which causes the fibers to bond together. Thus bonded, the fiber mat is secured in place in the burner port.

Abstract: Aparato, materiales y procedimientos para eliminar amoniaco de fluidos utilizando hidróxidos metálicos (por ejemplo, hidróxido de zinc) y medios de carga metálica (por ejemplo, resinas intercambiadoras de iones cargadas de zinc); los hidróxidos metálicos y los medios de carga metálica pueden regenerarse con un ácido débil (pK{sub,a} entre 3 y 7). Alternativamente, se elimina el amoniaco de fluidos utilizando H{sub,2}SO{sub,4} y ZnSO{sub,4} y medios de carga metálica; los medios de carga metálica pueden regenerarse con H{sub,2}SO{sub,4} y ZnSO{sub,4}; el amoniaco que contiene H{sub,2}SO{sub,4} y ZnSO{sub,4} puede concentrarse si fuera necesario para formar cristales de (NH{sub,4}){sub,2}SO{sub,4}uZnSO{sub,4}u6H{sub,2}O (sulfato hexahidrato de amoniaco y zinc). Los cristales se eliminan del licor madre y se calientan hasta temperaturas que sobrepasan los 200ºC liberando NH{sub,3} y H{sub,2}O vapor por descomposición de los cristales.

Abstract: A method is described for the recovery of high yields of monomers from waste and scrape polymeric materials with minimal amounts of char and tar. The process involves heating the polymer at a heating rate of at least 500 DEG C./sec in a flow-through reactor. Heating is accomplished by contacting the polymer with a heat transfer material such as hot incandescent sand. A flow-through reactor is used to provide the high heating rates and short reactor residence times for the monomer product. The flow through reactor may be a circulating fluidized bed reactor, an entrainment reactor, a cyclonic reactor or a gravity reactor.
