Title: Processo para obtenção de concentrados de titânio com elevado teor de tio2 e baixo teor de radionuclìdeos a partir de concentrados mecânicos de anatásio
Inventor: HORTA RONALDO DE MOREIRA
IPC: C22B1/00
Filed: 2003-10-28
Abstract: "PROCESSO PARA OBTENçãO DE CONCENTRADOS DE TITâNIO COM ELEVADO TEOR DE TIO~ 2~ E BAIXO TEOR DE RADIONUCLìDEOS A PARTIR DE CONCENTRADOS MECâNICOS DE ANATáSIO". A presente invenção trata de um processo original para a produção de concentrado de titânio com baixo teor de radionuclídeos a partir de concentrados mecânicos de anatásio. Este concentrado, com alto teor de TiO~ 2~, destina-se basicamente ao processo cloreto de produção de pigmentos de dióxido de titânio. O processo baseia-se no processamento de concentrados mecânicos de anatásio por meio da seguinte sequência de operações unitárias: calcinação ao ar e redução com hidrogênio ou outro gás redutor, ambas em reator de leito fluidizado ou forno rotativo, separação magnética de baixa intensidade do produto reduzido, separação magnética de alta intensidade da fração não magnética proveniente da separação de baixa intensidade, lixiviação com ácido clorídrico do produto magnético de alta intensidade, filtragem e secagem do produto desta lixiviação, oxidação a alta temperatura do produto da secagem em presença de uma mistura de fluoreto de sódio (NaF) e sílica amorfa (SiO~ 2~), choque térmico do minério oxidado, lixiviação clorídrica do produto da oxidação em presença de fluoreto de sódio, secagem do produto da 2^ a^ lixiviação e separação magnética de alta intensidade, obtendo-se como produto final a fração não magnética desta separação. O processo caracteriza-se por apresentar modificações na seq³ência das operações unitárias conhecidas do estado da técnica, melhoria em praticamente todas as operações unitárias envolvidas e utilização inédita de mecanismos para a remoção de radionuclídeos.

Abstract: A damper has a cylinder and a piston, the piston having two or more parts. A first piston part is made of a rubber-elastic material forced against the cylinder wall during a damping stroke. A second piston part is made of a material that is stiffer in comparison to the rubber-elastic material. The second piston part as seen in the radial direction lies between an area of the first piston part and the cylinder wall. The first piston part may have at least two sections of different hardnesses over its lengths. The piston could also include a piston part that is radially forced outwards to rub against the cylinder wall during damping, the piston part being made as a solid body of a material with rubber-elastic properties which becomes flattened under pressure, deforming in such a way that a friction seal is created between the piston part and the cylinder wall.

Abstract: The invention relates to a galvanosorptive reaction cell with closed substance circulation for the conversion of low temperature heat, preferably of waste heat into useful electrical work. The reaction cell and the accompanying isobaric substance circuit are presented. The galvanosorptive reaction process inside the cell is carried out polytropically with an electrostatic auxiliary voltage, which is superimposed onto the inherent voltage of the cell. In this way, not only free but, with cooling of the reaction system, also substance-bound reaction work can be extracted from the reaction system. The electrical energy yield and the power density of galvanosorptive reaction cell are thereby increased many times over.
