Abstract
MéTODO PARA REVESTIMENTO DE COMPOSTOS ORGâNICOS VOLáTEIS POR SISTEMAS DE PULVERIZAçãO EXTERNA PARA PINTURA UTILIZANDO EMULSõES AQUOSAS DE SOLVENTES. Processo para revestimento de quantidades de materiais compostos de carbonil por gasto de derivados de emulsões aquosas de solventes por sistemas de captura e tratamento de pulverização externa para pintura na qual o gasto de emulsão aquosa de solvente é removida do sistema de captura e tratamento de pulverização externa para pintura e alimentação dentro do vaso reacional. O vaso reacional empregado inclui um compartimento externo definindo uma câmara de reação e uma pluralidade de palhetas de mistura móveis posicionadas na câmara de reação. A área superficial das palhetas de mistura são mantidas a uma temperatura suficiente para gerar composto de carbonil volátil. O interior do vaso reacional é mantido à vácuo. O gasto de emulsão aquosa de solvente é processada no vaso reacional por um intervalo suficiente para gerar composto de carbonil volátil. O material composto de carbonil volatilizado gerado é removido do vaso reacional por reciclagem e reutilização e o material sólido residual remanescente no vaso reacional após geração de material composto de carbonil volatilizado é removido. O gasto de emulsão aquosa de solvente que pode ser tratada por processo de revestimento de solvente da presente invenção contém compostos de carbonil selecionados do grupo constituído de ésteres de álcool secundário, derivados de ésteres de álcool secundário, e mistura deles e possui um ponto de ebulição de no mínimo 150°C, uma pressão de vapor entre 6,579 X 10^ -4^ atm (0,5 Torr) a 20°C. O gasto de emulsão aquosa de solvente processada pelo método de revestimento de carbonil pode ainda ser préviamente desidratado para produzir um gasto de material da emulsão aquosa de solvente com uma quantidade menor ou com nenhuma água remanescente ou pode ser processada com mais ou toda a porção de água da presente emulsão. Em cada exemplo, a porção de água pode ser gerada com o composto de carbonil.
