Abstract

"PROCESSO USANDO MODO DE CONDENSAçãO EM LEITOS FLUIDIZADOS, COM ENRIQUECIMENTO DE FASE LìQUIDA E INJEçãO DE LEITO". A corrente de reciclagem de fluido parcialmente condensado de um reator de poliolefina de leito fluidizado operando em modo condensado é separada em duas porções por um separador de corrente. Num modo preferido, a corrente menor do separador contém uma razão maior de líquido para gás que a corrente maior. Uma porção da corrente bipartida é injetada abaixo do leito fluidizado e a outra, preferivelmente com conteúdo de líquido melhorado, é injetada no leito fluidizado num nível acima do nível de retirada de produto. A regulação de injeção de líquido acima do nível de retirada de produto como uma função de líquido nos tanques de descarga de produto, reduz o líquido no sistema de descarga de produto, resultando em tempos de ciclo de descarga melhorados e conservação de monómero e de outros materiais mais eficiente que poderiam de modo contrário ser perdidos no processo de descarga.
