Abstract
"SISTEMA E PROCESSO PARA PROPORCIONAR A UM REATOR POSSUINDO LEITOS FLUIDIZADOS UMA MISTURA DE UM GáS CONTENDO OXIGêNIO E UMA CORRENTE DE REAGENTE GASOSO PARA PRODUZIR UM ANIDRIDO". Um sistema proporciona a um reator de leito fluidizado um gás contendo oxigênio e uma corrente de reagente gasoso usando um borrifador para inserir o gás contendo oxigênio dentro da corrente de reagente gasoso. Uma linha de alimentação acopla o borrifador no leito fluidizado do reator e introduz a corrente de reagente gasoso e o inserido gás contendo oxigênio diretamente em contacto com o leito fluidizado. Um controlador controla e mantém ambas as quantidades de gás contendo oxigênio e de reagente gasoso acima de um limite superior de inflamabilidade, de preferência com uma margem de segurança de pelo menos 10%.
