Abstract

Patente de Invenção: <B>"FORNO DE PIRóLISE COM UMA ESPIRAL RADIANTE EM FORMATO DE "U" COM ALETAS INTERNAS"<D>. A presente invenção refere-se a um aquecedor de combustão para aquecimento de um fluido de um processo que usa tubos U dotados de maior superfície interna para transferência de calor para reduzir as temperaturas do metal do tubo e a coqueificação e ao mesmo tempo não é propenso a ficar entupido com coque. O aquecedor de combustão compreende um recinto de seção radiante com alguns tubos U na seção radiante. Os tubos U são formados por conexão de uma ou mais seções tubulares e os tubos U são dotados de aletas internas geralmente longitudinais. A invenção também é dirigida a um processo que utiliza um aquecedor com aletas com tubos U como divulgado para a produção de olefinas a partir de estoques de alimentação de hidrocarboneto.
