Abstract
"processo e aparelho para reduzir obstrução da válvula de extração em um processo de polimerização". um processo de polimerização de pasta remove uma porção da pasta fluida sem utilizar um ramal de sedimentação ou uma extração contínua. o processo utiliza uma válvula de extração de reator que está periodicamente fechada totalmente e aberta totalmente de modo que a pasta extraída seja removida do reator em um modo descontínuo. o fechamento total e a abertura total regulares e periódicos da válvula de extração reduzem os casos de obstrução da válvula de extração por polímero. em outro aspecto da invenção, a válvula de extração é estrangulada em um padrão repetitivo para reduzir obstrução da válvula de extração.
