Abstract
método de operação de um alto-forno, usina de alto-forno e instalação de alto-forno. trata-se de um método de operação de um alto-forno, o dito método compreendendo as etapas de coletar uma corrente de gás de alto-forno a partir do alto-forno; alimentar a dita corrente de gás de alto-forno e um gás contendo hidrocarbonetos a uma usina de reforma composta por pelo menos um reformador; reformar a dita corrente de gás de alto-forno e o dito gás contendo hidrocarboneto na usina de reforma para se produzir uma corrente de gás de síntese; e alimentar pelo menos uma porção da dita corrente de gás de síntese no alto-forno; em que uma corrente de h2 é adicionada ao gás contendo hidrocarbonetos antes da etapa (c) e/ou à corrente de gás de alto-forno antes da etapa (c) e/ou à corrente de gás de síntese antes da etapa (d) e/ou ao tuyere do alto-forno, em que a alimentação de pelo menos uma parte da dita corrente de gás de síntese no alto-forno ocorre através do tirante do alto-forno e/ou através do tuyere do alto-forno, e em que a eficiência de utilização do hidrogênio em uma usina de alto-forno compreendendo o alto-forno, a usina de reforma e uma usina cowper está acima de 60 %.method of operating a blast furnace, blast furnace plant, and blast furnace installation. is a method of operating a blast furnace, said method comprising the steps of collecting a stream of blast furnace gas from the blast furnace; feeding said stream of blast furnace gas and a gas containing hydrocarbons to a reforming plant comprising at least one reformer; reforming said blast furnace gas stream and said hydrocarbon-containing gas in the reforming plant to produce a synthesis gas stream; and feeding at least a portion of said synthesis gas stream into the blast furnace; wherein an h2 stream is added to the hydrocarbon-containing gas before step (c) and/or to the blast furnace gas stream before step (c) and/or to the synthesis gas stream before step (d) and/or to the blast furnace tuyere, wherein the supply of at least a part of said synthesis gas stream into the blast furnace occurs through the blast furnace riser and/or through the blast furnace tuyere, and wherein the hydrogen utilization efficiency in a blast furnace plant comprising the blast furnace, the reforming plant and a cowper plant is above 60%.
