processo de reciclagem de gás de alto-forno e dispositivo associado |
摘要 |
A process for recycling blast furnace gas is provided. At least one portion of the gases resulting from the blast furnace undergo a CO2 purification step to create a CO-rich gas which is reinjected at a first top injection point at a temperature between 700° C. and 1000° C. through a top injection line, and at a second bottom injection point at a temperature between 1000° C. and 1300° C. through a bottom injection line. The gases from the bottom and top injection lines are heated at a temperature between 1000° C. and 1300° C. A portion of the CO-rich gas exiting the purification step is directly introduced into the top injection line via a cold gas injection line to obtain a temperature between 700° C. and 1000° C. at the first top injection point. The gas that flows through the bottom and top injection points controlled upstream of the system of the heaters. A device is also provided. |
