Title:
FACILITY FOR PRODUCING DIRECT REDUCED IRON AND PRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/225256
Kind Code:
A1
Abstract:
[Problem] With regard to a facility for producing direct reduced iron and production method, the present invention addresses the problem of solving the problem of impurities admixed from, e.g., iron ore powder, and toxic dissolved gases, and substantially reducing the water consumption without being governed by locational factors. [Solution] In a facility for producing direct reduced iron, gas containing large amounts of steam, e.g., the gas discharged from an externally heated reformer is cooled to recover the water fraction in the gas. In addition, a cooling water system is provided with a degasification facility to remove toxic dissolved gases, and is provided with a desalination function and a solids separation function to remove impurities contained in feed water and impurities admixed from, e.g., the iron ore powder, thereby functioning as a purifier. The requirement for make-up water is then either substantially reduced or is eliminated. Contaminated wastewater is also made unnecessary.
