Traditional steel industries are known as an energy intensive process and a huge stationary source of greenhouse gases. Recently, the residue gases from the steel industry, such as coke-oven gas and blast-furnace gas receive many attentions as a good alternative source to produce energy and high-value chemicals (e.g. methanol and synthetic fuels), they contain various useful raw chemicals including H2, CH4 and CO etc. Especially, the H2 and CO, called synthesis gas is one of important intermediate chemicals which can be widely used in a petrochemical industry. While most of residue gases from the steel industry is currently used as a fuel, many potentials pertain in utilizing them as a raw material by integrating gas separation and synthesis processes. We develop a new process model for the production of energy and high-value from residue gases in the steel industry. Using the developed process model, we performed techno economic evaluation using various criteria (e.g. energy efficiency, economics). |
