Simulation of Methanol and Urea Production from Catalytic Conversion of Steel Mill Gases

The time-dependent operation of methanol, ammonia, and urea production units embedded in a steel mill environment is analyzed with dynamic simulation models. From different process concepts and gas availability scenarios, a set of simulation cases is defined with blast furnace gas as carbon and coke oven gas as hydrogen source. Dynamic simulations indicate that significant CO₂ reductions require large amounts of additional H₂ from sustainable sources. From the results, global data such as carbon footprint or energy demands and details about process unit operation are obtained and processed.
