We are designing an ammonia production facility for our design project. We will apply the single-stage steam methane reforming process in Linde Ammonia Concept for the production of hydrogen that we will use in ammonia production. However, we are stuck on the mass balance. We need to have produced 7569kmol/h hydrogen at the PSA unit exit. Our natural gas methane percentage is 94%. We want to assume that only methane reacts and produces hydrogen. How should we establish the mass balance? What should the reformer temperatures and pressures be? What should the S/C be? Can we solve this manually or with Excel without using programs like Aspen?
