Abstract
Relates to a process and apparatus that improves the hydrogen production efficiency for small scale hydrogen production. According to one aspect, the process provides heat exchangers that are thermally integrated with the reaction steps such that heat generated by exothermic reactions, combustion and water gas shift, are arranged closely to the endothermic reaction, steam reformation, and heat sinks, cool natural gas, water and air, to minimize heat loss and maximize heat recovery. Effectively, this thermally integrated process eliminates excess piping throughout, reducing initial capital cost.
