Smr Process Flow Diagram. Introduction to steam methane reforming steam methane reforming smr is a chemical process used in the gas manufacturing industry to produce hydrogen on a large scale. It can be seen in figure 1 that co 2 is present in three streams which are depicted as.
A block flow diagram for a typical hydrogen production plant is shown in figure 1. Also designing of the process plant equipment is very essential for the process flow diagram. The reaction is strongly endothermic δh sr 206.
