The primary process to currently make hydrogen is Steam Methane Reforming (SMR) of natural gas.

![The primary process to currently make hydrogen is Steam
Methane Reforming (SMR) of natural gas. This involves two
reaction steps in the gas phase at high temperature & high
pressure using solid catalysts. The final reactor effluent is
usually separated using a PSA (Pressure Swing Adsorption)
process to produce a very high-purity hydrogen gas stream &
a "tail gas" containing residual methane, CO, & hydrogen
(that can be used for the process's heating requirements).
The table on the right shows the composition of 100 kmol/hr reactor
effluent that must be purified. The separation considerations are:
The reactor effluent is cooled & free water is separated from the
gas. The composition of the remaining water in the dried gas is 0.25
mol%.
