# How Much Water Required For Tonne Of Steam

### Steam reforming

Steam reforming or steam methane reforming is a method for producing syngas (hydrogen and carbon monoxide) by reaction of hydrocarbons with water. Commonly natural gas is the feedstock. The main purpose of this technology is hydrogen reaction is represented by this equilibrium: CH 4 + H 2 O ⇌ CO + 3 H 2. The reaction is strongly endothermic (consumes heat, ΔH r = 206 kJ/mol).

· · At average atmospheric pressure, the expansion ratio between water in its liquid form and steam is 1:1700. This means that under ideal conditions, 1 part of liquid water expands to 1700 times the volume as steam when boiled. Generally, the expansion of water into steam depends greatly on temperature and atmospheric pressure.
