Prediction of selling price of hydrogen produced from methanol steam reforming

ABSTRACT

Hydrogen is a clean energy carrier. However, it is not naturally available and should be supplied from other organic materials such as biomass or other chemicals such as dimethyl ether. In this article, we estimated the selling price of hydrogen produced by methanol steam reforming and evaluated the effect of some influential factors on selling price using Aspen Plus. Validation process showed that the model and experimental results well agree with each other, especially in high temperatures where reaching equilibrium is followed more rapidly. Similar to temperature, pressure can directly affect the economics of methanol synthesis. As pressure increases from 5 atm to 20 atm, selling price decreases.
