Factors Affecting the Economic Benefits of Hydrogen Production from Methanol

Installation scale

As the scale of the installation increases, the investment per unit of hydrogen production capacity will be significantly reduced, thereby reducing investment and depreciation costs, and labor, power, and maintenance costs will be significantly reduced. After the scale of the device increases, a small amount of investment may be increased, and the optimization of the PSA-H2 process can increase the hydrogen recovery rate and reduce the unit hydrogen raw material consumption.

Comprehensive utilization capacity

Equipped with PSA-CO2 recovery device, the desorption gas can be used to greatly reduce the cost of hydrogen. Pressure swing adsorption desorption gas mainly contains H2, CO2, and a small amount of CO and methane. It can generally be recycled as a low-calorific value fuel and used as a heat carrier heating fuel, which can reduce overall energy consumption and improve overall economic benefits.

Raw material methanol price

It accounts for 70% to 90% of the cost of hydrogen. Lowering the purchase price in the purchase of raw materials and reducing transportation and storage costs and losses are the main means to reduce the cost of hydrogen.

PSA hydrogen recovery rate

PSA-H2 process optimization, efficient use of adsorbents to improve hydrogen recovery can be made effectively reduce cost and improve economic benefits of hydrogen.
