Comparison of hydrogen production by methanol cracking and ammonia cracking
With the deterioration of the natural environment, the current environmental protection law has gradually become very strict, and the demand for hydrogen as an environmentally friendly new energy source is also increasing. There are also many kinds of hydrogen production technologies that have been developed rapidly. Taking methanol cracking hydrogen production and ammonia cracking hydrogen production as a comparison, what are their respective characteristics and how to choose The following methanol cracking hydrogen production catalyst manufacturer-Suzhou Jiarui gas comes to talk to you. Suitable scale : methanol cracking hydrogen production is suitable for 1500Nm3 / h or less, ammonia cracking hydrogen production is suitable for 800Nm3 / h or less.
Application : Methanol cracking hydrogen production is generally in medium-sized high purity hydrogen production occasions, ammonia cracking hydrogen production is in small hydrogen production occasions, there is no special requirement for nitrogen, but liquid ammonia hydrogen production contains N2, it is difficult to separate, and the power cost is too high.
Safety : Liquid ammonia in ammonia cracking hydrogen production must be liquefied and stored under pressure, which is more dangerous, while methanol in methanol cracking hydrogen production can be stored at room temperature and pressure, which is relatively safer.
2.Investment cost : Ammonia cracking hydrogen production has relatively high equipment requirements, special equipment material requirements, and large initial investment. The cost of hydrogen is about 2-2.5 yuan / Nm3. The investment of methanol cracking hydrogen production is less. The investment of 200Nm3 / h methanol hydrogen production unit is about 1.5 million, and the cost of hydrogen is about 1.8-2.5 yuan / Nm3.
To sum up, compared with ammonia cracking hydrogen production, methanol cracking hydrogen production is more convenient and safer in raw material storage and more cost-effective in investment. The above is the comparison of methanol cracking hydrogen production and ammonia cracking hydrogen production explained by Suzhou Jiarui gas, a catalyst manufacturer for methanol cracking hydrogen production, hoping to help everyone.
