1. Use ammonia decomposition hydrogen production equipment and other hydrogen methods

       cost calculation:

1. The running cost of bottled hydrogen:

The price of ordinary hydrogen in the general market is 18 yuan per bottle, and the standard volume of a 15Mpa bottle of hydrogen is 6M3. In fact, each bottle is only about 4.5M3, so the calculated price of ordinary hydrogen is about 4 yuan per cubic meter. .

The price of pure hydrogen on the market is 68 yuan/bottle. According to the calculation of each bottle, the price of pure hydrogen per cubic meter is about 15 yuan.

2. The operating cost of water electrolysis of hydrogen

Theoretically, electrolysis requires 1 cubic meter of hydrogen to obtain 0.805 KG of pure water, which consumes 2.95 KWH, but actually requires 1 kg of pure water and consumes 4.5 to 6 KWH. This method consumes a lot of electricity and the purity of the hydrogen obtained is high. Typically, the hydrogen content is 99.5 to 99.8%. For example, the operating cost of 1kg of pure water is 1 yuan, and the price of 1KWH is 0.8 yuan. The price of hydrogen per cubic meter is 4.5 to 6 yuan.

3. The operating cost of ammonia decomposition hydrogen:

Each kilogram of liquid ammonia can produce 2.78 standard cubic meters of mixed gas. The market price of liquid ammonia is 2,000 yuan per ton. The liquid ammonia required for each cubic meter of gas in ammonia decomposition hydrogen production equipment is 0.72 yuan. The rated power of ammonia decomposition is generally 1KWH per cubic meter, but in reality, the power consumption per cubic meter of gas is about 40% of the rated power. For example, the price of 1KWH is 0.8 yuan, and the electricity cost per cubic meter of ammonia decomposition gas is 0.8 × 40% = 0.32, calculated as per cubic meter of mixing. The gas operating cost is 1.04 yuan.

       E.g:

According to your company, the ammonia decomposition hydrogen production equipment, the hydrogen consumption per hour is 25 M3/H, and the hydrogen consumption in 24 hours is 600 M3.

1. If ordinary hydrogen is used, the price of ordinary bottled hydrogen is 4 yuan / M3. As shown in the above figure, the total price of hydrogen in one day is 600 × 4 = 2400 yuan.

2. If hydrogen is decomposed by ammonia, the price of hydrogen is 1.04 yuan, and the total price of hydrogen per day is 600 × 1.04 = 624 yuan.

In contrast, if hydrogen is decomposed by ammonia, it can save one day, the cost is 2400-624 = 1776 yuan, and one year can save 1776 × 365 days = 648240 yuan, 25 M3 / H

      The price of ammonia decomposition hydrogen production equipment gas furnace purification device is 65,000 yuan, and the investment in liquid ammonia storage tank equipment is about 10,000 yuan, with a total investment of 75,000 yuan, and the investment can be recovered within one and a half months.
