Cost introduction of natural gas hydrogen production plant
The cost of hydrogen production from natural gas mainly includes two aspects : one is variable cost, and the other is non-convertible cost. The comprehensive cost of hydrogen production from natural gas is related to the operating life of the project, the price of natural gas and the annual production capacity. Therefore, related projects should fully understand the price of natural gas and the demand for hydrogen when carrying out hydrogen production projects from natural gas. The following natural gas hydrogen production device manufacturer-Suzhou Jiarui gas to tell you in detail about the cost of natural gas hydrogen production device :
Variable cost
1, the cost of deionized water
This is mainly based on the actual operation to determine the cost of deionized water, taking a factory as an example, this factory produces 1 cubic meters of hydrogen will consume 1.4 Kg deionized water, and then according to the current market price to know every kilogram of deionized water is 0.05 yuan, then the factory produces 1 cubic meters of hydrogen will consume the cost of deionized water is 0.07 yuan.
2. Cooling water cost
The cost of cooling water is also determined according to the actual operation. Taking a factory as an example, this factory consumes 5Kg of cooling water for every 1 cubic meter of hydrogen produced, and then knows according to the current market price. The price of cooling water per kilogram is 0.003 yuan, so the cost of cooling water for each cubic meter of hydrogen produced by the factory is 0.015 yuan.
3, electricity costs
Taking a factory as an example, according to the actual operation situation, this factory will consume 0.34 kW · h of electricity for every 1 cubic meter of hydrogen produced. If the electricity price is taken at 0.6 yuan / kW · h, the cost of electricity consumption for every 1 cubic meter of hydrogen produced by the factory is 0.204 yuan.
4, natural gas costs
Taking a factory as an example, according to the actual operation situation, the factory will consume 0.49 cubic meters of natural gas for every 1 cubic meters of hydrogen produced. The calculation formula of the cost of natural gas consumed by the factory to produce 1 cubic meters of hydrogen is as follows : C1 = 0.49 * P
Where C1 represents the cost of natural gas consumed per unit of hydrogen under standard operating conditions, and P represents the price of natural gas per unit volume.
Finally, the total variable cost formula can be obtained by adding the costs of the above aspects :
C change = 0.07 + 0.015 + 0.204 + 0.49P = 0.289 + 0.49P
Cannot be turned into this
1. Depreciation fee
Taking the above factory as an example, it is assumed that the total investment I of the factory is 50,000,000 yuan, the running time t is 18 years, the discount rate i is 5 %, and the total depreciation fee can be calculated according to the following formula :
C3 = I ( 1 + i ) n / t
Through the above formula, and then substituted into the calculation formula, the annual depreciation fee is 2.92 million yuan.
2, maintenance costs
The maintenance cost per unit of hydrogen production is 0.005 yuan. The annual maintenance cost is calculated according to the following formula : C4 = 0.005 V. V is the amount of hydrogen produced by the plant each year ( cubic meters / year ).
3.Employee wages
Assuming that the project requires 15 people, each person 's annual total salary including bonus is about 100.000 yuan, then the employee 's salary in this year is 1,500,000 yuan.
4.Marketing and management fees
The marketing fee is 0.025 of variable cost, and the management fee is 0.035. Therefore, the calculation formula of the annual management fee and marketing fee is as follows : C5 = 0.06 ( 0.289 + 0.49P ) V. Therefore, can not be turned into this is :
C solid = 4,420,000 + 0.005V + 0.06 ( 0.289 + 0.49P ) V
The total cost is C total, C total = C change + C solid = 0.289 + 0.49P + C solid / V
It can be seen from the above formula that the total cost of hydrogen is related to the annual gas production of the plant and the price of natural gas.
