How can this energy be utilized?
Thread Content
Our company has about 50,000 cubic meters of gas containing 9% CO, 10% hydrogen, and the remainder being inert gases. How can this gas be utilized? Can it be used to power boilers?
The combustible component in blast furnace gas is CO, which accounts for about 25%; the contents of H2 and CH4 are very low. CO2 and N2 make up 15% and 55% respectively. This gas can still be used as a fuel. The gas you mentioned can indeed be used as fuel, but before using it, explosion limit tests and combustion rate tests must be conducted to determine the appropriate pressure and pipe diameter for transportation. Additionally, since the gas contains CO, special attention must be paid to the sealing of the transportation equipment.
I agree with what the expert above said. It should be possible to make use of this resource as follows: 1. It’s not clear what the initial pressure and normal instantaneous flow rate of the gas source mentioned by the poster are; if the pressure is high, PSA or other methods can be used to concentrate the gas before utilizing it. 2. It can potentially be used as a supplementary fuel for boilers. 3. Among the options with low investment costs and high efficiency, heating air furnaces (i.e., inert gas generators) are suitable for combustion, as the inert gas produced in such systems can be fully utilized.:handshake
It can be used as fuel, though it is not very economical. Ideally, a portion of the inert gas should be separated; if the main component of this inert gas is CO2, recovery through conversion reactions could be considered.
It is a gas containing 9% CO and 10% hydrogen, with the remainder being inert gases; the proportion of combustible gases is low, resulting in a low calorific value per cubic meter, so it is not very economical to use it directly for heating boilers. I agree with what was said above; measures can be taken and then utilized.
Personally, I think it can be used in small hybrid combustion furnaces
The previous set of small hydrogen extraction units was used for H2 purification.
The content of flammable gases is less than 20%, the calorific value is low, and the transportation conditions are stringent, among other issues. Personally, I don’t think it’s suitable as fuel; purification and separation could be considered.
After purification and separation, it can be utilized in a relatively economical manner
