Which Gas is Called Blue Gas?
Water-gas is called blue gas.
Water-gas, also known as blue gas, is a significant industrial fuel gas. This gas is recognized by its specific production method and composition, playing a role in various industrial applications as both an energy source and a chemical raw material.
Understanding Water-Gas (Blue Gas)
Water-gas is a manufactured gaseous fuel that primarily consists of a mixture of carbon dioxide and hydrogen. It is not a naturally occurring gas but is produced through an industrial chemical process.
Composition of Blue Gas:
- Carbon Dioxide (CO₂): A non-combustible component of the mixture.
- Hydrogen (H₂): The primary combustible component, which contributes to the gas's energy potential.
Production Process of Blue Gas
The production of blue gas (water-gas) involves a specific high-temperature reaction. This process is crucial for generating the gas for industrial use.
Steps in Production:
- Raw Materials: The process utilizes steam (H₂O) and red-hot coke (a form of carbon, C) as primary inputs.
- Endothermic Reaction: Steam is passed over the red-hot coke, initiating an endothermic reaction. This means the process absorbs heat from its surroundings to proceed, requiring continuous heat input to sustain the reaction.
- Resulting Mixture: The chemical reaction yields a gaseous mixture comprising carbon dioxide and hydrogen.
Key Characteristics of Water-Gas
Water-gas possesses several important characteristics that define its utility in industrial contexts:
- Alternative Name: It is commonly referred to as blue gas.
- Composition: A blend consisting of carbon dioxide (CO₂) and hydrogen (H₂).
- Production Method: Produced by passing steam over red-hot coke.
- Reaction Type: The production process is an endothermic reaction, meaning it consumes heat.
- Calorific Value: Water-gas has lower calorific values than coal gas. This indicates that it releases less heat energy per unit volume upon combustion compared to coal gas, another widely used industrial fuel.
For a quick overview, here's a summary of its key features:
| Feature | Description |
|---|---|
| Alternative Name | Blue Gas |
| Composition | Mixture of Carbon Dioxide (CO₂) and Hydrogen (H₂) |
| Production Method | Passing steam over red-hot coke |
| Reaction Type | Endothermic |
| Calorific Value | Lower than coal gas |
