Detecting Ammonia Toxic Gas
Ammonia (NH3) is emerging as a promising carbon-neutral fuel for compression ignition (CI) engines, offering a potential solution to reduce greenhouse gas emissions in the transportation and power generation sectors. This colourless gas with a pungent odour is gaining attention for its ability to power engines without producing carbon dioxide emissions.
What is Ammonia?
Ammonia is a compound consisting of one nitrogen atom and three hydrogen atoms (NH3). At room temperature and standard pressure, it exists as a gas with the following properties:
- Molecular weight: 17.03 g/mol
- Boiling point: -33.34°C (-28.01°F)
- Melting point: -77.73°C (-107.91°F)
- Density: 0.73 kg/m³ at 25°C (77°F)
Where is Ammonia Used?
Traditionally, ammonia has been widely used in:
- Fertilizer production
- Refrigeration systems
- Cleaning products
- Pharmaceuticals
However, its potential as a fuel for CI engines is now being extensively researched and developed. Ammonia can be used in:
- Marine propulsion systems
- Power generation plants
- Heavy-duty vehicles
- Agricultural machinery
Where is Ammonia Found?
Ammonia can be sourced through various methods:
- Industrial production: Most commonly produced via the Haber-Bosch process, combining nitrogen from the air with hydrogen derived from natural gas.
- Green ammonia production: Synthesized using renewable energy sources, such as wind or solar power, to produce hydrogen through water electrolysis.
- Natural sources: Small amounts of ammonia are found in nature, produced by the decomposition of organic matter.
Ammonia in Compression Ignition Engines
Ammonia offers several advantages as a CI engine fuel:
- Zero carbon dioxide emissions
- High energy density
- Existing infrastructure for production and distribution
- Potential for carbon-neutral fuel cycle when produced using renewable energy
Detecting Ammonia Toxic Gas; However, challenges remain:
- High ignition energy requirement
- Slower combustion rates compared to diesel
- Potential for increased NOx emissions
- Need for specialized fuel storage and handling systems
To address these challenges, researchers are exploring dual-fuel configurations, blending ammonia with small amounts of diesel or hydrogen to improve ignition and combustion characteristics.
Ammonia CI Engine Performance
| Parameter | Diesel | Ammonia-Diesel Dual Fuel |
| Thermal Efficiency | Baseline | Comparable or slightly lower |
| NOx Emissions | Baseline | Potentially higher |
| CO2 Emissions | Baseline | Significantly reduced |
| Unburned NH3 | N/A | Present, requires mitigation |
