Detecting Ammonia Toxic Gas

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: 

1. Industrial production: Most commonly produced via the Haber-Bosch process, combining nitrogen from the air with hydrogen derived from natural gas. 

1. Green ammonia production: Synthesized using renewable energy sources, such as wind or solar power, to produce hydrogen through water electrolysis. 

1. 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
