Introduction
Ammonia (NH3) is a colourless, highly toxic gas with a pungent odour. It is a non-flammable gas at low concentrations (less than 15% by volume in air), but it can become flammable at higher concentrations. It is also corrosive and can cause serious health problems if inhaled.
Hazards
This gas presents several serious hazards. It can pose a fire and explosion risk, becoming flammable at concentrations above 15% by volume in air, and may also explode when combined with other flammable gases such as hydrogen (Hâ‚‚) or methane (CHâ‚„). In addition to this, the gas is corrosive to metals, meaning it can degrade and damage equipment over time. From a health perspective, exposure to high concentrations can lead to respiratory issues including coughing, wheezing, and shortness of breath. It may also cause eye irritation, skin burns, and have adverse effects on the central nervous system.
Applications of Ammonia
Whether in its liquid or gas form, ammonia is a common industrial chemical which is used in a variety of applications across a wide range of sectors. Its main uses include:
- Solvent
In its liquid form, ammonia can be used as a cleaning solvent that dissolves ionic compounds such as nitrites and alkali metals like calcium and barium. - Fertiliser
It is an important crop nutrient. It can be added to fertiliser solutions in wheat and maize farming, for example. - Refrigerant Gas
Ammonia gas is commonly used in refrigerators, as it is eco-friendly. - Water Purification
Liquid ammonia is a common drinking water treatment. - Plastic Manufacturing
Ammonia is used to produce some types of plastic. - Pharmaceutical Production
It is frequently used in the pharmaceutical industry as a disinfectant or a neutralising agent to inhibit the proliferation of bacteria. - Clinical Applications
In medical contexts, this gas is commonly used to prevent loss of consciousness and fainting. - Oil and Gas Processing
Ammonia is sometimes used during oil and gas production to neutralise acidic compounds. - Mining
In the mining industry, this chemical is used to extract metals such as nickel and copper. - Energy Production
Coal and oil-fired power stations use ammonia in their reactors to detoxify nitrogen oxides in the smoke, turning them into nitrogen and water.
