Industry involves the use of various gases which are not usually isolated in the atmosphere. CO2 is one such gas. It is present in the air, but at an extremely low concentration. It forms about 0.05% of the earth's atmosphere. This may seem insignificant, but it is not. CO2 is one of the most important gases in the atmosphere and so using a high pressure CO2 pump involves knowing more about it.
As a gas, CO2 has no smell or color. It is therefore impossible to detect by human senses. In its frozen form, it is known as dry ice, and it is used in cooling applications. However, it soon evaporates once exposed to the ordinary atmosphere. It is therefore difficult to store or trap CO2 in this form.
Carbon and oxygen combine to form CO2. This takes place during normal burning, or combustion. The carbon dioxide molecule, as its name indicates, is made up of one carbon atom and two oxygen atoms.
The process of photosynthesis might be familiar to people. Plants and trees exhibit this process during the day, when the sun is shining on them. Photosynthesis uses carbon dioxide as an input material and produces oxygen as a by-product. The CO2 is taken up directly from the air. But at night, the opposite happens and plants produce carbon dioxide gas. This is why people sometimes raise opposition to deforestation. The main forests of the world are important sources of atmospheric oxygen and they also eliminate massive amounts of CO2.
This means that even though carbon dioxide is present in such a small concentration in the air, it is highly important. It is also potentially lethal because it cannot be used by the human body. It is exhaled together with water vapor when you breathe out. If the air is made up entirely of CO2, it will cause death through asphyxiation instantly.
This is linked to one of the main uses of CO2, which is known as controlled atmosphere storage, or CA storage. In such facilities, the air is almost entirely carbon dioxide, and fresh produce does not decompose, since aerobic bacteria cannot function. The nutritional value of the produce is not always stable over time, though.
Another application of CO2 is in carbonated drinks, or soft drinks. This is obvious and well known, but there is an aspect of this technique that is not advertised and which is not always known to the consumer of these products. CO2 dissolves easily in water to form a weak acid known as carbonous acid (H2CO3). This acid forms and disappears as the fizzy bubbles dissolve and re-evaporate. Leaving a tooth in a soft drink overnight will cause it to dissolve, so that it won't be there the next day.
Carbon dioxide is not a gas that should be handled lightly by people. In high concentrations it can cause death through suffocation. Those who make use of high pressure pump equipment should therefore be aware of its nature and how to observe the proper precautions.
