Dry ice refers to carbon dioxide gas that has been turned into solid state by being subjected to very low temperatures for long enough. Its major application is as a cooling agent. To get a deep understanding on the applications and manufacturing process of dry ice Columbus Ohio is the best place to check out. This article describes general properties, manufacturing process, and applications of this substance in real world applications.
Solid carbon IV Oxide has a similar chemical formula with carbon dioxide gas, that is, CO2. This formula means that there is a single atom of carbon bonded to two atoms of oxygen. It has a slightly acidic taste and it is colorless and non flammable with a sour zesty odor. At pressures below 5.13 atm and temperatures below -56.4 degrees Centigrade, the solid sublimes directly into a gas without going through the liquid state.
The opposite process of sublimation is called deposition and carbon dioxide gas changes state directly into solid at a temperature of -78.5 degrees Celsius at atmospheric pressure. The density is a variable component but ranges between 1.4 and 1.6 grams per cubic centimeter. Since it has a dipole moment of zero, electrical and thermal conductivity are very low. In Britain this solid is also referred to as cardice or card ice.
There are several methods that can be used to produce cardice on large scale. The first step involves producing gases that contain CO2 gas in large amounts. Commonly used methods include large scale fermentation and manufacture of ammonia from nitrogen or natural gas. Once carbon dioxide-rich gas is produced, pressurization and refrigeration are used to liquefy the gas.
The pressure is then lowered to cause some gas to vaporize. As the vaporization happens, a significant drop in temperature of the remaining liquefied liquid occurs causing it to turn into solid. The formed solid can then be compressed into variable pellets and/or blocks of variable sizes. The blocks can be as heavy as thirty kilograms while the pellets are small, about a centimeter in diameter and cylindrical in shape.
There are safety concerns associated with handling of this solid product. For example, severe skin damage can result through frostbite from prolonged exposure. It can also pose a risk of hypercapnia because small amounts sublimate into large quantities of CO2 gas. Exposure must therefore only happen in areas with proper ventilation. In the US, there are several regulations regarding transportation by road, water, and air of this product. Packaging is also done in specifically designed containers.
The list of places and uses dry ice can be put to is inexhaustible. Most applications are related to cooling and preservation. Cardice is a good coolant because of its sublimation property and low temperatures. The uses are in commercial, scientific, industrial, and residential applications. For example, in the auto industry, it is used in freezing water in valve-less pipes for repairs and maintenance to be done.
Blast cleaning is also a major application of this solid. Small pellets of the solid are propelled at surfaces to remove dirt, old paint, ink, rubber, oil, and mold among others. It is particularly useful in cleaning applications where residues from the blasting medium are not required. In homes, several recipes include cardice.
