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.
Deposition process is the opposite of sublimation and gaseous carbon dioxide changes state into solid directly at -78.5 degrees Centigrade at atmospheric pressure. The density varies diversely but it commonly ranges between 1.6 and 1.4 grams per centimeter cubed. Since its dipole moment is zero, it has very low electrical and thermal conductivity. This solid also goes by the names of cardice or card ice in Britain.
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.
Some of the gas undergoes vaporization when pressure is reduced. As vaporization goes on, a significant drop in temperature takes place in the liquefied liquid left in the container causing a change in state to solid. The resulting solid might then be shaped into pellets or blocks of variable sizes. Blocks can weigh as high as 30kgs whereas pellets have a diameter of around one centimeter. Pellets have a cylindrical shaped.
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 applications of dry ice is very long and inexhaustible. Most of the applications relate to cooling and preservation of products. The product has good cooling capabilities because of its ability to sublime and the low temperatures involved. The uses span from residential to commercial, scientific, and industrial applications. In the car industry for example, it is used to free water in valveless pipes to allow for repairs and maintenance.
The pellets of this product are also used for blast cleaning. Small pellets are propelled onto surfaces to eliminate old paint, ink, dirt, rubber, mold, and oil among others. It is useful when residue from the cleaning medium is not needed. At home, cardice forms an ingredient in several recipes.
