Uses of Carbon Dioxide

Carbon dioxide is one of the valuable gases with large number of uses. For example carbon dioxide is use to make chemicals, refrigeration system, inert agent for packaging, beverages, welding systems, fire extinguishers, water treatment, horticulture, precipitated calcium carbonate for the paper industry and many other application. Large groups of carbon dioxide are also used to make the ozone layer thinner and for enhanced oil. Now days carbon dioxide is improved by making carbon dioxide from synthetic fertilizer and hydrogen plants or using either a chemical or physical solvent scrubbing system synthetic fertilizer and hydrogen plants, using either a chemical or physical solvent scrubbing system. Sometime carbon dioxide is made out limekilns, such as those used in the production of sodium carbonate and alcoholic drinks. Now this involves the heating of limestone. In some parts of the world, such as the United States, Italy, Norway and Japan, some carbon dioxide is extracted from natural carbon dioxide wells. A large proportion of all CO2 recovered is used at the point of production to make further chemicals of commercial importance, chiefly urea and methanol. The CO2 recovered for other commercial uses is purified, liquefied, delivered and stored mostly as a liquid, typically at 20 bar and –18°C table.
