This product is one of the most important products and has a high demand in the market in different industries for its features. Carbon dioxide (CO2) is a slightly toxic, odorless, colorless gas with a slightly pungent, acid taste. Carbon dioxide is a small but important constituent of air. It is a necessary raw material for most plants, which remove carbon dioxide from air using the process of photosynthesis. Carbon dioxide is formed by combustion and by biological processes. These include decomposition of organic material, fermentation and digestion. As an example, exhaled air contains as much as 4% carbon dioxide, or about 100 times the amount of carbon dioxide which was breathed in. Large quantities of CO2 are produced by lime kilns, which burn limestone (primarily calcium carbonate) to produce calcium oxide (lime, used to make cement); and in the production of magnesium from dolomite (calcium magnesium carbonate). Other industrial activities which produce large amounts of carbon dioxide are ammonia production and hydrogen production from natural gas or other hydrocarbon raw materials. Carbon dioxide is commonly used as a raw material such as: production of various chemicals; in fire extinguishing systems; carbonation of soft drinks; freezing of food: poultry, meats, vegetables, fruit chilling of meats prior to grinding; refrigeration maintenance of ideal atmospheric conditions during transportation of food products to market; enhancement of oil recovery from oil wells; Treatment of alkaline water.
