Physical Characteristics:
Molecular formula: CO2
Density: 1.977kg/m3
Production method (industrial method): it is extracted and recovered from the feed gas, fermentation gas, lime kiln gas and flue gas during the production of synthetic ammonia and hydrogen. The purity shall not be less than 99.5% (volume).
Chemical Property:
In general, CO2 is stable, inert, non-toxic, non combustible and non combustion supporting. However, CO2 can also participate in some chemical reactions at high temperatures or in the presence of catalysts.
Application:
In nature, carbon dioxide is one of the most abundant chemical substances. It is a part of the atmosphere and also contained in some natural gas or oil field associated gas and ores in the form of carbonate. The carbon dioxide content in the atmosphere is 0.03% - 0.04%, and the total amount is about 2.75 × 1012 t, mainly produced by the burning of carbon containing substances and the metabolic process of animals. In all sectors of the national economy, carbon dioxide has a very wide range of uses. Its main uses are: as chemical raw materials; As a refrigerant; As inert medium; As solvent; As a pressure source; 14 Use of CO2; And other purposes.
Storage And Transportation:
Goods are stored and transported in liquid or solid form. There are three methods for sub packaging and transportation: non adiabatic high-pressure steel cylinder shipping; Low temperature insulated container shipping; Dry ice in bulk or in blocks.
