Industrial liquid carbon dioxide GB / T6052-93 CO2≥99.9% (excellent products) CO2≥99.5% (first grade) CO2≥99.0% (Qualified) welding of carbon dioxide HG / T2537-93 CO2≥99.99% (excellent products) CO2≥99.95% (first grade) CO2≥99.95% (qualified product) food additive liquid carbon dioxide (fermentation) GB1917-94 CO2≥99.8% (excellent products) CO2≥99.5% (qualified product) food additive liquid carbon dioxide (lime kiln gas and ammonia method) GB10621-89 CO2≥99.5% Physical characteristics: Formula: CO2 Density: 1.977kg / m3 production methods (industrial method): from ammonia, hydrogen production process feed gas, fermentation gas, kiln gas and flue gas extraction and recovery, purity not less than 99.5% (by volume). Chemical properties: Under normal circumstances, CO2 stable, inert, non-toxic, no burning, no combustion. However, at high temperatures or presence of a catalyst, CO2 can also participate in a number of chemical reactions. Applications: In nature, carbon dioxide is one of the most abundant chemical substances, as part of its atmospheric composition, is also included in some natural gas or associated gas in oil and minerals present in the form of carbonate. Carbon dioxide levels in the atmosphere inside is 0.03% -0.04%, a total of about 2.75 × 1012 t, mainly by metabolism burning carbonaceous materials and animals. In various sectors of the national economy, carbon dioxide has a very wide range of uses. Its main uses: as chemical raw materials; as a refrigerant; as an inert medium; as solvents; as a source of stress; and other uses; 14CO2 purposes. Storage and transport: Storage and transport is liquid or solid form of goods carried. There are three methods of dispensing transport: non-adiabatic pressure cylinders shipment; cryogenic insulated container shipping; bulk or blocks of dry ice equipment.
