Co2 Application
Carbon Dioxide Gas Manufacturers in Coimbatore has been profound as the best manufacturing industry of gases. Carbon dioxide has numerous applications in usage of this gas. It includes various forms such as cooling the liquid and solid form in the refrigerator as an inert gas in a chemical process. Often Carbon Dioxide is used in various applications of casting molds to enhance their hardness which is used in the Metal Industry. This process of gas uses large production and quality of raw materials which maintains chemicals, pharmaceuticals, and petroleum industries. This Carbon dioxide gas is used for many purposes that might include Rubber, Plastic, and Beverage Food Items which is used for quick freezing that converts the mixture of Carbon dioxide widely.
Automobile Sector In welding
In the Shieding gas segment in the welding sector, CO2 is the largest consumption to providing better shielding gas to preventing welding property from the atmosphere impurities. Co2 is the best solution to the MIG welding application which provides the better shield to protect the welding parameter which can give the results of good penetration, No spatter, No pin holes and slag free welding.
Carbonation
CO2 gas is also used in the Beverages sector for carbonation process in the manufacturing of Beer, wine and soft drinks like soda water where its presence enhances the flavor and preserves the contents of barrels, bottles and other containers.
PH control of washing water
CO2 is used to lower the pH of process water which has been treated with alkaline sodium hypo-chlorite to maintain chlorine ppm. This results in improved microbiological control at reduced concentrations of hypo-chlorite in such operations as vegetable, salad and cress washing.
Water treatment in Desalination Plant
CO2 is used to increase the carbonate level in the water treatment plant in the Desalination segment. During the process, the Co2 is injecting middle of the process before delivery as per their formula to provide the good taste water.
SVCG offer the Lco2 with Storage terminals for their carbonate process at customer site. Normally we install 20Kl vessels to manage their entire gases requirement sophisticatedly.
Moving liquid by pressure
Considerable amounts of CO2 are used in the brewing industries, not only for carbonation but also in the conditioning and pressurized movement of beer and ciders. CO2 is also used for pressurized dispensing beer, soft drinks and ciders. In Juice industries, CO2 is also used for pressurized movement of fruit pulp.
Purging and inerting
CO2 is used in the purging of tanks and pipelines prior to their use of storage of beer, wine, edible oil and other consumables. It is also used as an inert atmosphere in storage tanks containing beer, wine, edible oil etc.; in order to minimize the oxidation.
Modified atmospheric packaging
By introducing CO2 into hermetically sealed' gas impermeable packs containing perishable foodstuffs, air is removed from the pack thus ensuring there is no oxidative degradation and any opportunity for the development of off-odors and flavors. The presence of high concentrations of CO2 also inhibits the growth of many aerobic and some anaerobic micro-organisms thereby prolonging the storage life of the products. Concentrations of CO2 as low as 10% have been shown to have a beneficial effect by reducing the growth rate of food spoilage moulds and bacteria; but generally speaking the CO2 concentrations should be as high as possible. CO2 modified atmosphere packaging, therefore, offers additional protection compared to vacuum and nitrogen packaging which are only effective by way of exclusion of oxygen.
Food freezing with Under storage
Following to rapid rise in energy cost in the last few years globally, the use of CO2 for freezing has become increasingly competitive with other expendable refrigerants which require a greater amount of power and high capital investment for their production.
When liquid CO2 is discharged into the atmosphere its physical properties dictate that it must instantaneously change to solid and gas, both at -109.20F.These are the only two forms of CO2 that can exist at atmospheric pressure and about 1kg. of liquid CO2 injected gives 0.5 Kg of CO2 snow which should absorb 228 BTU before it is completely converted into 1Kg.of gas at 109.20 F. Further in order to raise temperature of 1 Kg. Of gas at -109.20 F by 10 F, 0.4BTU has to be absorbed from the surrounding. Thus if the gas is rejected from the freezer at 00 F, it will have absorbed additional 43.6 BTU/1 Kg. of gas. So about 270 BTU can be removed to by 1 Kg. Of bulk liquid CO2, when gas is rejected at 00F, of which 84% is achieved by converting Sri Venkateswara Carbonic Gases Pvt. Ltd.. to gaseous CO2 at -109.20F.
All CO2 freezers work on the simple principal of injecting Liquid CO2 into the freezer through specially designed nozzles to ensure the rapid conversion of CO2 snow to CO2 gas. This action initially cools the freezer to operating temperature of, with circulation of cold gas by means of fans. During operation, as the temperature of the gas rises above the pre-set value, the thermostat operates, so activating the solenoid valve on the liquid CO2 & more liquid CO2 is injected with corresponding cooling.
Spiral freezers, Straight Tunnel freezers are available with capacities up-to 2 tons/hr. and for smaller scale Batch Freezers of capacity of about 150 Kg/hr. Liquid Dry Ice supply is maintained from bulk storage tank installed at customer's premises.
