General information about CO2What is CO2?Carbon dioxide is the combination of two atoms of oxygen joined with a single atom of carbon. Its chemical formula CO2, is almost as well known as that of water, H2O, and it is frequently referred to by its formula rather than its name. In natures chain of life, the mutual dependence of plant and animal life is maintained through the link of carbon dioxide. Every time we breathe we release this gas which plants need for life. Through the process of photosynthesis, the plants separate the carbon from the oxygen. In turn, plants release the pure oxygen which we need to survive. We reverse the process, and by combining the oxygen with carbon from the foods we eat, produce carbon dioxide again. CO2 is a colourless, inert gas approximately 1 times heavier than air and 0.03 % is present in the earths atmosphere. It smells slightly pungent, has a sweet biting taste (soda water) and is highly stable (difficult to separate). It is produced in varying amounts by the common process of combustion of fuels high in carbon content. The most common source of fuel for combustion is oil which, when mixed with the correct proportion of air, burns to produce around 15 % CO2 in the flue gases of a CO2 plant. After combustion has taken place, the CO2 can be separated from the flue gases and, through a simple process, made available for the many commercial purposes to which it can be applied. CO2 can exist in three forms: - in gaseous form - in liquid form - in solid form (for the beverage and food industries) (in a storage tank under pressure) (called dry ice, for cooling, blasting etc.)

GASEOUS CO2 can be liquefied under pressure provided its temperature is below 31 C, this temperature being referred to as the CRITICAL POINT. If compressed and cooled below the critical point, a colourless fluid, approximately the same density as water, is produced. CO2 will remain in the liquid form as long as its temperature remains below the critical point but will return to the gaseous state if its temperature rises above this point, regardless of the pressure applied. LIQUID CO2 can be stored indefinitely at High pressure or Low pressure as follows: High Pressure CO2 High pressure liquid CO2 is produced by compressing the gaseous CO2 in multistage compressors to pressures in the neighbourhood of 69 bar pressure, then cooling it to around 18 C. It is customarily filled into specially constructed steel cylinders. Like water, liquid CO2 can be weighed, and this is the normal form of measuring it. Low Pressure CO2 Low pressure liquid is an alternative method of storing CO2 and is produced either by expanding high pressure CO2 to a lower pressure or by refrigeration. It is held in specially constructed storage tanks, heavily insulated and equipped with refrigeration units to hold the internal tank pressure at or below 21 bar and -18 C temperature. Pressure switches are incorporated to control the refrigeration units and safety mechanism and electrical alarms are fitted to release the tank pressure and raise an alarm in the event of refrigeration malfunction.

General information about CO2Low pressure liquid CO2 (sometimes referred to as bulk) is transported to one place from another in insulated road tankers or trailers (or, in some countries, by rail tank wagons), the liquid being simply transferred from mobile to static tank by pumping or gravity feed. Unlike water, carbon dioxide cannot exist in the open air in liquid form. It must be held under pressure or refrigeration (or a combination of both) to remain in the liquid state. SOLID CO2 (customarily known as DRY ICE) Dry Ice is the product of processing liquid CO2. If the pressure of liquid CO2 is suddenly released, a proportion of that liquid will change to the solid state (becoming dry ice snow) and the remainder will revert to gas (revert gas). When the snow is compressed under hydraulic or mechanical action, blocks or pellets of dry ice are formed. The revert gas (gaseous CO2) can be readily reclaimed and converted back to liquid by recompression and reliquefaction, thence returned to the dry ice block machine or pelletizer for further processing. The temperature of dry ice is -79 C and in the atmoshere it will pass directly from the solid to the gaseous stage, leaving no moisture or trace of its presence except the cold.

CO2 is our lifeMany generations - and individual lifetimes! - of experience have perfected ASCO s ability to provide the most complete and best matched CO2 system available. From the CO2 production or recovery plant through to storage, dry ice blasting, cylinder filling, dry ice making and even dry ice wrapping its all ASCO. This ability to provide matched components benefits ASCO clients as they can comfortably develop and grow their business without changing suppliers. Having the largest range of CO2 and dry ice components also enables ASCO customers to make full use of the versatile nature of CO2 and its vast number of uses, thus gaining maximum value from the product. For example a soft drink bottler could easily develop an extra cash flow business from surplus CO2 (or excess plant capacity) by adding ASCO dry ice equipment and/ or cylinder filling gear to supply CO2 to other users. ASCO s website provides details of their most up to date CO2 and dry ice plants. All ASCO equipment is space efficient, designed for easy operation maintenance and engineered for maximum reliability and life. Component materials are selected to balance capital cost and plant longevity and from the flue gas oxygen sensor on the plant to the level indicator on the CO2 storage tank all controls are effective, logical, clear, and linked to a PLC. ASCO s technology, combined with a wide range of CO2 equipment, makes it easy for their clients to mix and match components and thus tailor their CO2/Dry Ice System from the one shop. Significant new ASCO CO2 plant sales to Africa, Middle East, and South America, indicates that many bottlers, brewers and merchant CO2 companies prefer working with a single supplier and that supplier is ASCO. Let our life add life to your business.

General information about CO2From liquid CO2 into dry iceCarbon Dioxide has 3 physical states of gas, liquid and solid which depend on temperature and pressure. The relationship between the 3 states is shown on the pressure-temperature phase diagram beside.

Where does CO2 come from?CO2 is derived from a number of sources including combustion of carbonaceous fuels, fermentation, natural wells, and as a by-product of industrial processes such as ethylene oxide and bioethanol production and ammonia synthesis. CO2 phase diagram

The Solid State (Dry Ice)

Below the triple point (5.18 bar, - 56.6 C) CO2 can only appear in its solid and gaseous state. Dry Ice is the common trade name for solid CO2. At atmospheric pressure it has a temperature of approx. -79 C. The solid CO2 changes directly into its gaseous state. This evaporation (sublimation) does not leave any residues. Dry ice is non-toxic, non-inflammable, inert, without smell and bacteriostatic. It is white and has a density of approx. 1'500 kg/m3 in its compact state. Dry ice is an ideal refrigerant which qualifies especially well for various applications. It has a high cooling capacity and heat transfer is very high when in direct contact with the cold material.

ASCO has the best range of Dry Ice Machines for dry ice production.

The Liquid StateWithin a temperature range between -56.6 C and 31 C and pressure greater than 5.2 bar and less than 74 bar respectively CO2 is in its liquid state except at very high pressures. This means that, below 5.2 bar, CO2 exists only in its solid or gaseous state. At 5.2 bar and - 56.6 C all three states (solid, liquid and gas) are present. This is called the triple point. The critical point of CO2 lies at a temperature of approx. 31 C and a pressure of approx. 74 bar. Normal CO2 liquid can only be formed at temperatures below 31 C. Above the critical point there is no physical difference between the liquid and gaseous phase. This supercritical state is also called Fluid. The liquid state is important for the storage

General information about CO2and transportation of CO2 as well as during cooling and freezing applications. During release of the liquid CO2 to atmosphere a temperature of -79 C is reached. This is associated with a high cooling capacity due to the evaporation heat which is extracted from the environment when releasing the liquid CO2.

The Gaseous StateCO2 gas has a density of approx. 1.9 kg/m3 at atmospheric pressure, +15 C. CO2 has many unique and beneficial features which make it valuable inthe preservation of packaged food, in explosion and fire protection, in pest control and as protective gas in inert-gas-welding. In all these applications it is important for the CO2 gas to drive out and replace the atmospheric oxygen. Moreover, CO2 gas is used for enriching the atmosphere in greenhouses, in storing fruits and vegetables and for pH control when treating potable and waste water.

CO2 Production Plant Process Description The fuel is burned under carefully controlled conditions. After water/soda ash scrubbing, CO2 from the flue gas is absorbed into a monoethanolamine based solution which is subsequently heated by the combustion process to release the raw CO2 gas. The CO2 is then led to a vertical, two stage, dry running (oil free) compressor and on to the high pressure, potassium permanganate purifier. After thorough drying in an automatic twin tower molecular sieve drier, the CO2 receives final purification in an activated carbon filter prior to feeding into an R404a refrigeration loop in the liquefier. The pure, liquefied CO2 can then be fed to a bulk CO2 storage tank. This continuous process is efficient, reliable and safe. The CO2 meets international food-grade quality standards and is used daily by the worlds top gas companies, soft drink and beer brands in over 100 countries.

Special features of CO2 Gas Revert Recovery Systems:CO2 buffer balloon Specially designed, made of foodgrade acceptable material, to provide a constant back pressure to the dry ice machine as well as provide constant supply conditions of CO2 flow to the gas compressor. Local conditions may require reheating of the CO2 revert gas which can be supplied as required for each application. A two-stage, watercooled, dry running CO2 recompressor with separate cooler for each stage compresses the revert gas up to approx. 18 to 20 barg. Liquefies the compressed CO2 gas through a standard refrigeration loop. The reliquefied CO2 is then returned to the liquid CO2 storage tank for reuse in dry ice production. The special CO2 condenser utilized makes unsightly overhead condensers obsolete and offers greatly reduced footprint requirements. A central control system automatically controls the entire process and houses the electric motor distribution, starting, operator interface and PLC control system.

CO2 StorageTransportable CO2 Tanks

ASCO supplies different sizes of transportable (demountable) CO2 tanks which can be mounted on any suitable truck or drawbar trailer of the rigid flat type. Transportable tanks are a cost saving alternative to conventional road tankers as the operator may use the vehicle for other duties as well as bulk CO2 transport. The tank is a self-contained unit mounted on a base frame and when empty it can easily be craned on or off as required. Suitable lifting lugs are on the top of the tank. These transportable tanks can also be supplied with refrigeration systems which makes it possible to use them for the transport as well as for the storage of the liquid CO2. The special design allows simple operation. A lockable machinery compartment houses the transfer pump and motor, control valves, contents and pressure gauges, pipework and refrigeration system (optional).

CO2 Gas Dosing for Water NeutralisationCO2 Gas Dosing and Injection Systems

ASCO CO2 Dosing System (single line) Wherever you need to have an exact quantity of CO2 gas to be dosed, the ASCO CO2 Gas Dosing System is ideal! For the process-regulation you only have to provide a 4-20 mA input signal, the flow output signal will then also be within a range of 4-20 mA, all these signals can then be processed locally on the main DCS. The system is equipped with a CO2 pressure reducing valve, CO2 filter, CO2 gas flowmeter, CO2 regulating valve, pressure gauges, safety valves and a completely pre-wired electrical junction box. In case of maintenance the system provides a manual by-pass line, which also can be monitored by the flowmeter. Herefore, changing a CO2 filter cartridge or doing any other service work on the system is quick and easy! As raw and fitting material ASCO only uses stainless steel. This makes the system very resistant and extends the durability. Due to the special equipment used on the system no auxiliary power, e.g. compressed air, is necessary. Every process valve works with CO2 gas. Typically, the ASCO CO2 Gas Dosing System is used on desalination plants to neutralise the product water. Advantages of a CO2 Gas Dosing and Injection System: easy to install very accurate 4 - 20 mA output signal robust stainless steel construction typically used for desalination plants Site conditions Min. ambient air temperature: Max. ambient air temperature: Humidity: Wind speed max: Uniform building code: Temperature treated water: Side stream water pressure: 10 C, optional with heater for vaporiser down to 4 C 38 C, optional with air conditioned cabinet up to 50 C 34 % to 99 % 19.03 m/s, tank foundation must be recalculated by local civil engineer seismic zone 2A 15 to 35 C 4 bar max

Layout of a Double Line CO2 Gas Dosing System:

Layout CO2 gas dosing system (double line) with CO2 tanks and vaporisers ASCO provides a completely redundant system which automatically controls and regulates the CO2 flow depending on a set point coming from the LCP with integrated HMI. Depending on the condition of the storage tanks, vaporisers and the dosing systems, the system will detect and decide what parts need to take over the load to guarantee a continuous CO2 injection into the side stream water. Therefore, all automatically activated valves are equipped with positioning end switch (feedback) so that malfunctions will be detected. All operating conditions are displayed on the local HMI screen and are available as data bloc for customers PCS.
