2 Co2 Production Plant Process Description:- The fuel burned under careful control condition and under PLC Control panel. After water/soda scrubbing in DCC Tower/So2 Removal tower from the flue gas is absorbed in the monoethanolamine based solution in Absorber tower and then again in to the stripper tower which is subsequently heated by the combustion process to release the raw co2 gas. The carbon dioxide is the go the purification train generally known as PTK in which there is two KmNo4 Tower and other one is activated carbon filter if there and then it led to two stage vertical or horizontal compressor and then it goes to the high pressure pre-cooler and then in to the dryer. After through the dryer in an automatic dryer then goes to the liquefaction system generally screw compressor and R 404A is used as a refrigerant and after that pure and liquefied carbon dioxide can then feed to a bulk storage tank. This Continuous process is efficient, reliable and safe and also meets the international food grade quality standards and can be used in soft drinks companies, breweries and many more related sectors.

3 Features of Co2 Production Plant:- Components Details Co2 Generator Package Amine Regenerator So2 Removal Tower (DCC Scrubbers) Absorber Tower Features The purpose of the CO 2 Generator Package is to produce gaseous carbon dioxide. Air and a hydrocarbon fuel (Diesel or Natural Gas) are fed into a burner specifically designed for Diesel/ natural gas Fuel Firing and for a two-fold purpose. The first is to produce a flue gas consisting of carbon dioxide, nitrogen and water vapor by combustion of Diesel Oil. The second purpose is to produce the heat during combustion needed to regenerate the amine absorbing solution From the combustion chamber; the flue gas enters the flue gas cooler/so 2 scrubber where it is cooled to the desired temperature. Here the water entrained in the gas is also removed, and the gas proceeds to the absorber tower. In the absorber tower, the carbon dioxide is absorbed into the monoethanolamine (MEA) absorbing solution. The remaining vapors (N2, H 2O) vent to atmosphere through a stainless steel demister and centrifugal separator to minimize MEA loss. From the absorber sump, the rich MEA (loaded with CO 2) is then pumped to the stripper tower where the heat of combustion is used to release carbon dioxide in gaseous form at a controlled pressure. The carbon dioxide is cooled and ready for further processing in the purification, compression and liquefaction systems. The lean MEA, which is condensed from the CO 2 vapor, is returned to the absorber to minimize losses. The amine regene rator is a combination combustion chamber and heat exchanger specifically designed and manufactured for this service. It provides the means for the required flue gas containing CO 2, as well as the heat source for amine CO 2 stripping.. Combustion and return tubes are constructed of stainless steel. Reboiler constructed of certified boiler quality steel.. Filtered air is supplied by a heavy-duty blower.. Heavy duty burner is designed to accept a carefully controlled mixture of fuel and air to produce the flue gas and the heat for regeneration of the amine solution.. Flow devices are provided for air and fuel indication.. Fuel pump with strainer and controls is gravity fed from the customer supplied fuel oil supply.. Burner has a spark ignited gas fired pilot (LPG or Propane gas cylinder by customer). Automatic push-button ignition of the pilot and the burner are electrically interlocked and programmed for semi-automatic start-up.. Amine regenerator is of the dry back design complete with a flanged rear door.. Easy access for inspection and maintenance.. Front and rear access to the firing and flue gas return tubes. From the combustion chamber, the flue gas proceeds to the combination direct Contact flue gas cooler/ SO 2 scrubber constructed of stainless steel. This provides the necessary cooling of the flue gas, as well as removal of impurities such As SO 2. A stainless steel pump recalculates a soda ash ( Na2CO 3) solution to cool the flue gas and cleanse the flue gas stream of SO2 Stainless steel packing to provide necessary contact surface for cooling and scrubbing the flue gas. Counter flow design promotes efficiency and effectiveness. Automatic ph control system, including caustic day tank, circulating pump, plate and frame heat exchanger, valves, gauges, etc. Entrained caustic is removed by a stainless steel demister section. Absorber Tower is designed to provide the needed contact time between the flue gas and MEA solution for the most efficient CO 2 absorption. Tower contains two (2) separate polypropylene packed beds with distributor and redistributor to ensure proper liquid/gas distribution. Liquid/gas counter current flow through both beds ensures proper contact of the lean MEA with the flue gas. Specially designed demister for liquid/gas separation. Superior absorber efficiency with 0.2% CO 2 loss in the nitrogen vent stream directly relates to low fuel consumption and thus cost savings.

4 Stripper Tower The design of the stripper tower is such that it ensures that the MEA solution is stripped of all CO 2 so that the MEA lean loading is at its absolute minimum, thus assuring efficient absorption in the absorber tower. Rich MEA/solution steam counter current flow through bed ensures proper rich MEA/solution steam contact. Tower contains a packed bed of ceramic saddles with a stainless steel liquid distributor. Integrally mounted on amine regenerator to ensure maximum stripping efficiency. Co2 Compressor Co2 Compressor Specially designed for use with carbon dioxide. The CO 2 Compressor is a compact, easily installed, durable and smooth running machine. The compressor is a non-lubricated (oil- free), two (2) stage, double acting, stationary type machine, specifically designed for use with CO 2 applications where the slightest petroleum lubricant cannot be tolerated. Co2 Dryer Liquefaction Unit PLC Control Panel Co2 Dryer Dual tower desiccant type dryer with internal reactivation dries the CO 2 gas, thereby eliminating the formation of frost and possible freeze-up in the CO 2 condenser. Desiccant type, dual tower, electrically reactivated CO 2 Dehydrator. Outlet maximum dew point -40 C at 17.2 bar g. Towers are automatically alternated on a timed cycle with the off-stream tower being reactivated while the on-stream tower is drying the CO 2 gas. Automatic reactivating, purging, and cool down cycle. Coalescing pre filter is provided on the inlet side of the CO 2 dehydrator, ensuring liquid droplet-free CO 2 gas entering the desiccant beds. Desiccant Dust After filter is provided on the outlet side of the CO 2 dehydrator, ensuring dust- free CO 2 condenser operation. Manual Dew point Tester provided for regular checks on dew -point. Liquefaction Unit The CO 2 Liquefying System Package is designed to liquefy the CO 2 vapor at 17.2 bar g by cooling the vapor to -22 C, at which temperature it changes into liquid CO 2. The liquefying equipment is of the heavy-duty type and designed for continuous operation. All of the following components are completely piped and wired. The Motor Control Center supplied will be designed to include all motor starters required for the entire CO 2 plant mounted in one (1) central panel. A main disconnect/circuit breaker, voltmeter and power to control voltage transformer are supplied.
