CO2 Production Plant

Leading Global Manufacturer of CO2 Production Plants

MOS Techno Engineers is an internationally recognized manufacturer and exporter of fully automated CO2 Production Plants. With decades of engineering excellence, we design, build, and commission highly efficient carbon dioxide gas plants for industrial and commercial applications worldwide.

Our systems are engineered to produce ultra-high purity, food-grade liquid CO2 safely and reliably. Whether you are in the beverage industry, chemical manufacturing, or agriculture, our turnkey solutions are tailored to meet rigorous international quality standards.

A CO2 gas plant is a compact, easy-to-operate, fully automated plant that runs on diesel, natural gas, or kerosene. CO2 plant runs with a controlled fuel combustion process that generates flue gas with high CO2 content. We have carbon dioxide production plants for every type and need. Our carbon dioxide production plants include Diesel Fired, Natural Gas Based, BioMass Based, and Charcoal-Fired Based CO2 Production Plant.

In the CO2 production process, a CO2 recovery plant plays a crucial role by efficiently capturing and purifying carbon dioxide emitted from industrial activities. This purified CO2 is then repurposed for commercial applications, such as beverage carbonation or chemical manufacturing, or stored for future use

MOS CO2 Plant is a fully automated liquid CO2 Production Plant that uses a low density liquid solution to produce the best quality food grade CO2 gas safely and efficiently. Industrial manufacturing of liquid CO2 is suited for carbonated beverages.

We have successfully commissioned heavy-duty CO2 plants across multiple continents, including Asia, Africa, the Middle East, and the Americas. By adhering to international manufacturing and safety protocols (ISO 9001:2015), our seasoned engineers ensure that every facility is seamlessly installed. We also provide comprehensive global support, offering onsite employee training, structured installation guidelines, and ongoing maintenance programs.

CO2 Production & Purification Process

Our proprietary CO2 generation process guarantees seamless operation, maximum yield, and uncompromised safety:

1. Controlled Combustion: Fuel is burned under precisely controlled conditions.
2. Scrubbing & Absorption: After water and soda ash scrubbing to remove sulfur (SO2) contents, the flue gas is absorbed into a highly efficient lean MEA solution.
3. Stripping & Purification: The rich solution is heated to release raw CO2 gas. It is then fed through a vertical, oil-free compressor and a high-pressure potassium permanganate purifier.
4. Drying & Filtration: The gas passes through an automatic double-column molecular sieve drier and an unactivated carbon filter (iV 1100 grade) to remove any trace odors or aldehydes.
5. Liquefaction & Storage: Finally, the purified gas is fed into an R404a refrigeration loop and condensed into liquid CO2, ready for bulk cryogenic storage.

Utility Requirements for Various Capacities

Key Benefits of Choosing an MOS CO2 Plant

• Flexible Layouts: The modular, compact design allows for rapid installation and maximizes space utilization for both indoor and outdoor setups.
• Inline Scrubber Water Treatment: Recycles, neutralizes, and cools scrubbing water in a single closed-loop circuit, minimizing wastewater and reducing operational costs.
• Dry Running CO2 Compressors: Specifically engineered for CO2 gas, ensuring zero risk of oil contamination in your final product.
• High-Pressure Stainless Steel Purifier: Extended residence time provides ultra-efficient removal of NOx and H2S.
• Advanced Carbon Filtration: Guarantees a 100% pure, odor-free CO2 gas stream entering the liquefier.

How is Food Grade co2 produced commercially with Ultra High Purity

CO2 Gas is commercially produced by fuel combustion process through burning natural gas to separate the carbon and hydrogen atoms. In CO2 manufacturing plant purification and liquefaction process of Food Grade carbon dioxide manufacturing occurs in multiple stages. Post-compression CO2 at 16.5 bar is fed in the Dual Activated carbon towers at high pressure. The purification is more efficient. The activated carbon is iV 1100, which removes any odor and aldehydes in the CO2 manufacturing gas stream. 

The towers work cyclically after a pre-set cycle time, and the towers get switched over through a PLC-based control system and a set of changeover valves. With this, the second tower comes into operation, and the first tower undergoes simultaneous regeneration. 

The regeneration is accomplished by steam produced by an electric steam generator supplied with the equipment. The resurrection is essential to remove the impurities from activated carbon by steam washing. This cycle of tower changeover is repeated infinitely, and purified CO2 gas is available at the outlet.

In CO2 production plants, automation panels play an important role, these panels ensure the seamless operation of a continuous process that is efficient, remarkably reliable, and safe. The CO2 generated through this advanced system consistently meets international food-grade quality standards.

CO₂ Gas Plant

CO2 gas plant is a CO2 Production Plant that offers high food grade with high production capacity ideally suited for beverages, plastics, fertilizers, and rubber, among other industries. A set of comprehensive installation and operation manuals is supplied to ensure structure and future operation and maintenance are carried out efficiently and correctly.

The automation system, controlled by the PLC control panel, meticulously oversees and directs the intricate processes of CO2 generation. It regulates machinery, monitors parameters, and ensures precise control for optimal efficiency, reliability, and safety.

Cooling System:  This is an Optional cooling of water recirculation system to handle all the process cooling water.

MOS plant mainly comprises equipment like:

• Fully-Automatic CO2 Dehydrator System
• CO2 Liquefying System
• Interconnecting Piping
• Motor Control Center with Control Panel
• Water cooling tower with accessories with dual pumping Systems.

The fuel burned under precisely controlled conditions. After water/soda ash scrubbing, CO2 from the flue gas is absorbed into a solution heated by the combustion process to release the raw CO2 gas.

The CO2 obtained is then led to a vertical, two-stage, dry-running (Oil-Free) compressor and onto the high-pressure potassium permanganate purifier.

After drying in an automatic double-column molecular sieve drier, the CO2 receives final purification in an unactivated carbon filter before feeding into an R404a refrigeration loop in the liquefier. This CO2 Production Process can then provide the pure, liquefied CO2 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 world‘s top gas companies and soft drink and beer brands in over 100 countries.

CO₂ Generation Plant

The CO2 generation system is based on extracting the CO2 gas from the flue gases after combustion. The CO2 flue gas is washed in a DCC Tower with soda lye to separate the Sulfur (SO2 ) contents and for cooling and cleaning the flue gas.

The liquid carbon dioxide is now led to the absorber tower, where the lean MEA solution absorbs the CO2 contents of the flue gas and the residue gas, which is exhausted to the atmosphere.

The rich solution is fed to the stripper tower through a pump and a PHE to preheat it. The CO2 gas from the stripper is cooled and led to a series of purifiers system to remove the impurities and compressed in a non-lubricated two-state compressor to a pressure of less than 17.5 kg/sq. The CO2 liquid is then stored in a CO2 liquid storage tank.

Liquid CO2 Production

Low-pressure liquefied gas is another process of collecting CO2 and is provided either by developing high-pressure CO2 to a lower pressure or by freezing. CO2 gas is then injected in specially formed storage containers, gradually insulated, and outfitted with cooling assemblies to endure the physical storage pressure at or under 21 bar (304,58 psi) and -18 °C (-0,4 °F) temperature.

Pressure switches are connected to constrain the cooling units, and safeguard mechanisms and digital alert systems are outfitted to deliver the tank pressure and put an alert in the case of a cooling failure.
