Co2 recovery plants for brewery
Co2 recovery plants for brewery , Recovery units are designed to collect and utilize the CO2 generated during the brewing fermentation process.
The plant promotes a circular utilization of the brewery’s CO2 by recovering the CO2 from fermentation. It is collected, purified, liquefied, stored, and ready to be used in all steps of beer production.
As a complete CO2 recovery system, the plant reduces the brewery’s CO2 emission and gives a reliable and cost-efficient supply of CO2 – making your brewery more suited for the future.
CO2 Recovery Process Overview
CO2 collection
The raw form of CO2 is collected from the fermentation tanks using flexible hoses connected to the existing tank’s CIP/gas outlet and to one of the central CO2 collection stations connection points.
Each of the connection points is equipped with a bunging valve or a check valve, and a shut off valve to ensure individual and continuous system operation without risk of cross contamination. If individual fermentation pressures are needed, bunging devices must be used instead of check valves.
CO2 purification
The purification takes place in 3 steps before and after compression and liquefaction. The CO2 raw gas from the collection system is supplied to the foam trap where the foam is seperated. After the foam trap but before the CO2 gas reaches the compressor, 90% of the impurities like alcohol, other volatiles and aerosols, are removed in the water scrubber. After compression the gas is dried and further purified in aluminium oxide-based dehydrators, which also removes traces of remaining volatiles. The Dehydrator is duplicated and regenerates automatically by heating. If needed an activated carbonfilter can be installed for H2S removal. To remove incondesabler gases, the liquied CO2 is destilled in the HGMC patented condenser and in a small reboiler and stripper column.
Liquefaction
The CO2 is compressed to be liquefied for rectification and compact storage and unlike conventional CO2 compressors, The HGMC three stage CO2 Compressor provides up to 45 bar pressure, hence the CO2 condensation takes place at 0-5 degree Celsius. This makes it unnecessary to use a separate CFC or ammonia cooling systems, but a glycol, ice-water or alcohol coolant system can be.
The dry and compressed CO2 is liquefied in in the condenser using an external coolant source and the liquid CO2 is continuously distilled to ensure low oxygen content. Liquid CO2 is pushed with 35-40 bar pressure to the CO2 storage tank, where liquid CO2 expands to the storage tank pressure and temperature. Vaporized CO2 from the storage tank is sent back to the compressor.
CO2 Storage and usage
HGMC offers a wide range of storage tanks from 100 liters to 50 tons and all tanks delivered from DALUM is adapted for CO2 recovery including high pressure storage option to reduce vaporization, flash gas return function, seperate CO2 filling line for low loses, chiller option and integrated ambient or glycol regenerable vaporizers.
HGMC can also take care of nessecary filters, regulators and safety devices for userlines. For breweries filling sparkling water using recovered or industrial CO2, DALUM always recommend to use final polishing filters after vaporizer and line regulator as the final step before a sterile filter and usage.
HGMC also offer cylinder filling stations designed to integrate seamlessly with our CO2 recovery plants and storage tanks, the station ensures smooth transfer of recovered CO2 into individual cylinders for further use or distribution.

FEATURES
Recovery units are designed to collect and utilize CO2 generated during the brewing fermentation process. The highest quality CO2 produced to meet stringent market requirements is ensured by using appropriate washing and filtration techniques.
The use of the most modern structured packing in the scrubber column allows reducing water consumption to 0.25 kg per 1 kg of finished CO2, which is equivalent to a 75% reduction in specific water consumption compared to traditional installations.
PUR-D technology is a final purification process, by means of a distillation column rectification process, which, in the process of separating and removing non-condensable gases, can reliably guarantee a reduction in the residual content of O2 < 5 ppm (volume) with a CO2 volume fraction of at least 99.998% .
The electrical system of the CO2 recovery unit consists of a decentralized electronic control panel and a low voltage power cabinet. The state-of-the-art electronic control panel allows you to monitor and control the operation of the unit in a color touch screen menu for easy access and trouble-free operation.
The unit starts automatically in sequence, and automatically maintains the operating mode. The whole process is easily monitored on the operator’s panel monitor, showing the status of the drives, readings of all sensors and alarms, which also have an audio accompaniment. All node-mounted instrumentation and A instruments are shipped unplugged at the factory and connected to remote module boxes.
The units are designed to provide the highest efficiency in 24/7 operation, durability, and the availability and reliability of individual components.
