PROJECT DESCRIPTION

Premise

During the alcoholic fermentation process for the preparation of beer, enormous quantities of carbon dioxide are developed. To get an idea of the quantities involved, just think that for every liter of beer produced, approximately 25 liters of carbon dioxide are developed. Normally all this gas is dispersed into the atmosphere with obvious ecological and economic damage. The patented Galileo system allows the recovery of fermentation carbon dioxide and the advantages that can be obtained by recovering and reusing carbon dioxide are various:

 

Better quality of beers produced

Modern practices require working in an inert atmosphere, therefore many breweries are equipping themselves with systems to manage production processes in an inert atmosphere. Having huge quantities of carbon dioxide during processing allows Master Brewers to work in a protected environment, obtaining enormous advantages in the quality of the final product. The recovered CO2 is much more effective than nitrogen in reducing the oxidation of the beer.

 

Rapid return on investment

The low cost of the recovery plant and the better quality of the beers obtained allow a rapid amortization of the costs of the plant. Furthermore, recent legislation on environmental protection provides for a tax system that in the future will increasingly penalize production units that determine carbon dioxide emissions. By adopting a gas recovery system, it will be possible to access tax breaks that will help accelerate the recovery of the investment.

 

Where to use la CO2 in the brewery

The carbon dioxide recovered and stored at high pressure can easily be used to manage the following processing phases in an inert atmosphere:

 

• Inertization of the must and beer receiving tanks;
• Transfer of wort and beer from one tank to another in a protected environment;
• Pressurization of beer storage tanks;
• Inertization of all bottling phases and balancing of the fermenter back pressures;
• Addition of Carbon Dioxide to beer as required.

 

Ease of installation

The Galileo system consists of a carbon dioxide capture system that is installed directly on the fermentation tanks. Based on the calculation of the requirement, it will be decided how many tanks to provide for the capture. Galileo provides, in a completely automatic way, to recover the carbon dioxide, to treat it to eliminate any impurities and to store it in special high-pressure containers.

A simple distribution system allows the carbon dioxide to be conveyed from the high-pressure containers to the various users that the customer intends to serve. This system can also be managed automatically. The entire system is built “turnkey” by Enomet.

 

Ecological aspect of the process

Carbon dioxide from fermentation is usually dispersed into the atmosphere and at the same time, large quantities of carbon dioxide are purchased, in cylinders or in the form of dry ice, to manage the practices of inerting the production processes. These large quantities of gas are also dispersed into the atmosphere. The reuse of the gas produced by fermentation decreases the quantity of gas dispersed into the atmosphere with an undoubted ecological advantage.

 

Workplace safety

Carbon dioxide from fermentation, during processing, is dispersed in the same work environments. These environments therefore become dangerous for the personnel. Recovery and reuse through channels designed to safely manage the entire process, allow to improve the quality of the work environment and therefore the safety conditions of the personnel involved in the processes.

We design and build small, medium and large fermentation CO2 recovery systems, suitable for the needs of every type of customer.
