PROJECT DESCRIPTION

Premise

During the alcoholic fermentation process of wines, enormous quantities of carbon dioxide are produced. To get an idea of the quantities involved, just think that for every liter of wine produced, an average of 50 liters of carbon dioxide are produced. 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. The advantages that can be obtained by recovering and reusing carbon dioxide are various:

 

Better quality of wines produced

In order to obtain wines with ever greater organoleptic qualities, modern winemaking practices involve the manipulation of grapes, musts and wines in an inert atmosphere. Many wineries are equipping themselves with systems to manage production processes in an inert atmosphere. Having enormous quantities of carbon dioxide at harvest allows winemakers to apply reduction processes in all winemaking practices that benefit from this technique.

 

Rapid return on investment

The low cost of the recovery plant and the better quality of the wines obtained allow for 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 with 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 cellar

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 grapes from the receiving tanks to the pressing.
  • Pressing and destemming of the grapes.
  • Transfer of the crushed or destemmed grapes to the presses, macerators or fermenters.
  • Inertization of presses and must collection tanks.
  • Transfer of musts from presses to fermentation tanks in an inert atmosphere.
  • Inertization of all the phases of racking of musts and wines that take place during the harvest.

 

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, a decision will be made on how many tanks to include the capture. Galileo automatically recovers the carbon dioxide, treats it to eliminate any impurities and stores 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 inerting practices of the production processes. These large quantities of gas are also dispersed into the atmosphere.

 

The reuse of the gas produced by fermentation reduces the quantity of gas dispersed into the atmosphere with an undoubted ecological advantage.

 

Workplace safety

During the harvest, carbon dioxide from fermentation is dispersed in the same work environments. These environments therefore become dangerous for the cellar personnel. Recovery and reuse through channels designed to safely manage the entire process allow for an improvement in the quality of the work environment and therefore the safety conditions of the personnel involved in the processes.
