Design of Carbon Dioxide Recovery Plant from Wort Fermentation for Preservation of Carbonated Drinks

This work presents the design of a plant to recover carbon dioxide from wort fermentation for preservation of carbonated drinks. The feed composition data was gotten from International Breweries Port Harcourt (Formally PABOD Breweries Plc) which has 95% CO2, 4% Ethanol and 1% water. The material and Energy balance, Equipment sizing, costing and simulation was carried with the help of ASPEN HYSYS which gave 99.9% CO2 purity that conforms with the standard for food beverage industries. The optimal process flow diagram for CO2 recovery from wort fermentation was determined using HYSYS and this has economic advantage of reduction in the cost of production without adverse impact on the purity of CO2. The plant designed with ASPEN HYSYS and simulated whose results when compared with manual results gave agreement. The design also involves unit operations (Gas separator, Gas washer, CO2 Storage tank and stripper) in terms of cost, production rate and profit maximization at given conditions of the various unit operations. Also, material balance for Gas washer, Gas separator and stripper to develop the models for the design parameters for the recovery of CO2 from wort fermentation was carried out using HYSYS.
