An Integrated CO2 Production and CO2-NH3 Cascade Refrigeration System
Liquefied CO2 is used on a daily basis in the red meat industry to produce dry ice snow for product cooling applications. Traditionally, it has been cost prohibitive for abattoirs to invest in their own CO2 liquefaction equipment, and consequently, it is procured from specialist providers at a significant cost.
This project involved the development of a concept design for the integrated CO2 refrigeration and liquefaction system, along with investigations into its technical and financial feasibility. The model incorporated capital expenditure, operational expenditure and cost reductions expected, when integrating the CO2 liquefaction system.
