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.
