Vaporisation du CO2 liquide et économies d'énergies

摘要

Liquid CO_2 users who need to vaporize this molecule before application like soft drink carbonation, water pH control, modified atmosphere packaging, plants photosynthesis in greenhouses are using mainly electrical heaters. It is possible to install asystem to capture CO_2 vaporization energy in order to use it for water refrigeration, therebysaving operating energy cost and reducing the carbon footprint as well. The process is consisting in circulating water in a shell tube exchanger to vaporize CO_2. Typical example of a plant operating in a temperate climate for a more than 1000T C02/yearhas a two years payback approximately.
