Carbon dioxide is both a product of energy (related power and chemical projects) and a product which is consumed in numerous energy-related applications, some of which are critical in the production of oil and gas.
According to some surveys, when further defining CO2 applications in industry, much of the market is energy-related, at large. This is true when further considering CO2 as a cryogen in freezing applications, since with this large sector often 40% of the merchant gas business in the developed markets, could be viewed as energy related.
Energy related, as for cryogenic freezing applications, in lieu of cryogenic freezing the alternative could be mechanical refrigeration, a high energy-consuming form of refrigeration. On the other hand, with this article, I am strictly defining the more direct by-product or off-gas from energy projects, as well as the major CO2 consuming markets in the energy production sector.
Carbon Dioxide from energy production
CO2 from flue gas can be as basic as the simple combustion of wood in a fireplace; however I am reviewing larger commercial projects which yield CO2 as a flue gas, when speaking of this subject. With respect to this sector, some good examples include commercial cogeneration projects which yield CO2, and a slipstream of this flue gas is recovered, liquefied and purified to meet food standards in US, and other international projects.
