Abstract

Safeguarding the environment is one of main duties that industrial countries have to respect. Specifically, there is the problem of the greenhouse effect caused by CO2 emissions in the atmosphere from human activities. The CO2 is the main greenhouse gas emitted by fossil fuel combustion and causes global warming. With regard to this important environmental problem, the present paper has the main purpose of showing that it is possible to get \“clean-work” from power plants if the post-combustion CO2 separation process from the exhaust flow is made before that same exhaust flow is emitted into the atmosphere. Also, the paper shows that the post-combustion CO2 separation process is beneficial as the additional CO2 emissions caused by the separation process is compensated by the capture of a lot of post-combustion CO2 from the exhaust flow. Furthermore, the paper shows the main problems of the CO2 (gas, liquid, solid) stocking in full safety with respect to human health and environment. Keywords: CO2 emissions, separation process, stocking, human health safety. 1 Introduction Many industrial combustion processes are concerned with gas emissions in the atmosphere. Among these gases, CO2 is a greenhouse gas having an estimated radiative forcing equal to 4.37 (W/m2) for a CO2 doubling and it causes 60 % of the earth’s global warming [1]. To reducing this environmental problem we need to minimize CO2 emissions into atmosphere. This is achievable if there are plant solutions that involve the post-combustion CO2 separation process and its subsequent stocking in full safety with respect to human health.
