The Fight to Overcoming Greenhouse Effect for Anti Global Climate Change, and the Current Situation of that Fight

Nguyen D

Greenhouse effects are caused by the release of CO2 from industries, particularly from thermal thermal power plants with fossil fuels. According to scientists, CO2 emissions from thermal power plants account for nearly 50% of the global greenhouse effect, meaning that if we recover all CO2 from thermal power plants, Looks like it will be fixed. In industry today, it is unreasonable if using Ethanolamine to recover CO2, because the amine solution has many disadvantages, which is very expensive, resulting CO2 is a dirty CO2, The ethanolamine along with the adjuvants in the tower to form heat-resistant salts or to react with oxygen or other industrial dusts in the exhaust gas to consume a lot of solvent. Collection of CO2 for anti-global climate change has not yet achieved the desired effect, according to us for four reasons: 1. This is the main reason, because we do not have the suitable industrial equipment and technologies. 2. Because we have not fully treated the industrial dust contained in the exhaust before the separation of CO2. 3. Because we use amine solvents to collect CO2. 4. The process of separating CO2, preserving CO2, transporting CO2 as well as burying it to the bottom of the ocean is too costly and unreasonable
