    The increasing use of fossil fuels for energy generation and the high emission of greenhouse gases associated with these processes have made it necessary to develop technologies that can mitigate their impact. The chemical absorption process of CO2 using aqueous amines has been implemented in the industry for several decades and is considered a viable strategy for medium-term CO2 emissions mitigation. Pumping highly viscous fluids such as amines requires large amounts of energy, and they are commonly mixed with water to improve their fluidity. This mixture negatively impacts reaction rates, resulting in the need for larger equipment to capture the same amounts of CO2. Additionally, the regeneration process of aqueous amines requires the supply of large amounts of energy to increase their temperature and release the CO2. These kinetic and energetic characteristics of the process are the main obstacles to the widespread implementation and extensive use of this technology in the industry. This work continues the construction process of a plant for chemical absorption using aqueous amines. It builds upon the construction of a gas capture plant that took place in 2018, aiming to operate in a steady state and monitor the performance of different types of amines, amine mixtures, and operational conditions of the system in order to find alternatives that can reduce the energy cost of the process.
