En días hábiles, la actividad vehicular más intensa en calles y avenidas de la ciudad de México se inicia a las 6:00 hs y se prolonga por aproximadamente 3 ó 4 horas. En ese periodo, la capa de mezclado permanece relativamente quieta y expuesta a recibir una carga importante de contaminantes producto de emisiones vehiculares. En esas condiciones de ausencia de movimientos atmosféricos verticales y horizontales, y de intensa actividad contaminante, adquieren importancia los procesos de dispersión que ocurren en la horizontal y a nivel del suelo.
En este trabajo se lleva a cabo un proceso de promediado de las …

Study On The Activity Of New Amine Based Absorbents For Co2 Absorption From Flue Gases, João F. Gomes
Study On The Activity Of New Amine Based Absorbents For Co2 Absorption From Flue Gases, João F. Gomes
João F Gomes
The capture of CO2 from flue gases can be done by chemical absorption with aqueous amine solutions like MEA (monoethanolamine). Although this is a proven process, there are still operational problems to overcome [1], namely those resulting from solvent degradation, precipitation, corrosion and foaming. Also, the absorption capacity of the most current amines must be improved in order to obtain a more profitable operation. It has been shown previously that relationships exist between the amine structure and the activity/capacity for CO2 absorption. The introduction of amine substituents at the α-carbon creates a carbamate instability, which causes the hydrolysis to go …
