Utilizing packed columns for asphalt air blowing
It has been discovered that the efficiency of asphalt blow stills (reactor columns) can be improved by filling the blow still with various types of packing material, such as metal or glass spheres (or other rigid materials). The packing material acts to reduce air bubble size and improve the dispersion of the air bubbles throughout the asphalt. This increases the total surface area per unit volume of the air bubbles and promotes a faster processing time. The packing material also increases the contact time between the air bubbles and the asphalt which further results in improved efficiency and reduced blow times. This is beneficial because faster processing times can be achieved resulting in more efficient use of equipment, higher levels of productivity, lower energy requirements, cost savings, reduced blow loss, and reduced thermal history to which the asphalt is exposed.
