Mixing and Blending

Pulsair Systems and Linde Gases have partnered to provide a more effective and efficient way to mix liquids. Pulsair’s pulsed-air technology releases compressed air or gas, supplied by Linde, from beneath flat round plates at the bottom of a tank or vessel to create circulation and effect mixing of the liquid(s). As the gas is forced out between the plates and the tank floor, the sudden burst shocks the liquid and sweeps away the heavier liquid(s) and solids. The gas accumulates above the plate into a single large, oval-shaped bubble that rises to the surface, creating a vacuum that pulls heavier liquids and solids up from the bottom of the vessel and pushes the lighter liquid up and out toward the tank perimeter. The lighter liquid moves to the sides of the tank and travels down the tank walls to the bottom so the process can be repeated. The use of pulsed compressed air ensures complete and even blending of different-density materials. The technology significantly reduces operational costs and downtime — with no moving parts inside the tank, the mixers require minimal maintenance and can be expected to complete 100 million blending cycles without incident. Pulsair Systems, www.pulsair.com and Linde Group, www.linde.com
