ABSTRACT

A static mixer is a device inserted into a pipeline with the objective of handling liquid streams to divide, recombine, accelerate, spread, swirl or form layers as they pass through the static element. Most fluid processing industries such as Chemical, Oil, Gas and Petrochemical Industries use static mixers with an extensive range of applications. Static mixer integrated with different static elements in a tubular arrangement enables the flow of fluids in various directions, and it catches more importance in terms of less energy depletion and more mixing rate. Static mixing with perforated baffle elements is used to improve fluid mixing with minimal energy consumption as compared with dynamic mixing. Pressure drop, Consumption of energy, Bubble size and Rate of mass transfer are mainly taken into account to test and design the static mixer element for air-water and air-kerosene system. Here we tested different baffle type elements to observe and compare the above mentioned hydrodynamic properties. This investigation shows that perforated baffles show better result in terms of improved mixing performance, higher mass transfer rate and minimal power consumption than other static elements in the existing works of literature.
