Development of Energy Efficiency at Mass Transfer Rates in Electrochemical Cells.

What is it about?

Augmentation is a well adopted strategy for any process industry to be competitive. Augmentation of transfer process offers lower equipment size for a given capacity (or) sometimes better quality of product. Electro-chemical cells assimilated several techniques for the augmentation. Intense turbulence generation is one among several techniques. The turbulence can be generated by several means. The present study is envisaged to obtain a higher augmentation by adaptation of entry region vanes to generate swirl in homogeneous flow.

Why is it important?

The effort is made to acquire higher augmentation rate with lower frictional losses and high efficiencies. It may lead to the construction of energy efficient transfer operation. In these operations , electrochemical reaction takes place at the electrode surface where the reaction rates, are fast and mass transfer is diffusion controlled. Considerable research activity is undertaken to enhance the transfer rates in electrolyte cells. Higher mass transfer rates can be achieved by resorting to the flow of the electrolyte at higher velocities. The present mass transfer study is undertaken to investigate the effect of entry region vane promoter in homogeneous flow. An electrochemical technique using a diffusion-controlled electrode reaction was employed to determine the ionic mass transfer rates through limiting current technique.
