Description
This programme sets out to show how the problems of scaling up a simple brine cell to industrial size are overcome. The four main problems discussed in the previous programme were: 1. The gases p...roduced at the anode and cathode (i.e. chlorine and hydrogen) must be kept apart to avoid the risk of explosive reconbination. 2. The concentration of sodium chloride in the electrolyte must be maintained at a reasonably constant level. 3. The concentration of hydroxide ions must not be allowed to build up - ideally hydroxide should be removed as scon as its formed. 4. The brine cell should be made to operate in a continuous fashion. Dr. Ian Boustead discusses and demonstrates the techniques that have been developed to overcome these problems, and Dr. Gordon Lewis, who managed a large Salt and Chlorine works for many years, describes how these techniques have been put into idustrial practice.
