The programme looks at the industrial conversion of ethylene and chlorine to vinyl chloride. The BP plant at Baglan Bay is used as an example.

|Ian Boustead introduces the programme. He points out three methods by which the vinyl chloride production process can be described. Boustead uses a model of the Baglan Bay plant to briefly describe the production process. This is related to a flow diagram using animation. Film shots of the Baglan Bay plant. Commentary by Boustead explains how the process works. Close-up shots of various parts of the plant as he talks. Diagrams of the process intersperse the film. Film shots of the fractionation columns. Commentary by Boustead describes the oxychlorination process which produces DCE. Diagrams intersperse the film. Boustead discusses problems of ensuring efficiency in handling materials during the process. Using a flow diagram, he explains how different sub-processes are combined to give good economies. Boustead next discusses problems of ensuring efficient use of energy in the process. He concentrates on the separation of HC1 from the cracked gas products as an example. Boustead tries to design a plant working at atmospheric pressure and points out its drawbacks. Several process diagrams, some animated, are used as visual aids. Boustead explains how these problems could be overcome by a system working at high pressure. (14atm). More animated diagrams are used.
