INSTRUMENTATION AND AUTOMATION IN PLANTS OF THE CHEMICAL AND OIL INDUSTRY
In a comprehensive survey of recent developments in the field of instrumentation and automation in the chemical and petroleum industry, radioisotopes are mentioned with respect to measurements by means of nuclear radiation, especially gamma rays. Here practical and economical solutions for difficult measurement problems have been devised and are already applied to (a) level gaging, (b) density measurements, (c) observation of chemical reactions, and (d) measurement of wear of apparatus and of their corrosion. All these measurements can be used with electronic relays for automation and control. Radioisotopes are applied in the food industry for processing fruit juices, in the evaporation and concentration of milk, the manufacture of chocolate, etc., and for nondestructive testing of chemical machinery and instruments which are exposed to great siress due to high temperature and the corrosive nature of many chemical substances and reactions. By using x rays or gamma rays, the effects of these factors can be followed during chemical operations, and the nature of corrosive destruction can be determined qualitatively and quantitatively.
