1.   Chemical engineering companies found that their very large complex expensive process plants could be controlled better by computer than by human operators.

2.   The most difficult phase was the analysis of cognitive processes in fault-finding in such a highly complex process plant.

3.   The demand for higher production levels leads to more formal manufacturing methods and some special process plant is justified.

4.   The process plant is special purpose, automatic and specific to products.

5.   It is very hard for regulations to cover the interactions of complete systems in complex process plants, for example.

6.   A further aspect of overtaxation arises from differences in valuation for industrial use of process plant.

7.   An engineering working party is looking at all aspects of converting or replacing CFC refrigeration equipment at ICI process plants across the globe.

8.   Mark Shotwell, a manufacturing supervisor at the process assembly plant, shows the bins where his team is doing this.
