This book is based on the course notes from the introductory process control class at Strathclyde University in Glasgow, Scotland. This course is itself based on the IChemE model-curriculum for chemical engineers and covers the material that ALL chemical engineers are supposed know. The IChemE curriculum was drawn up by a team of industrialists and academics, led by Professor Jon Love, in response to a recognized need for chemical engineers to be taught a more industrially relevant course. This book isn’t a traditional academic textbook in that there are no references anywhere in the text.

The main reason for this is that the material has been gathered from many different sources after a working lifetime of teaching in the area and trying to identify an original source is impossible. I have included a bibliography for readers who wish to look further into the subject.
