Klappentext zu „Vacuum Technology in the Chemical Industry “
Based on the very successful German edition and a seminar held by the German Engineers` Association (VDI) on a regular basis for years now, this English edition has been thoroughly updated and revised to reflect the latest developments. It supplies in particular the special aspects of vacuum technology, applied vacuum pump types and vacuum engineering in the chemical, pharmaceutical and process industry application-segments. The text includes chapters dedicated to latest European regulations for operating in hazardous zones with vacuum systems, methods for process pressure control and regulation and leak detection.All of the authors work or did work at a selection of the most important German companies involved in vacuum technology, and their expertise is disseminated here for engineers working in vacuum technology, chemical process design, plant operation, and mechanical engineering.

Autoren-Porträt
Wolfgang Jorisch studied chemistry at RWTH in Aachen, Germany, and received his degree of Dr. rer. nat. for technical chemistry from the University of Essen. From 1987 to 2000 he was a member of the technical chemistry department of the RWTÜV in Essen and manager for chemical applications at Leybold Vacuum in Cologne, Germany. From 2000 to 2005 he was a member of the US/ UK-Graham Vacuum Technology group and since 2005 he holds the position of manager of the German IVPT (Industrielle Vakuumprozeßtechnik) on site of Leybold in Cologne.He acted as editor of the German version of the book Vacuum Technology for the Chemical Industry and has been managing the VDI-seminar with the same title for several years.
