International Working Group on Process and Plant Safety
Who is EDUG ?
If you have found your way this far then you may already know a little about EDUG and DIERS, and its work on emergency relief system design. But in case you don’t here is some brief information about who the EDUG group is, what EDUG do and how to join EDUG. Sources of further information and the member organisations of EDUG are given below.
EDUG is the European DIERS Users’ Group and the word DIERS stands for The Design Institute for Emergency Relief systems. In other words, EDUG is a working group of (mainly) Europeans who work on emergency relief system design using technology developed by DIERS. Members also carry out research in this field and are often involved in developing guidance and standards.
The member of EDUG are industrialists, consultants and academics who are working in the field of process and plant safety in their day to day professional lives: it is, if you like, a self-help group of people who get together once a year to discuss safety related activities, applications and problems that may be of mutual interest. Some of the member also do research into developing the technology further or are involved in developing European standards and regular updates are given. We take it in turns to host the meetings in our normal places of work and try to keep the cost of what we do as low as possible.
Background/ About EDUG
DIERS was a consortium of (mainly chemical) companies and organisations originally set up in the USA in 1976, under the auspices of the American Institute of Chemical Engineers (AIChE). Its purpose was to develop the technology and methods needed for designing emergency pressure relief systems for chemical reactors, particularly those in which exothermic reactions are carried out. Such reactions include many classes of industrially important processes including polymerizations, nitrations, diazotizations, sulphonations, epoxidations, aminations, esterifications, neutralizations and many others. Pressure relief systems can be difficult to design, not least because, just as with a can of carbonated drink when it is suddenly opened, what is expelled can be gas/vapour, liquid, or a mixture of the two. For chemical reactions, it requires extensive knowledge of both chemical reaction hazards and fluid flow.

Would you like to join us?
If you want to join in our activities then EDUG welcomes new participants who also work in this area – but we do expect you to become actively involved. Our meetings are friendly but technical in nature and the EDUG forum would not be appropriate for presentations of a purely commercial or sales content.
If you have questions or want to join the group, please leave a message to:
