ARCHIVE -- this event already took place.
Safety and the prevention of incidents are important aspects during the design and operation of chemical facilities. Apart from the legal obligations to reduce the chances and effects of incidents, there is an economic drive to maximize safety. Direct damage of process equipment may result in the loss of market share and a detoriation of corporate image. A first line of defence is to prevent accidents from happening. However, first line safety measures may fail and a second line of defence should be in place. This is especially the case when an increase in pressure may result in rupture of equipment with a subsequent release of hazardous materials. Emergency relief systems are very suitable in forming this second line of defence. Not only will a relief system prevent the excessive pressure, it will also prevent toxic and/or flammable chemicals from entering the environment.
Designing a proper system for gas, vapour, liquid or solid relief is usually performed by specialists. However with the knowledge of this course you will be able to guide and check the process of designing a relief system.
During this day our safety experts will present a mix of exercises, demonstrations and lectures. The lectures will give you the practical and theoretical background of relief systems. The laboratory demonstrations will let you experience the forces and effects that occur during a real emergency relief. Both are needed to get grip on how to design a proper emergency relief system.
Akzo Nobel Safety Services is the primary safety research institute
of Akzo Nobel since the early 1960’s. We have many years of experience with the design of emergency relief systems. This course is a compilation of these years of experience.
Objectives
Providing know-how on:
• practical theories behind relief systems and relief equipment
• the ability to make “quick and not too dirty” calculations necessary for the design of relief valves, rupture disks, piping and containment equipment
• understanding the need for venting systems through various demonstrations
• important experimental and computational techniques for determining the vent size
Who should attend
Plant engineers, process engineers, HSE officers, design engineers, and everybody else who on account of his/her function in the fields of R&D, design or production may be faced with emergency relief issues.
Main subjects
* Introduction into gas, vapour, liquid and solid relief systems
An overview is given of the different possibilities to relieve materials from process equipment.
*Simple calculation methodes for determining relief diameters
This section will deal with simple calculations schemes to determine the pressure drop and the minimum relief area.
* Experimental techniques necessary for relief sizing
If certain physical, chemical or reactive properties are unknown, calculations will fail. In those cases experiments have to be performed. During this section experimental techniques are described and shown.
* Containment systems
It is important to release materials to a safe location. This part of the course will deal with the design of flares, cyclones, knock-down drums and piping.
* Gas and dust explosion venting
Gas and dust explosions are a special part of this course and need different calculation and testing methods.
