Explosion vent, information

The first alternatives are well docmnented in the relevant technical regulations. Detailed information on the design of dust explosion relief systems can be found in the German VDI-3673, the British guide on dust explosion venting HSE 1977 and the US standard NFPA 68. 

Sources of information about the isotopic composition of the upper portion of the lithospheric mantle come from the direct analysis of unaltered ultramafic xenoliths brought rapidly to the surface in explosive volcanic vents. Due to rapid transport, these peridotite nodules are in many cases chemically fresh and considered by most... 

Since the first edition of this book appeared in 2003, the field of solvent-free organic synthesis has undergone an explosion in research and I have received considerable response from readers. With the aid of this information I have completely updated this book. In this second edition, over 200 examples of new sol-vent-free organic reactions, published in the journals during 2003 to 2007, have been added. The most obvious changes in this book are the two new chapters one on polymerization (Chapter 14) and the other on supramolecular complexa-tion (Chapter 15). Additionally, all the sections on solvent-free reactions under microwave irradiation have been deleted, since Professor A. Loupy covers this area in his book on Microwaves in Organic Synthesis (Wiley-VCH, 2006). 

Tanks should either be of frangible roof construction, or should be equipped with an emergency vent of adequate area to prevent over-pressure under accidental relief conditions, which exclude internal explosions. For further information reference should be made to EEMUA...
