Book excerpt: Explosion hazards involving mixtures of different states of aggregation continue to occur in facilities where dusts, gases or solvents are handled or processed. In order to prevent or mitigate the risk associated with these mixtures, more knowledge of the explosion behavior of hybrid mixtures is required. The aim of this study is to undertake an extensive investigation on the explosion phenomenon of hybrid mixtures to obtain insight into the driving mechanisms and the explosion features affecting the course of hybrid mixture explosions. This was accomplished by performing an extensive experimental and theoretical investigation on the various explosion parameters such as: minimum ignition temperature, minimum ignition energy, limiting oxygen concentration, lower explosion limits and explosion severity. Mixtures of twenty combustible dusts ranging from food substances, metals, plastics, natural products, fuels and artificial materials; three gases; and six solvents were used to carry out this study. Three different standard equipments: the 20-liter sphere (for testing lower explosion limits, limiting oxygen concentration and explosion severity), the modified Hartmann apparatus (for testing minimum ignition energy) and the modified Godbert–Greenwald (GG) furnace (for testing minimum ignition temperature) were used. The test protocols were in accordance with the European standard procedures for dust testing for each parameter. However, modifications were made on each equipment in order to test the explosion properties of gases, solvents, and hybrid mixtures. The experimental results demonstrated a significant decrease of the minimum ignition temperature, minimum ignition energy and limiting oxygen concentration of gas or solvent and increase in the likelihood of explosion when a small amount of dust, which was either below the minimum explosion concentration or not ignitable by itself, was mixed with gas or solvent and vice versa. For example, methane with minimum ignition temperature of 600 °C decreased to 530 °C when 30 g/m3 of toner dust, which is 50 % below its minimum explosible concentration was, added. A similar explosion behavior was observed for minimum ignition energy and limiting oxygen concentration. Furthermore, it was generally observed that the addition of a non-explosible concentration of flammable gas or spray to a dust-air mixture increases the maximum explosion pressure to some extent and significantly increases the maximum rate of pressure rise of the dust mixture, even though the added concentrations of gases or vapor are below its lower explosion limit. Finally, it could be said that, one cannot rely on the explosion properties of a single substance to ensure full protection of an equipment or a process if substances with different states of aggregate are present.

Available in PDF, EPUB and Kindle. Book excerpt: Damaging accidental explosions are a continuous threat to industry. Categories for such explosions include combustible dust explosions; reactive gas explosions, both confined and unconfined; hybrid explosions involving both gases and dusts; bursts of pressure vessels and piping; and liquid propellant explosions. This book evaluates the physical processes and resulting blast effects for these types of explosions. Special attention is given to reactive gas explosions, both confined and unconfined. This latter class of explosion has occurred all too frequently in refineries and petrochemical complexes, and is also one of the most difficult to predict and evaluate. Much recent work on this topic is reviewed and summarized. This is the only publication of its kind, to date, that offers such a thorough coverage of these types of industrial explosions. [p] Each class of explosion source is reviewed separately, first discussing fundamentals, then presenting methods of analysis and testing, and finally giving curves or equations to predict effects of the particular class of explosion. An extensive bibliography is included together with tables of pertinent properties of explosive materials. The text also includes many figures, equations, tables and a keyword index. The book is intended for researchers in the field of characterizing and mitigating industrial explosions. It will also be of interest to engineers, scientists, and insurers involved in processes.

This book was released on 2016-06-14 with total page 576 pages. Available in PDF, EPUB and Kindle. Book excerpt: Explosion Hazards in the Process Industries, Second Edition, delivers the most current and comprehensive content for today’s process engineer. Process safety and petrochemical engineers inherently accept that there is a risk of explosions when working on process facilities such as plants and refineries. Yet many that enter this field do not have a fundamental starting point to understand the nature of explosions, and there are a lot of misconceptions and impartial information in the market. Explosion Hazards in the Process Industries, Second Edition, answers this need by providing engineers and consultants a go-to reference and training guide to understand the principles of explosions, what causes them, and how to mitigate and prevent them from reoccurring. Enhanced to include new chapters on BLEVE (Boiling Liquid Expanding Vapor Explosions), water vapor explosions, and destructive effects from accidental explosions, this guide continues to fulfill a comprehensive introduction to the subject, rounded out with new case studies, references, and a discussion on methods of hazard and risk analysis. Offers a comprehensive introduction to process safety Includes updated new chapters on Boiling Liquid Expanding Vapor Explosions (BLEVE), water vapor explosions, and destructive effects for accidental explosions Gains new case studies, references, and standards to stay on top of what is new and critical Establishes the starting point to process safety and understanding the fundamentals of explosions and how to mitigate them

Book excerpt: The author summarizes todays knowledge of the cause and consequences of dust explosions which were the main focus of his professional life. The presence of explosible dust/air mixtures does not generally represent a risk of an explosion although all organic and metallic dusts are explosible. The author develops test-methods for explosion hazards associated with dust and constructive methods to prevent dust explosions. The book is written for practical use. The reader learns to recognise the hazard of a dust explosion and the effectiveness of safety measures. The book is richly illustrated and demonstrates the correct use of the empirical theories.
