Safe Design

Safe design of processes must consider the full spectrum of design and risk management opportunities ranging from reducing potential consequences via Inherently Safer Design (ISD) to reducing risk through process and job design. Since ISD can be robust and reliable, it is a good place to start. Also, check out this article on Remote Isolation and Shut Off

Inherently Safer Reactor Design for Complex Reactions Based On Calorimetry Studies

Mar 13, 2011
Alba Lucia Pineda
A number of reactive processes of the agrochemical, fine-chemicals and pharmaceutical industries involve thermally unstable and/or toxic reactants, products or intermediates, for which the chemistry, thermochemistry and thermodynamic properties are barely known. They frequently employ multipurpose...

Improvement of BLEVE Overpressure Method Using Historical Data

Mar 13, 2011
Fei Chen
The current CCPS/TNO's BLEVE (Boiling Liquid Expanding Vapor Explosion) overpressure methodology is derived from that published by Baker in 1975. This methodology assumes isentropic expansion work and uses Baker's graphical method and high-explosive correlation to calculate BLVE energy and...

On the Potential of Mitigating Vapour Cloud Explosions Using Flame Inhibitors

Mar 13, 2011
Kees Van Wingerden
Very few measures are taken to mitigate the possible consequences of vapour cloud explosions. The main attention is given to prediction of the consequences, which is used to consider strengthening structurally or re-locate occupied buildings such as control rooms. However little is undertaken to...

Kinetic Modeling of the Reactions Involved in the T2 Explosion

Mar 13, 2011
Ronald J. Willey
The runaway reaction at the chemical preparation facility called T2 laboratories in Jacksonville, Florida on December 19, 2007 is analyzed. The approached involved estimating kinetic parameters based on temperature time traces presented in the CSB final report for ARSST (Advance Reactive System...

Guidelines for Process Safety in Bioprocess Manufacturing Facilities

November, 2010
This book helps advance process safety in a key area of interest. Currently, no literature exists which is solely dedicated to process safety for the bioprocessing industry. There are texts, guidelines, and standards on biosafety at the laboratory level and for industrial hygiene, but no guidelines...

Condensation Induced Water Hammer: Principles and Consequences

Mar 23, 2010
Carlos A. Barrera
An explosion occurred in the boiler room of a food processing plant as the steam generation system was coming online after a maintenance shutdown. The explosion shattered the case of the condensate return pump fatally injuring an employee, while another employee was burned by the escaping steam...

High Integrity Protective System Design Using a Risk Based Approach

Mar 22, 2010
Robert J. Stack
With the update of the High Integrity Protective System (HIPS) methodology by API in 2007, Dow Chemical updated its internal work process to apply Dow's risk based work processes to HIPS design, application and evaluation. Rather than just focusing on the vessel related consequences of substituting...

Dust or Gas Explosion: Case Study of Dryer Explosion and Design Venting

Mar 21, 2010
Scott Davis
A recent explosion occurred in a single burner, recirculating solids ring dryer. No one was reported injured as a result of the explosion, however the explosion caused significant damage to the dryer and minor damage to sections of the facility. Despite the dryer having been designed with seven...

HAZOP, LOPA, SIL: Be Careful What You Ask for!

Mar 21, 2010
Mike Broadribb
In recent years Process Safety Engineers have promoted the use of HAZOP to identify hazards and assess safeguards, followed by LOPA to identify if additional protection layers are necessary and, if they are to be provided using safety instrumented functions, how reliable the SIFs need to be...

Food and Consumer Products Process Hazards

Apr 28, 2009
Catherine Kollhoff, Guy Colonna, John Bresland
The Food and Consumer Products area has significant hazards and risks from dust and flammable liquid explosions as well as from toxic releases. Moreover, the Montreal Protocol for the removal of Ozone Depleting incudes papers on the identification, prevention, control, and management of hazards and...

Fires, Explosions and Reactive Chemicals

Apr 27, 2009
James VanOmmeren, Lina R. Saenz
The analysis, prevention, protection and mitigation of fire, explosion, and reactivity hazards continue to be important to the loss prevention community. This session contains papers that identify, characterize, or offer design and operational guidance on fire, explosion and reactivity hazards...

Guidelines for the Management of Change for Process Safety

March, 2008
Guidelines for the Management of Change for Process Safety provides guidance on the implementation of effective and efficient Management of Change (MOC) procedures, which can be applied to improve process safety. In addition to introducing MOC systems, the book describes how to design an initial...

Guidelines for Mechanical Integrity Systems

July, 2006
In recent years, process safety management system compliance audits have revealed that organizations often have significant opportunities for improving their Mechanical Integrity programs. As part of the Center for Chemical Process Safety's Guidelines series, Guidelines for Mechanical Integrity...
