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...

Safe Design and Operation of Process Vents and Emission Control Systems

March, 2006
Process vent header collection systems are subject to continually varying compositions and flow rates and thus present significant challenges for safe design. Due to increasingly demanding safety, health, environmental, and property protection requirements, today's industrial designers are faced...

RELEASE: A Model with Data to Predict Aerosol Rainout in Accidental Releases

March, 1998
This book documents CCPS's Aerosol Research Program to develop a model to predict liquid rainout from release of a pressurized, liquefied gas--and, hence the residual amount of material in a vapor cloud, which may be greater than the amount calculated from an enthalpy chart. RELEASE predicts the...
