Screening for PRV Stability – Inlet Pressure Drop and the 3 Percent Rule
Chatter is most likely in vapor service, damage will most likely be due to large mechanical forces caused by the rapid valve closure and/or by PRV reduced flow capacity due to PRV damage.
Screening Tool for Runaway Reaction Characterization Optimizing Efforts for ERS Design Poster
Adequate Emergency Relief Systems (ERS) design can ensure the safety and integrity of the system. However, not all desired chemical reactions or unstable mixtures present the same level of risk, and accordingly, not all of them require the same level of effort and time for ERS design.
Sizing Relief Systems for High Viscosity Two-Phase Flow
Qualify your design methods for high-viscosity two-phase relief systems against these simple benchmarks. High viscosity two-phase (HVTP) flow occurs in many industrial scale reactors, particularly when runaway reactions (e.g., during polymerizations) are vented through an emergency relief system.
The Oxygen Balance for Thermal Hazards Assessment
It is a matter of considerable practical importance to recognize metastable, potentially hazardous chemical compositions so that suitable thermal hazard management means can be provided as a part of process safety management.
Thermo Kinetic Analysis Reactions Involved in the Manufacture of o-Nitroaniline
Exothermic reaction processing must be concerned with potential consequences when heat released by the reaction exceeds that removed by the reactor coolant system, a situation known commonly as a runaway reaction.
Unconfined Vapor Cloud Explosions: A New Perspective
A modern perspective on the problem of vapor cloud and explosions is given. Particular emphasis is placed on the important practical problem of detonation hazards.
The fundamental heat transfer equation outlined in API Standard 521, Pressure-Relieving and Depressurizing Systems, is the basis for the wall dynamics approach. This presentation shows the advantages and characteristics of the wall segmentation approach implemented in Process Safety Office® SuperChems™.
What Comes to Mind When I Think About Process Safety
Once you get into process safety, you realize that it is really a way of life. You also realize that you have become a disciple of the “Power of Negative Thinking” mantra. We are always trying to prevent bad things from happening and to learn from incidents. It is not always about negative thinking though; in process safety we convert failures into lessons learned and future successes. That is why AIChE through CCPS, the Safety and Health Division, and DIERS, has made and continues to make the world a better and safer place.
