Design a staggered depressurization sequence for flare systems
Emergency depressurization is one of the most important design provisions for safeguarding facilities in case of an emergency. To overcome limitations of flare system capacity during such a scenario, depressurization can be practiced in a sequential manner. Presented here are the criteria and calculation methods for designing sequential depressurization, along with guidelines for the implementation of recommended designs.
Rethink the hazards in your process
In designing process safety systems, “more” is not necessarily better. Advanced technology has created a mindset to over-install hardware to prevent or to reduce the risk of failure in hydro..
Consider process-based failure analysis methods for piping and equipment
Avoiding incident (or accident) recurrences at industrial systems is a long-standing problem, and it involves process safety strategies (PSSs). Incurring zero incidents is the ultimate goal for any st..
