Pressure Relief
This type of pressure relief device should be used in corrosive surface.
What is a rupture disk?
This is why methane is preferred over hydrogen as a fuel from a safety standpoint, based on their flammability ranges.
What is methane has a narrower flammability range compared to hydrogen.
This type of reactive chemical hazard self-ignites without needing an ignition source, and examples include iron sponge and alkali metals.
What is a pyrophoric material?
This industrial sector uses the smallest ΔTmin values of 3-5°C because refrigeration costs are extremely expensive.
What are low temperature processes?
This scientist is credited with the discovery of penicillin.
Who is Alexander Fleming?
For a single relief valve scenario (non-fire), the maximum set pressure is equal to this.
What is the MAWP?
According to Marsh Research, this event type accounted for 15 out of the 20 largest losses in the hydrocarbon industry.
What are explosions?
This is the one reactive chemical hazard category that the SDS does NOT easily help you identify.
What is incompatibility?
This is what the slope of a stream on a T vs. ΔH plot represents.
What is 1/CP (the inverse of the heat capacity flow rate)?
The quote "The dude abides" is from this movie.
What is The Big Lebowski?
For a single relief scenario (non-fire), the overpressure can be up to this amount.
What is 1.1*MAWP?
This is the lowest temperature at which a liquid gives off enough vapor to form an ignitable mixture with air, lasting only a short duration.
What is the flash point temperature?
This is the physical condition that a calorimeter replicates by insulating the test vessel, preventing heat exchange with the surroundings.
What are adiabatic conditions?
When ΔTmin decreases, this happens to capital cost and energy cost respectively.
What is the capital cost increases and energy cost decreases?
This famous Youtuber started his career as a plumber in the UK prior to making it big on YouTube.
Who is Colin Furze?
If a PRV with a set pressure equal to 300 psia relieves into a flare header with a terminal pressure equal to 25 psia, this is the pressure at the discharge of the PRV.
What is 55 psia?
In a detonation, unlike a deflagration, the flame speed has this relationship to the speed of sound, causing the reaction front and shock front to travel together.
What is faster than (greater than) the speed of sound?
Even though no heat is released, endothermic reactions can still pose a reactive chemical hazard due to the generation of these.
What are gases?
Above the pinch, this is the required relationship between the number of hot streams and cold streams for a feasible heat exchanger network.
What is the number of hot streams must be less than or equal to the number of cold streams.
This surfer in the movie Surf's Up is credited with saying "Trust your nuggets."
Who is Chicken Joe?
What are always preceded by a knock-out drum and liquid seal drum.
What are flares?
This is the only thing standing between the maximum theoretical explosion energy and the TNT equivalent mass you actually use in your damage calculations.
What is the explosion efficiency (η)?
This is what the dimensionless parameter B physically represents.
What is the dimensionless adiabatic temperature increase.
This is why oil refining requires a ΔTmin of 20-40°C compared to petrochemicals which only need 10-20°C.
What is higher fouling of heat exchangers?
In this 1993 film, a mathematician warns that a theme park's chaotic system cannot be controlled, a lesson every chemical engineer learns about runaway reactions and loss of process control.
What is Jurassic Park?
