Refinery Inspection Properties - Part 3
Some acronyms which are related to RVP.
RVP- Ried Vapor Pressure.
TVP-True Vapor Pressure.
ASTM methods(Wet,Dry)- Defined propcedure to calculate RVP.
Very important property where petroleum industries regularly update the values based on seasons as it is a measure of absolute vapor pressure.
In winter season - Need higher values of vapor pressure as it may clog because of condensation will happen.
In Summer - in similar way to avoid vapor lock in summer season RVP values are in lower levels.
This is a labaroary method which is tested in a bomb like structure containing two chambers. in one chamber sample to be tested is used in another propably air the ratio is 1:5 , 1 part of sample and 5 parts of air.
How to relate with simulation(1:5 parts of sample(1 atm) and air(vacuum)), laydown two sources one containing sample and another containing air. mix the two streams from source 1 and source2 using mixer(m1) and try to calculate the out put stream(s3) properties.
Try different options on slecting different sources other than air and sample and see how out put s3 is varying.
In lab source1 might be in one chamber and source2 in another.
Reid vapor pressure is always measured in Psi and it is less than TVP(True vapor pressure).
Note: This is just written based on my experience in simulation field.
