Frequency of diesel flash point analysis
Thread Content
I would like to ask my colleagues to discuss: how often should the flash point of hydrogenated refined diesel be tested and analyzed?
Considering the frequency of diesel sampling and analysis for this device, the flash point needs to be analyzed after each sample collection; 4 to 6 times per day is a common frequency.
Refined diesel – Density: Method for determining the density of petroleum and liquid petroleum products (density meter method), GB/T1884-2000; 1 time per 24 hours. Boiling range: Method for determining the distillation characteristics of petroleum products, GB/T6536-1997; 1 time per 8 hours. Freezing point: Method for determining the freezing point of petroleum products (GB/T510-1983); 1 time per 24 hours. Flash point: Method for determining the flash point of petroleum products (closed cup method), GB/T261-1983(1991); 1 time per 4 hours
As long as the processing volume and the process parameters of the entire tower remain stable, one operation per shift is sufficient. Production fluctuations can be compensated by adding samples.
We also analyze it once per shift!
It depends on the regulations set by the workshop; since our products are evaluated based on the flash point of diesel, the testing frequency for the flash point of our diesel is once per shift! !
During normal production, it is done once per shift; when production is unstable, it depends on the extent of fluctuations in the operating parameters
Based on production needs, if the raw materials do not change frequently, once every 4 hours is sufficient
We analyze it here every 4 hours.
We do it every 4 hours; in the event of an accident, additional samples are taken depending on the adjustments needed. Generally, the flash point is relatively easy to adjust.
Once a day is sufficient, up to twice at most； Two times a day is sufficient when adjusting the raw materials.
Take over once, hand over once. . . Over and over again. . .
We do it twice a day now; the final quality check of the oil products takes place before they leave the factory
