Dear All,
Tried to search in the forum about the topic but couldn't get anything hence posting.
Our laboratory want to measure RVP of the Crude Oil. They are doing open sampling from the pipeline in the field and sample is exposed to atmosphere while sampling. Means whatever gases are there in oil are gone off while sampling. The container in which they are taking sample is chilled one with ice and chilled water around. They are also using a cooling coil in bucket to cool the sample before coming to sampling container.
My understanding is that the sample shall be taken in close environment and it should not be exposed to atm. or else all gases will be vented and the RVP reading will not be the correct one. After all they (gases) only will be contributing for RVP reported at 37.8 °C.
I just want to know that while taking sample for RVP measurement exposing it to atmosphere is okay? Will it still give correct RVP?
Request you all to throw light on this.
Goga.
