Dear community,

 

We are operating a crude oil treatment plant and  want to quantify the gain in the production by increasing the RVP of the produced crude oil which is then stored in floating roof tanks of 50000 m3 capacity each one. I looking for a correlation in order to estimate the gain in the production. Your help is very appreciated.

Hi,

Please explain more your purpose.

HI MAHDI,

 

Thank you for the reply.My purpose is to estimate the increase in the production in case we increase the reid vapor pressure of the produced crude oil let's say from 0.55 bar to 0.75 bar. I think it's clear now

How does your overall process flow look like? Is it similar to the one below?

 

 

If yes, is this going to be achieved by lowering the temperature at the Crude Heater before going to oil dehydration?

 

I assume this is fairly easily done with a simple simulator? Get a TBP curve of your crude, and get a sample of the light gases at the Oil dehydration outlet and combine it at the feed. Using different temperatures of the crude heater outlet, you get different vapor pressures and thus different crude yields..

Colt16,

I don't see the process flow you have mentioned. Any way, in our plant the RVP control is achieved only by adjusting the bottom température of the stabiliser colomn.

In that case, with a simple simulator, you can combine the overhead and the bottoms, to regain the composition of the feed.Then simulate the Stabilizer and run it at different bottom temperatures and you will see the extra production.
