Petroleum Engineering Guys, I need a lil help plz...
 

There are some great prizes and gifts that await if I can get some info...

Any of you guys working at an oil refinery? I need some help. I am working on a piece and I need some real world information on the various tests performed on crude coming into the plant as well as the tests run during refining.

Also, if any of you have any text books or the like on Petroleum Engineering, I would love to be able to borrow them for a month or so. I will pay for shipping as well as compensate you with some great prizes and gifts.


I hope you can help me out. Thanks!

I work at a refinery and the information you are asking for could fill a library or three.

Just testing the process stream products keeps about 16 chemists employed full time at this refinery.

I've got lots of books but most are either company property, proprietary, or so egg head and specific they probably won't be of much use.
One sitting on my desk right now is called "applied process design for chemical and petrochemical plants" volume 1.
It tells you how to design and build process units and all the components and I use it all the time, but there are parts that even I can't figure out. It's deep.

I remember reading a long time ago called "petroleum refining for the non-technical person". It's a very good book for general refining theory.

If you could let us know exactly what you are after it could be easier to help.

Agree, I was looking through all the ASTM tests related to crude oil and refining and there are a bunch. Generally speaking viscosity, sulphur and water content would be very important as well as some others. Those are the types of tests I am looking for as well as why they are important.

Specifically I am looking for the tests for the crude oil (the basic ones) as well as the in-prcocess tests run on the distillates primarlilly the bright stock and light oils - the middle distillate range.

Any info on the QC/QA would be fantastic.

You might consider contacting an indepent lab. Try SPL. They have an office in your area probably.

I need an idea of the things that go on at the refinery.

It's all about the hydrocarbons. Broken down to the very basic function - you heat up crude, and you take your product. There are so many processes - hydro cracking, cat cracking, vacuum units, gas oil units, asphalt, sulphur removal...

But at it's core, a refinery turns crude into product - jet fuel, gasoline, kerosene, propane, butane, asphalt etc.

The independent test labs should be able to get into the very details of testing and sampling. They might even be able to hook you up with a local refinery that can offer some help.

Craig, yup, got that covered, what I was needing was the in situ (process) analysis of the material before, during and after for quality control / quality assurance.

Soukus, yup they could but I really need to know is the actual tests run during production for quality control / quality assurance.

There are three basic processes in refining. First is distillation, seperating products by boiling point.
That doesn't "make" anything, it simply seperates and sorts what is already there.
The test for distillation is range and percentage of boiling points of the mixture. Organic chemistry tells us that everything is a mixture.
Nearly all process streams have some sort of distillation.

The second type of process is cracking or reforming.
Using either temperature or catalyst (and sometimes hydrogen) to change the shape or size of the actual molecules. Then it goes to distillation.

Third type of process stream is cleaning.
Removing sulfur, ammonias, water, etc. Usually they use amine products to strip the bad stuff out.
The tests for that is just to see how much of the bad crap is still left.


Here's a little info from a company I worked for a few years ago:

Here's a partial list of the different test procedures they regularly run on duifferent products. Like I said, it could fill a library. Each one of these procedures can be 10 or 20 pages long. If there is a specific test you are interested I can provide some more detail:

BTW when we buy crude oil (we are independent so we don't pull it out of the ground) it comes with an assay report, basically listing all of it's physical characteristics.

We do take samples and test to verify that what we got was what we bought but most of the testing for crude is done long before we ever see it.

This discussion is another reminder of the near-miracle it is that we have readily available fuel from coast to coast for a measly 3 bucks a gallon. Think of the effort and technology that's required from drilling to refining to delivery. It's capitalism at its finest.
