Dear All,

During shutdown in mid stream (Processing/separation of Water, Salt, Oil and Gas from the crude oil obtained from different field (Well)) ,we found some sludge and some solid particle in three phase separator, electrostatic dehydrator and electrostatic desalter , after that we send these samples for analyzing in which we found following particles.


Quartz (SiO2)
Halite (NaCl)
Anhydrite (CaSO4)
Magnetite (Fe3O4)
Calcite (CaCO3)

Microcline (KAlSi3O8)
Pyrite (FeS2)
Trace metals V, Ni, Fe

Now i have some queries from the above.

1. What should be normal range for the same in crude oil?
2. What is the effect from the above particles in operation/plant?
3. How can we controlled to enter in the plant?

Kindly reply me for the same.

Thanking You,

Regrads,
SS

1. Composition of crude oil varies from region to region. It is difficult to generalize. Some idea about crude oil composition may be obtained from the link below:

http://www.cheresour...n-of-petroleum/

2. High metal content causes poisoning of catalysts in catalytic processes for treatment of crude oil fractions. Materials like silica (Quartz0 will cause fouling and scaling of processing equipment used for crude oil processing in a petroleum refinery. Pyrites can cause fire inside processing equipment due to their property of auto-ignition given the right conditions.

3. There are many processes for solid / sludge removal from crude oil such as filtration, desalting, liquid-solid cyclones, sedimentation etc. Again the choice of method for solids / sludge removal depends on the type of solids / sludge, their qunatity and the economics of processing the crude oil in a given location.

Hope this helps.

Ankur.

Have you any designing information about Slug catchers, three phase separator, electrostatic dehydrator and electrostatic desalter... i mean related to mid stream?

Thanks

sandy38813,

If you use the search feature of the forum you will find a lot of information related to the items you have mentioned. Also google for these items and you should find a lot of information.

Additionally the following books are recommended for upstream / midstream oil & gas:

1. Surface Production Operations - Volume 1 & 2 by Ken Arnold & Maurice Stewart
2. Petroleum Engineering Handbook - Vol. 1 to 7 by Larry W. Lake
3. Petroleum & Gas Field Processing by Abdel-Al, Aggour & Fahim
4. Standard Handbook of Petroleum & Natural Gas Engineering by William C. Lyons
5. Petroleum Engineering Handbook - Society of Petroleum Engineers (SPE) - Editor: Howard B. Bradley
6. Handbook of Offshore Engineering - Vol. 1 & 2 by Subrata Chakrabarti

Hope this helps.

Regards,
Ankur.

hello sir 

 

good day to you. can you please upload the above books or send me the download link if possible.

 

thank you

Hi,

 

In addition to Mr. Ankur comment, these can cause the fouling, scaling (heat exchanger), at upstream level you can reduce the sludge and salt  content. there are many thoughts around this. you can google it.
