|Hi, please explain for me why mercaptans almost absent in crude oil. I think that crude oil contains rarely olefins. Because gas, naphtha, and kerosene which straight-run from crude distillation tower always be treated mercaptans.|

|Agree with you. It should be olefins because olefins are very easy to transform to oxidation compounds.|
|Chinna said: (Nov 11, 2014)|
|Yes you both guys are right and olefins are form in refinery process only it means olefins are absent in crude oil.|
|Manikannan said: (Nov 27, 2014)|
|Ya correct Olefins are formed during cracking only.|
|Ajay said: (Jan 15, 2016)|
I am agreed from both of you, the correct answer is Olefins.

|Mercaptans are found especially as impurity in crude oil distillation, so why mercaptans absent?|
|Aba Oryina said: (Jun 29, 2016)|
|Yeah, I also think it's olefins.|
|Aditya Sharma said: (Jul 24, 2016)|
|I think it should be Olefins.|
|Aniket said: (Sep 27, 2016)|
|I also agree the answer is option A.|
|Tenendra Patle said: (Oct 4, 2016)|
|Yes, I also agree because olefins are intermitted product during cracking process.|
|Golu said: (Jan 16, 2017)|
|Yes, I agree to all of you, olefins are intermitted product.|

|Olefins is the right answer.|
|Shivam Singh said: (Sep 6, 2017)|
|Olefins is the true answer.|

|Mercaptan is correct as olefin which seems to be the correct answer is absent and not almost absent.
Mercaptans which have on average 1-3% wt fraction of petroleum.
From the given option, Mercaptan is the right answer.

|I think, the correct answer is Olefin.|

|Olefin is the right answer.|

|We know that alkenes are mostly not present in crude petroleum. And olefin is a type of alkene. So the right answer is A, not B.|

|I don't think Olefin will be the right answer. In NHDT (Naptha Hydrotreater) diolefins are converted to olefins 1st and then olefins are transformed into straight-chain paraffin. It is then going to Isomerisation process. So, there are a lot of olefins in crude and it produces gum also.|
