Gas Oil Caustic Treating Feasibility

[TKetele]

We planning to sell our LVGO on the local automotive market as premium Diesel. Our main property problem is our high Total Acid Number (TAN) of 0.7. The LVGO is quite unstable, attracts water, solufies dirt in the storage and engine/day tanks and plugs up fuel filters. The plugging of the filters disappears after the tanks are cleaned (by the Diesel). We are currently adding a chemical stabilizer to stabilize the Diesel.<br>
We Cautic Treated some LVGO samples in our lab one month ago and we see that the LVGO has become more stable as the untreated one.<br>
Our first question is if the other properties will also improve after the caustic treatment.<br>
<br>
Second, if we caustic treat our LVGO, we are aware of the waste problem we wil face. We will therefore also further treat our waste which we think will contain Sodium Naphthenate and Sulphuric components. We understand that such a waste treating system is called a Naphthenic Oil Residue (NOR) treater.<br>
Our question here is: (1) what will the expected waste products be appart from the Naphthenic Acid. (2) where can we sell the Naphthenic Acid and what is it used for.<br>
<br>
We would highly appreciate any feed-back on this matter as this infomation is needed to justify the investment costs of a Caustic Treating Facility for our Total production.<br>

First, let me say that catalytic hudrotreating would do a much better job of improving the quality of your diesel oil. <br>
<br>
Yes, the caustic should remove some organic sulfur compounds from the diesel as well as some organic acid oils. Whether your acid oils are naphthenic acids is questionable. I have always heard that very few crude oils contain naphethenic acids. California crude oils and some Russian crude oils do certainly contain naphthenic acids ... but not sure if any others do.<br>
<br>
In any event, the spent caustic will contain the sodium salts of your acid oils. Such sodium salts will be very raw<br>
soaps and gelling agents. Whether there is a market for them in your part of the world is question for you to determine.<br>
<br>
I would strongly suggest that consult Universal Oil Products in Des Plaines, Illinois, USA before you embark upon your caustic treating project.<br>

Dear Milton,<br>
<br>
Thank you for your reply. you are right to first contact specialists on this matter an we have therefore contacted an ASTM connected Diesel expert to advise us on this matter.<br>
I will surely contact Universal Oil Products.<br>
Thanks again.<br>

Hi

I recently came across an article which may help - address below

Kindly remember that LVGO &quot;as is&quot; may have a pour point sufficiently high for winter-grade diesel oil.
