Anyone with Experience Processing Nemba Crude?

SIr, I suggest you review this for Nemba Crude, since Chevron is also investing in Nemba crude:

You can get more information for this by typing the key word "Nembo Crude" (without quotes) into google.

On reviewing the data Chevron has posted, the following are my judgements on Nemba crude:

1) Highly paraffinic

2) low sulfur

3) low-moderate nitrogen

4) low metals

5)low cabon residue

5)high gravity

I would expect the naphtha cut to be highly paraffinic with low octane, and fair to good yields on catalytic reforming, but tending to make more LPG

I would expect excellent yields on catalytic cracking, but even better yields on hydrocracking.

I would expect the diesel cut to be high quality with a high cetane number, but with potential for high wax content which MAY cause low temperature problems with gelling or cold filter plugging problems, requiring a pour point depressant.

I would expect excellent kerosene/jet fuel characteristics following mild hydrotreating or even just mercaptan removal, but again wax content MAY be an issue.

The low acidity value suggests low risk of naphthenic acid corrosion and the low sulfur contents makes this a 'sweet' crude.

I suggest you load the crude assay into your LP model and see what the economics are. I would suggest obtaining quality data (and yields) on the cuts before making any economic evaluation.

I would expect the crude to be 'easy' to process into high quality motor and turbine fuels, with low bottoms or heavy fuel oil yields, no asphalt (too waxy)--an excellent candidate for 'hydro-skimming' refineries or as a 'diluent' for heavy crudes, though that use 'wastes' the premium quality characteristics of Nemba.

Nemba is likely not a good candidate for aromatics production, but the naphtha cut may be a good feedstock for olefines production.

Excellent analysis....thanks a lot ........
