Abstract:

Given the immense importance of crude oil to contemporary civilization as a raw material for several chemical and petrochemical businesses as well as a source of energy, in this study we assess the properties of specific Yemeni crude, and fuel oils, in particular, Masila crude oil and Mareb crude oil.         
These crudes' and fuel oils' general requirements are established.

And contrasted utilizing the available data in the specialist literature with a few other regional and global kinds, such as Brent and West Texas benchmark crudes. It is discovered that the lightest and sweetest crude oil is Mareb crude oil blend. The aforementioned samples contained eleven metals and heavy metals, of which the most prominent ones were identified by atomic absorption spectroscopy and the ICP technique as (Na, K, Mg) and (V, Co, Ni). Figures depict the sequence in which the metal concentrations in Yemeni crude oils were found:

Due to the high significance of crude oil to modern society as a source of energy and as raw material for a wide chemical and petrochemical industries; in this study, we evaluate the characteristics of certain Yemeni crude, and fuel oils specifically Mareb crude oil blend, Masila crude oil.   The general specifications of these crudes and fuel oils are determined and compared with some other regional and international types including Brent and West Texas benchmark crudes using the published data in the specialized literature. It is revealed that Mareb crude oil blend is the lightest and sweetest crude oil followed. the levels of heavy metals present in the crude oil For heavy metals, the range of values were Ag (0.003- 0.0614), Ca (3.24-1876), Cd (<0.001-0.0195), Co (<0.0018-0.1615), Cr (<0.0018-1.776), Fe (1.684 -94.3), K (0.0320-12.59), Na (0.04 -31.94), Ni (0.1894-1.60), Pb (0.0534-1.31), V (0.0667- 0.45) .  In many nations, the quantities of metals in the investigated sample were generally lower than those in crude oil and fuel oil. This indicates that Yemeni fuel oil and petroleum are of the highest caliber.  In general, the analyzed sample's metal contents were lower than those of crude oil and fuel oil in many different nations. This indicates that Yemeni fuel oil and petroleum are of the highest caliber.
