Libya has the most important petroleum reserves of any kingdom in Africa and because creation begun in 1961 over 20 billion barrels of oil were produced. Libya is scheduled to arrive the mid-point of depletion of reserves in 2001 and this offers a well timed aspect at which to check the country of petroleum exploration in Libya.
While getting distinctive facts approximately residing platforms and complicated experimental systems have essentially absorbed the minds of researchers formerly, the improvement of high-throughput applied sciences has brought on the burden to more and more shift to the matter of reading collected info by way of organic functionality and biomolecular mechanisms.

5×N7+2×3. 145×108×N13×N2×N72=0 (13) 4 The other 7 equations after being processed are similar to the Eq. 13, no longer list. Take alkali-containing slag at production site as standard slag, the composition is shown in table 2. Take 10g slag and convert it into moles based on the percentage of slag composition in experiment program, these moles are used to represent a, b, c, d, e, f, g, h in the equations. 11 Hongxi Zhu and Linjiang Wang 31 Because the equation set is a higher mode nonlinear equation set, the determination cannot be used for solving the problem directly.
5 (6) tc ( d ) The tc(d) is “the characteristic reaction time” representing the required time of a completely oxidation of the sample. It can be regarded as criterion for determining the reaction rate. Usually, the larger the characteristic time is, the slower the reaction rate is. The active energy ∆E and constant Bt is obtained by fitting at least two temperature experimental data, and the oxidation kinetics curves at other temperatures could be quantitatively predicted by Eq. 5. Hongxi Zhu and Linjiang Wang If the temperature is the invariable, defining the constant H 2ν m written as ξ= pO2 19 2 K 0 D 0 exp(− ∆RTE ) as Bp , the Eq.
Especially now, as the Four High (High feed, High matte grade, High oxygen concentration, High volumetric heat capacity) technology  has being used to improve the single production ability of the flash smelting furnace, the furnace heat load has being increased correspondingly, and thus, the flash smelting furnace, especially the inner wall of reaction shaft, will be damaged more rapid [6,7]. Therefore, how to protect the reaction shaft is the main problem to be solved for intensified flash smelting process.
