| oil production (The petroleum industry is a complex industry utilizing complex combination of interdependent operations engaged in the storage and transportation, separation of crude molecular constituents, molecular cracking, molecular rebuilding and solvent finishing to produce petrochemical products. Treatment may involve oil separation, precipitation, adsorption, and biological treatment. The refining operations can be divided into four major steps: separation, conversion, treating, and blending. The crude oil is first separated into selected fractions (gasoline, kerosine, fuel oil, etc.). Some of the less valuable products such as heavy naphtha, are converted to products with a greater sale value such as gasoline. The final step is the blending of the refined base stocks with each other and various additive to meet final product specifications. The major pollutants emitted are sulphur oxides, nitrogen oxides, hydrocarbons, carbon monoxide, and malodorous materials; chain) | производство на петрол | |
