The product is a mixture of refined liquid hydrocarbons derived from oil, consisting mainly of saturated hydrofluorocarbon-synthesis with chained hydrocarbons, and crude oil is often pressured and pressure-reducing fractions, solvent extraction and waxing, resulting in hydrogen refining [1]。
They include mineral hydrocarbons such as light, heavy fuel oil, lubricants and cool oil. Mineral oils can float on the surface of water bodies, affecting the exchange of oxygen between air and water bodies; they can also be dispersed in water, adsorbed to suspended particles or dissolved by micro-organisms in water in a lactation state, consuming dissolved oxygen in water and causing water quality to deteriorate。
