Crude oil is a naturally occurring, unrefined petroleum product that is made up of a mixture of hydrocarbons and other organic compounds. It is the raw material that is used to produce a variety of refined petroleum products, including gasoline, diesel fuel, and heating oil. Crude oil is extracted from the earth through drilling and is transported to refineries where it is processed and refined into various products. Crude oil has a wide range of physical properties. Crude oil is made up of 84.5% carbon, 13% hydrogen, 1â??3% sulfur, and less than 1% each of nitrogen, oxygen, metals, and salts. REBCO is a specific type of crude oil that is produced in Russia and the surrounding regions. It is a high-quality crude oil that is known for its low sulfur content and low viscosity. The middle east light crude oil is also high-quality crude oil. The GOST 51 858-2002 specification refers to the Russian standard for REBCO, which outlines the crude oils characteristics and performance requirements. Gost 51 858 2002 offers from exporters, manufacturers, suppliers, wholesalers and distributors globally by price, and quality of the oil. REBCO is an important commodity in the global energy market, and it is carefully regulated to ensure that it meets the necessary standards for safety and performance.
