Cyclic hydrocarbons; benzene
HS v2017 Code: 290220
About cyclic hydrocarbons; benzene
HS code 290220 covers the classification of benzene, a key cyclic hydrocarbon compound. Benzene is a widely used and essential chemical in the petrochemical industry, serving as a building block for a diverse range of products. Its importance spans various sectors, including the production of fuels, solvents, plastics, and pharmaceuticals, making it a crucial component of the global economy.
Production process
Benzene is primarily produced through the catalytic reforming of petroleum fractions, a process that involves the rearrangement of hydrocarbon molecules to increase the aromatic content. This is typically done in specialized refineries, where the crude oil feedstock is subjected to high temperatures and pressures in the presence of a catalyst to enhance the formation of benzene and other aromatic compounds.
Production inputs
The main inputs required for the production of benzene under HS code 290220 include crude oil or petroleum fractions, catalysts (such as platinum or rhenium-based catalysts), and energy sources to power the refining process. Additionally, specialized equipment, such as distillation columns, reactors, and separation units, are essential for the efficient extraction and purification of benzene from the refinery stream.
Production outputs
The primary output of HS code 290220 is purified benzene, which is then used as a feedstock for the production of a wide range of downstream products. These include 290511 ethylbenzene, 290524 cumene, 290730 phenol, and 290411 nitrobenzene, all of which are important intermediates in the manufacturing of various chemicals, plastics, and other industrial materials.
