Carbon Black Feed Stock (CBFS)
What is it?
CBFS is a dark-colored viscous liquid that is obtained by doing fractional distillation of petroleum fractions at higher temperatures. It is the raw material for manufacture of carbon black, which is used by Tyre Industry.
Carbon black feedstock (CBFS) stands as a crucial component within the industrial landscape, renowned for its distinctive properties and multifaceted utility. Derived through a meticulous process of fractional distillation from select petroleum fractions, CBFS emerges as a viscous, dark-hued liquid, exuding versatility and potential. This prized substance serves as the foundational raw material in the intricate manufacturing process of carbon black, a ubiquitous element indispensable to the tire industry’s operations.
Applications
A small portion of this product is also used by processors to make various downstream chemicals like Agarbatti Oil, White Oil etc. This is also used for manufacture of Rubber Process Oils. There are two types of CBFS viz. High BMCI type and General type. “BMCI” (Bureau of Mines Co-relation Index) effectively measures the degree yield of Carbon Black. The higher the number, the better the yield of Carbon Black. Sulphur content in CBFS reduces the effect of BMCI value.
CBFS is used to produce Carbon Black, which is used in tyres and road paving, tyre reinforcements, black pigments (e.g. for road markings), and conductors. The stream also contains piperylene, which is used to produce copolymerization elastomers, petroleum resins, curing agents, pesticides, and perfumes.
Versatile feedstock source
- Naphthalene - used for phthalic anhydride, insecticides, and concrete plasticizers.
- Biphenyl - used for food preservatives, heat transfer fluids, and organic syntheses.
- Fluorine or anthracene - used for light emitting diodes, dyes, and wood preservatives.
- It is very cheap in price. Furnace oil is the most affordable liquid fuel available.
- It requires less maintenance.
- Furnace oil has proven to perform great in extreme cold.
- It is a pretty much stable, combustible, non-explosive product.
- The fuel oil is much safer, more efficient, and gives more warmth than natural gas.
- It gives you a longer furnace and boiler life, so you face less depreciation.
- Apart from that, furnace oil is also more common and cost-effective to use.
