Definition: The “Polystyrene” belongs to the Aromatics family (BTX) by the Benzene. Polystyrene is a polymer of the Styrene as monomer where the Styrene itself is produced by dehydrogenation from the Ethylbenzene, a combination of Benzene and Ethylene. Comments: Polystyrene is a plastic made by polymerising styrenes. It is made in two types: a “crystal” polystyrene (extremely transparent) and […]
Definition: “Butadiene” is the head of the C4 olefins family. Butadiene is a gas that condensates at -4.5°C. Mainly produced as byproducts from Ethylene by Ethane by steam cracking at high temperature (900°C), the Butadiene can also be obtained by Butane dehydrogenation or from Ethanol. Comments: Butadiene is mostly converted into Styrene Butadiene or Styrene Butadiene Rubber (SBR) more well known as synthetic Rubber Polybutadiene is also used […]
Definition: “Propylene” is the common name given to the Propene. It is a gas, not to be confused with the Propane. Propylene may also be called Methylethylene. Comments: From process perspective, the Propylene is a byproduct as produced in parallel of the Ethylene during the cracking operations in the steam cracker as shown in the flowchart above. […]
Haldia Petrochemicals Ltd (HPL) is a competitive modern naphtha based Petrochemical Complex located 125 kms from Kolkata, at Haldia, West Bengal, India. HPL is the second largest petrochemical industry in India with a total capacity equivalent to 7, 00,000 TPA of ethylene. Now HPL is planning a $1 billion (Rs 4,000 crore) capital expenditure project over […]
Definition: “Rubber” is the common name given to Styrene Butadiene or Styrene Butadiene Rubber (SBR). Comments: Produced out of the butadiene, the C4 Olefins family, either by fraction distillation in refinery either as byproducts of the Ethylene in the steam cracker, the Rubber is mostly used because of its adhesive performances for tyres, sealants, sho soles, coatings. […]
Definition: “Ethylene” is one of the most important Olefin products. It is a colourless, flammable gas with a slightly sweet odor. As shwon in the diagram below, it comes directly from the cracking in a steam cracker of different feedstocks: Gas such as ethane, propane, butane Liquid naphtha coming from oil refineries. Comments: The chart below shows the […]
Honan Petrochemical Corp. has signed a MOU with Krakatau Steel for a land in Cilegon, Indonesia to build a new naphtha cracker and downstream units. The feasibility study of the project has started and would include: 1 million t/y Ethylene 550,000 t/y Propylene 600,000 t/y Polyethylene (PE) 600,000 t/y Polypropylene (PP) 700,000 t/y Monoethylene Glycol […]
Definition: “Olefin” is the common name given by the “Petrochemical” industry to the Alkene chemical products. The “Olefins” are classified in two families, the: “Monoolefins“, such as the “Ethylene” and “Propylene“ “Diolefins“, such as the “Butadiene” and the “Isoprene“ Comments: As we can see from the diagram above, the “Olefins” may be produced through a steam”Cracker” […]
