ethane

Ethane Cracking Unit

The Olefin or Ethane Cracking Unit produces the necessary feed for the low/medium/High-density polyethylene units. The construction of this unit began in March 2001 by concluding the engineering and procurement contracts (in partnership with Technip France and Nargan Iran), leading to its full operation in 2007. The annual production capacity of this unit is one million tons of ethylene. Of this, about 600,000 tons (maximum) are consumed within the complex for feeding the downstream units and producing low/medium/High-density polyethylene; and 175,000 tons are sent to the EBSM unit in Pars Petrochemical Company. The remaining 225,000 tons is exported (via a jetty adjacent to the complex) to international markets, and this is considered a technical and trading opportunity for the company since, in case of a drop in production or non-requirement by the downstream units, the surplus ethylene can always be exported. The Olefin Unit needs 1.267 million tons of ethane for producing one million tons of ethylene. This ethane is supplied from Pars Petrochemical. The outstanding features of the ethylene produced by Arya Sasol are enumerated below.
