Olefin production

In 2009, the capacity utilisation of both plants calculated for ethylene decreased from 92% to 86% as a consequence of the lower ethylene sales to BorsodChem.

Where olefin is produced

The Olefin-1 Plant started up in 1975 and the Olefin-2 Plant came on line in 2004, both utilising Linde technology. 

Calculated for ethylene, the annual total capacity of the two plants is 660 kt/year.

Feedstock and by-products

Feedstock is supplied by MOL Group which also processes a major portion of resulting by-products such as isobutylene, benzene and gasoline fractions, to produce MTBE and benzene, or as components of blended gasoline. Quench oil is utilised as feedstock to make carbon black, by Tiszai Columbian Koromgyártó Kft., located in the TVK industrial complex.

Utilisation and capacities

TVK polymer plants process most ethylene and all propylene output.

Ethylene, produced in the olefin plants is sold to BorsodChem. In the 4th quarter of 2009 we concluded a contract with Synthos, one of the largest chemical companies in Poland for the supply of raw C4 fraction during 2010-2012. The surplus propylene produced in the olefin plants are sold to Slovnaft Petrochemicals and external customers.
