The project prevents the annual flaring of around 762 tonnes of an
ethylene-ethane mixture, which was previously burned during hydrogenation
reactor changeovers and maintenance shutdowns at the olefins unit, Chief Executive
Mohammadreza Heidarzadeh said.
Heidarzadeh said the flaring not only caused significant economic
losses but also contributed to higher environmental emissions. As a result, the
company prioritised a project aimed at reducing flaring, recovering valuable
gases and limiting technical and environmental damage.
“The implementation of this project has reduced annual flaring by
about six hours and prevented the loss of 762 tonnes of ethylene and ethane
mixtures,” he said, adding that the total economic benefit amounted to roughly
$408,000.
Reducing flaring is part of Arya Sasol’s broader clean production
strategy and environmental commitments, Heidarzadeh said. He noted that despite
the absence of a clear national standard defining permissible flaring limits,
the company has invested about $2.5 million in two major projects.
According to the company, these initiatives enable the annual recovery
of around 2,500 tonnes of ethane and ethylene and prevent the emission of
approximately 7,700 tonnes of carbon dioxide.
