17th Oxygen train largest

“ The new Air separation unit will be operated by Air Liquide and would supply Oxygen and all the gasses that Sasol needs in the Secunda operations,” said Benoit Potier (Air Liquide Chairman and CEO), “at Air Liquide, we understand how vital oxygen is. This is the world’s largest plant of its nature”

Sasol and Air Liquide have signed an agreement in 2015, under which Air Liquide will invest around €200 million in the construction of the largest Air Separation Unit (ASU) ever built at Sasol’s synthetic fuels and chemicals complex in Secunda, South Africa.
Today saw the official opening of the 17th train. This is a 5000 ton per day air separation train to supply oxygen and nitrogen to Sasol’s proprietary synthetic fuels and chemicals manufacturing process.
Owned and operated by Air Liquide, it is the first ASU that Sasol has chosen to outsource to a specialist of industrial gas production at this site. The start-up of the air separation unit (ASU) represents a new milestone in the partnership between Air Liquide and Sasol which brings to 17 the number of ASU’s delivered by Air Liquide over the last 40 years, with a total oxygen production capacity greater than 45,000 tonnes per day.
Using the latest air separation technology and economies of scale, this train is the most energy efficient oxygen train on the Secunda site with a significantly reduced impact on the environment. The oxygen capacity created enables Sasol to operate this complex up to the middle of the century, which is a cornerstone of the group’s Project 2050 strategy.
Crypton and Zenon is also generated as by products. The gases, which exist in tiny quantities in air, are used in a variety of industrial applications such as lamps, lasers, propulsion systems for satellites and medical applications. They are extracted by compressing and freezing air until the various gases are progressively liquified.
Sasol has also over the past 12 years invested R25 billion rand in a range of environmental programs to ensure that they sustainably manage and improve on their key safety health and environmental risks. “One key example in South Africa is the significant progress made recently with our volatile organic compound, the so-called VOC abatement programme. The R3,4 billion VOC abatement project has shown significant progress over the past financial year,” Said Bongani Nqwababa (Sasol Joint president and CEO), “from 46 kilo tons in 2016 to 41 kilo tons over the reporting period. Providing momentum for further emission reductions this year.”
“ The new Air separation unit will be operated by Air Liquide and would supply Oxygen and all the gasses that Sasol needs in the Secunda operations,” said Benoit Potier (Air Liquide Chairman and CEO), “at Air Liquide, we understand how vital oxygen is. This is the world’s largest plant of its nature”
Benoit also said, “not only is it the world’s largest but also the world’s most energy efficient plant of this nature.”
The Premier of Mpumalanga, Refilwe Mtsweni, was called to introduce the Minister of environmental affairs, Minister Molewa. Refilwe took time to elaborate on agreements to eradicate the sewer problems in Embalenhle.
Minister Molewa said that in 2012 South Africa adopted the national development plan. “This development that we are celebrating here today, that we are launching here today, is part of implementing that NDP.” Said Molewa, “we are happy that Sasol is continuing to work with us.” As she declared the unit officially open.
