Producers of surfactants, surfactant intermediates, high-purity alumina and related speciality products Sasol Olefins & Surfactants (O&S) announced in July that it had reached an important milestone in the expansion of its capabilities with the production of its new ALCAT TEAL highly purified triethyl aluminium product.

Production at the new TEAL plant in Brunsbüttel, Germany, which went on line in June 2012, has been running smoothly for nearly a year. The full functionality of the supply chain has been proven with successful product supplies to such customers as Sasol Polymers in South Africa.

Importantly, Sasol O&S has now obtained further approvals for the use of ALCAT TEAL in applications such as the Novolen process, a polypropylene gas-phase technology.

The new facility has an ini- tial yearly TEAL production capacity of 6 000 t. Sasol O&S has more than 50 years’ experience in dealing with aluminium alkyls; therefore, adherence to the highest safety standards was guaranteed from the start.

By applying its unique know-how to the complete logistics chain from production to global customer deliveries, Sasol O&S has provided for seamless container rotation.

“With the existing local infra- structure and expertise, particularly in handling special chemicals, our Brunsbüttel plant is in an ideal position to produce TEAL reliably and in high quality and quantities, offering our global customers maximum product and supply security,” says Sasol O&S MD Eric Stouder.

He adds that, with the com- pany’s latest approvals for the application of ALCAT TEAL and its proven logistics chain, it is ready to serve the growing global market.

ALCAT TEAL is used as a cocatalyst in the production of polyethylene and poly- propylene, and also as a reactive intermediate in the manufacturing of linear alpha olefins.

Meanwhile, energy and chemicals company Sasol also announced a series of engineering and technology provider appointments in July, as it continues to advance the front-end engineering and design (Feed) of its ethane cracker and derivatives project.

“We are delighted to be working with these contractors and technology partners in executing our project,” says Sasol executive VP for the US Mega projects Johan du Preez.

He points out that the selected companies are leaders in their respective fields and have the technologies, systems and expertise to help the company deliver the project on schedule, improving the com- pany’s return on investment.

“Engineering construction company Fluor is the main Feed contractor for the ethane cracker and derivatives project. Individual engineering services agreements for the development of basic engi- neering packages have been concluded with engineering com- pany Toyo Engineering for the linear low-density poly- ethylene (LLDPE) plant, multi- disciplinary engineering company Mitsui Engineering & Ship-building for the low-density polyethylene (LDPE) plant, and global engineering firm Samsung Engineering America for the ethylene oxide (EO) and mono-ethylene glycol (MEG) units,” he says.

Project management, engineer- ing and construction company Technip, engineering company Stone & Webster Process Tech-nology and chemicals and pet- roleum company ExxonMobil Chemical Technology Licensing have been selected for the ethane cracker and the LDPE, LLDPE and EO/MEG processes respectively.

In addition, Sasol will use its own proprietary technologies for the Tetramerisation, Ziegler alcohol and Guerbet alcohol units. Emerson Process Man-agement, a global business of Emerson, has been appointed the main automation contractor for the project.

Further, p

roject delivery and consulting services company WorleyParsons has been contracted to support Sasol’s own project execution team as part of an integrated project management team. WorleyParsons’ systems, tools and local expertise will be used to enhance the Sasol team that is overseeing the project.
