Engineering and consulting company ÅF, Sweden, has been commissioned by Stora Enso (Sweden) to build a new lean gas system at its Skutskär Mill in Sweden to reduce sulfur emissions and improve the smell in the surrounding area. The assignment is an end-to-end solution worth about SEK 10 million. The new system is expected to be operational in autumn 2017.

The assignment includes project management, process design, piping design, electrical and automation, construction, and fire safety.

"A major technical challenge is finding an optimal process design that connects the dispersed odorous gases in the factory to a pipe system for combustion," said Stefan Hännestrand, project manager at ÅF. "This project requires expertise and collaboration between disciplines."

In addition to a new lean gas system, ÅF was entrusted to modernize the control systems on the roll cutters at Skutskär Mill, a project that has been ongoing since 2015.

ÅF was also recently commissioned by Stora Enso to plan a new chemical plant at Skoghall Mill.
