Press Release

HOUSTON - (September 1, 2016) - KBR, Inc. (NYSE: KBR) and its wholly owned subsidiary, Weatherly Inc. announced today the launch of the new Weatherly Dual Pressure Nitric Acid Technology. This technology enables economically viable production of Nitric Acid in large scale (over 1,000 Mtons/day), as part of large fertilizer production complexes.

Weatherly's new technology produces nitric acid at an operating cost that is $4 to $5 per ton less than competing dual pressure plants of the same capacity. This is possible due to its more efficient heat recovery design that converts tail gas heat to energy, which in turn is used to power up the plant.

In addition to lower cost of production, Weatherly's Dual Pressure plants require up to 10% less capital investment than competing designs due to their compact design and proven vertical reactor, requiring less steel and piping than traditional plants.

"The launch of this technology confirms KBR's commitment to continue to bring to market innovative technologies that help our clients improve their competitive position," said John Derbyshire, President of KBR Technology & Consulting. "We recognize the need for larger nitric acid plants as part of larger fertilizer complexes worldwide, so we expanded our portfolio to serve this market."

"The addition of this Dual Pressure design gives us a more complete portfolio," said David Boyd, Director of Operations of Weatherly Inc. "While we are already proven market leaders in smaller-scale nitric acid production with our superior High Mono-Pressure Nitric Acid technology, we can serve our clients regardless of their production volume targets."

Weatherly Inc. will be launching this technology at the AN-NA 2016 Conference on September 18, 2016, in Eindhoven, the Netherlands.
