KBR awarded Plinke technologies contract by Hanwha

By Mary Page Bailey |

KBR, Inc. (Houston) announced that it has secured a contract for its Plinke nitric acid concentration and spent acid recycling technologies from Hanwha Solutions for its new production facilities at Yeosu, South Korea. 


Under the terms of the contract, KBR will provide a license, basic and detailed engineering design, technical services, and proprietary equipment to Hanwha for the production of 160,000 metric tons per year (m.t./yr) of concentrated nitric acid and treatment and recycling of 240,000 m.t./yr of spent sulfuric acid. Nitric acid and its derivatives are processed for the production of various materials such as flexible polyurethane foams which help manufacturers in the furniture, bedding and automotive sectors to achieve sustainability and energy conservation objectives, or precision chemicals such as those used in the semiconductor industry.


“We are privileged to receive this award from Hanwha, further consolidating our valuable relationship,” said Doug Kelly, KBR President, Technology. “This is the fourth Hanwha plant where our energy-efficient Plinke technologies will be implemented due to their technological and environmental leadership qualities.”
