HOUSTON (July 27, 2017) KBR, Inc. (NYSE: KBR) today announced that it has been awarded a contract by Dorogobuzh JSC (owned by JSC ACRON) to provide licensing and basic engineering design (LBED) to revamp an ammonia plant originally built by KBR located in the Dorogobuzh, Smolensk region of Russia. Under the agreement KBR will supply its proprietary ammonia technology to increase plant capacity significantly to 2100 MTPD with improved efficiency.

KBR will utilize its industry leading revamp technology KRESª (KBR Reforming Exchanger System) in conjunction with KBR's True Cold Wall Add-on Converter to achieve low project cost revamping to enable Dorogobuzh to produce low cost ammonia to meet increasing captive demand.

"The application of KRESª in conjunction with KBR's reliable add-on ammonia converter provides low cost revamping to Dorogobuzh and numerous similar plants in the region," said John Derbyshire, President of KBR Technology & Consulting.

"We are pleased to contribute KBR's innovative technology solution for natural gas monetization in Russia," Derbyshire continued. "KBR is a leader in helping clients debottleneck their ammonia plants and achieve greater production capacities, process efficiencies and reliability."

Revenue associated with this project is undisclosed and was booked into backlog of unfilled orders for KBR's Technology & Consulting Business Segment in the second quarter of 2017.
