Under the agreement, KBR will supply its proprietary ammonia technology to increase plant capacity significantly to 2100 million tpd with improved efficiency.

The company will utilise its revamp technology KRES™ (KBR Reforming Exchanger System) in conjunction with its 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.
