KBR Helps Linggu Chemical’s Urea Aqueous Solution Upgrade Project Reach Full Production Capacity Author/Source: KBR Technology Date: 2022-11-08 Clicks: 39 On October 31, 2022, the successful and safe operation of the first phase of the synthetic ammonia production upgrade project at Linggu Chemical Group Co., Ltd. marked the complete success of this upgrade project, which enables the company to produce 550,000 tons of synthetic ammonia and 1.3 million tons of urea aqueous solution per year. As a global leader in synthetic ammonia technology, KBR entered into a partnership with Linggu Chemical Group in June 2018. Under the terms of the contract, KBR was responsible for providing services related to the technological upgrade project for urea aqueous solutions at Linggu Chemical’s facility in Yixing City, Jiangsu Province. These services included the provision of Synloop technology for the synthetic ammonia production process, design of process packages, detailed design support to the client, and on-site assistance during commissioning. Since the project officially commenced in June 2018, upgrades were carried out during that period on the upstream air separation unit and syngas plant. Despite various adverse factors such as the impact of the COVID-19 pandemic, through the close cooperation between KBR and the project implementation team of Linggu Chemical, the mechanical inspection of the key equipment, namely the ammonia synthesis tower, was completed in February 2022; catalyst loading was finished in March, and the plant reached full operational capacity in early May. Under the safety production plan, Linggu Chemical began official production in late October, and by October 31 it was operating at full capacity with a production capacity of 1,500 tons per day. “It was a pleasant collaboration,” said Shan Yajun, project manager for Linggu Chemical’s urea aqueous solution technology upgrade project and head of the ammonia synthesis workshop. “KBR not only provides stable and reliable ammonia synthesis technology but also possesses strong project execution capabilities. They always take the initiative to understand our progress and challenges, coordinate actively, provide full support, and offer solutions in a timely manner, ultimately helping us achieve production targets on schedule. We are very satisfied with this. ” Cao Ran, General Manager of KBR in China, said, “I am pleased to see that the technological upgrade project for urea aqueous solutions at Linggu Chemical has been successfully brought online. This is the result of our joint efforts with the client, and I would also like to thank Linggu Chemical for its trust and understanding toward us.” Since entering the Chinese market in 1972, KBR has not only taken on 8 out of the 13 large-scale ammonia synthesis projects carried out in the early days of the People’s Republic of China, but has also successfully participated in the construction of over 100 industrial plants in the country. We are willing to work hand in hand with industry peers like Linggu Chemical to promote the healthy and sustainable development of the sector. ” KBR is a market leader in ammonia synthesis technology, holding a market share of around 50% of the world’s licensed ammonia production capacity. Furthermore, KBR holds multiple industry records, including the largest single synthesis tower facility, the lowest net energy consumption, and the longest continuous operation time. KBR was the first company to bring a clean synthetic ammonia technology with a capacity of 6,000 tons per day to market, while Ammonia 10,000 represents an advancement in synthetic ammonia technology with a capacity of 10,000 tons per day; it will help drive the industry toward a future based on hydrogen with zero emissions. Since 1943, KBR has licensed, designed, or built 252 new ammonia synthesis plants worldwide.
