The US is experiencing a new boom in nitrogen projects, with a number of carbon capture ammonia plants under development.

Low carbon intensity hydrogen and ammonia production schemes from KBR, Air Liquide, Mitsubishi Heavy Industries, Casale and Johnson Matthey.

KBR offers an end-to-end digitalisation solution specifically designed for green ammonia plants to balance the available renewable resources and consistently deliver the lowest levelised cost of green ammonia (LCOA). This article outlines some of the key modules of the KBR end-toend digitalisation solution developed to overcome the challenges in green ammonia operation and achieve best in class, safe and reliable plant operation.

In spite of nearly two years of western sanctions, Russian exports of nitrogen fertilizer have recovered almost to pre-war levels, while high prices led to record earnings in 2022.

BHP has approved an investment of $4.9 billion (CAD 6.4 billion) in stage two of its Jansen potash project (Jansen Stage 2) in Saskatchewan, Canada.

Proman has signed a memorandum of understanding (MoU) with Mitsubishi Corp to collaborate on the development of a blue ammonia plant at Lake Charles, Louisiana. This new facility will aim to produce around 1.2 million t/a of low carbon ammonia, making it one of the largest of its kind in the world. The plant will incorporate carbon capture and sequestration technology. Proman says that this development aligns with the company’s commitment to sustainability and reducing greenhouse gas emissions. The proposed ammonia plant will be located at Proman’s existing site in Lake Charles, adjacent to its gas-to-methanol plant, which is also currently being developed.

Rohit Khurana and Umesh Jainker of KBR presented a technical paper on this topic during the 2013 Asian Nitrogen + Syngas Conference. It can be found in the UreaKnowHow.com E-Library with the title: ”Replacing ammonia plant catalyst with maximum efficiency and lowest cost”. The paper addresses the importance of de-dusting catalyst beds before commissioning and the serious impacts on the plant if not performed thoroughly. Many ammonia plants have faced problems related to the plugging of exchangers, pipe choking, pressure drop increase of the downstream catalyst beds and separators or foaming in the CO 2 removal section which could be caused by the presence of catalyst dust. Most of these problems have led to either decrease in the efficiency of the plant or operation at lower throughputs. The paper presents the critical steps and procedures for proper dedusting of the catalyst beds before commissioning. In addition, the foaming problem in the CO 2 removal section associated with catalyst dust is discussed signifying the importance of cleaning the CO 2 removal system and solution. The role of filters in the CO 2 removal section was also emphasised.

CF Fertilisers UK Limited, a subsidiary of CF Industries, says that it plans to permanently close the ammonia plant at its Billingham fertilizer complex in order to secure the long-term sustainability of its business in the UK. The Company intends to continue to produce ammonium nitrate (AN) fertiliser and nitric acid at the Billingham site using imported ammonia, as it has for the last 10 months following its decision to temporarily idle the plant in August 2022.

Prior to the covid pandemic, sub-Saharan Africa had been the fastest growing market for new fertilizer demand. However, the combination of pandemic related disruption, followed by the dislocations caused by the war in Ukraine, have pushed up prices and led to falling demand across the continent.
