Italy’s Saipem has won a front-end engineering design (FEED) contract from Sonatrach for an integrated phosphate fertilizer project in Algeria.

To cope with higher demand for green and blue ammonia, new ammonia terminals will be required and must be designed with respect to social and environmental challenges, as well as local permitting regulations and safety requirements. Saipem has developed a wide range of solutions to tackle those challenges and requirements by offering large-scale liquid ammonia storage and import/export terminal facilities supported on gravity based structures.

The production of urea, a critical component in the fertilizer industry, involves highly corrosive environments, particularly in the high-pressure sections of the process. This necessitates the use of advanced materials that can withstand such aggressive conditions to ensure long life and efficiency of urea production plants. Alleima, Stamicarbon, Saipem and TOYO report on their advanced material and equipment solutions for the urea industry.

Methanex Corporation has entered into a definitive agreement to acquire OCI Global’s international methanol business for $2.05 billion. The transaction includes OCI’s interest in two world-scale methanol facilities in Beaumont, Texas, one of which also produces ammonia. The transaction also includes a low-carbon methanol production and marketing business and a currently idled methanol facility in the Netherlands.

Casale, Saipem, Stamicarbon & Toyo Engineering Corporation showcase a selection of innovative technologies that have recently been brought to the market.

Already the world’s largest exporter of sulphur, Abu Dhabi continues to expand its sour gas production and sulphur output.

A summary of papers presented at CRU’s Nitrogen+Syngas conference, this year held at the Gothia Towers in Gothenburg, Sweden.

Mark Brouwer and Jo Eijkenboom of ureaknowhow.com examine the major shifts in global urea production. They also discuss the future of the urea industry and, in particular, how the sector is being affected by the increasing focus on low-carbon ammonia production.

Every urea plant is also a water plant as the overall reaction starts with two molecules of ammonia and one molecule of carbon dioxide resulting in one molecule of urea and one molecule of water. Further water is added to the process via the steam ejectors in the evaporation section. All this water, which is contaminated with ammonia, carbon dioxide and urea plus possibly other contaminants like formaldehyde, methanol, oil, etc is collected in an ammonia water tank and then sent to a wastewater treatment section. The purpose of the wastewater treatment section is to reduce the ammonia, carbon dioxide and urea levels to acceptable levels. First the wastewater is treated in a first desorber column, where LP steam is used to strip off the ammonia and carbon dioxide, reducing the ammonia content from approx. 6-8 wt-% ammonia to approx. 1 wt-% ammonia. Nothing happens with urea in the first desorber as temperatures are too low to hydrolyse the urea back to ammonia and carbon dioxide. This takes place in the next step, in the hydrolyser, which can be quite a large counter current column operating with MP steam at approx. 23 bar (Stamicarbon design) or a horizontal deep hydrolyser operating at approx. 33 bar (Saipem design, refer to figure). Downstream of the hydrolyser there is another desorber column to strip off the remaining ammonia and carbon dioxide. Nowadays, boiler feed water quality can be realised by modern wastewater treatment. But at higher plant loads the operating margin in the wastewater treatment can become too small leading to higher ammonia and urea levels during certain operating conditions… n

OCI Global says that it has reached an agreement for the sale of 100% of its interest in its large-scale nitrogen fertilizer subsidiary the Iowa Fertilizer Company LLC, located in Wever, Iowa, to Koch Ag & Energy Solutions for $3.6 billion. Completion of the transaction remains subject to US anti-trust approval and other customary closing conditions. The transaction is expected to close in 2024. Morgan Stanley & Co. International plc is serving as financial advisor to OCI on the transaction. IFCO produced 1.2 million t/a of urea ammonium nitrate (UAN) in 2021 and 700,000 t/a of anhydrous ammonia, as well as 700,000 t/a of diesel exhaust fluid (DEF).
