Although it has been a major exporter of urea, increasing Chinese government restrictions have restricted the seasonal window for exports.

The board of Petrobras has approved the resumption of operations at the company’s Araucária Nitrogenados SA (ANSA) site at Araucaria, Parana state. The plant, which has the capacity to produce 475,000 t/a of ammonia and 720,000 t/a of urea, has been idled 2020.

Prices in the West are unlikely to garner much support moving into the latter stages of Q2. The May Tampa ammonia settlement was settled by Yara and Mosaic at $450/t c.fr, down $25/t on the $475/t c.fr agreed for April. With seasonal domestic demand in the US drawing to a close 2H April, many had anticipated that either a rollover or a slight decline would be agreed.

Paradeep Phosphates Limited (PPL) and Mangalore Chemicals & Fertilizers Limited (MCFL) have agreed to merge.

More than 900 delegates from 400 companies and 56 countries gathered at the Hilton Downtown Hotel, Miami, Florida, 5-7 February, for the 2024 Fertilizer Latino Americano (FLA) conference. The event was jointly convened by Argus and CRU. We present selected highlights from this year’s three-day conference.

Urea. As February ended, urea prices found support in the US and Brazil while Europe remained subdued and Egypt struggled to find buyers. New Orleans was the one bright spot in the urea market – with NOLA prices benefitting from the meeting of suppliers and buyers at the TFI’s domestic conference. With positive sentiment all round, prices moved up $30/st, peaking at $390/st f.o.b. for March.

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.

Specialty fertilizer products represent a small volume, high value segment of the overall fertilizer market that’s been growing at around four percent per annum in recent years. Economic, environmental, regulatory and agronomic imperatives are driving up their adoption – and an overall shift from volume to value in the fertilizer market.

Prices will remain stable-to-soft across the board, though benchmarks could remain slightly more supported in the short-term than previously thought, with more significant declines likely in Q2-Q3.

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
