TOYO has a long history in urea granulation technologies and has recently added two new technologies to its product line-up.

With the current focus on decarbonising ammonia production, Tom Davison of Johnson Matthey explains the important role of high activity ammonia synthesis catalyst in the production of green ammonia.

Jiangsu Sailboat Petrochemical has started up a CO2 -to-methanol plant at the Shenghong Petrochemical Industrial Park. The plant was developed in conjunction with Iceland’s Carbon Recycling International (CRI), with the plant brought to life in under two years from the initial contract signing. The methanol plant uses CRI’s proprietary emissions-to-liquids (ETL) technology, transforming waste carbon dioxide and hydrogen gases into sustainable, commercial-grade methanol. According to CRI, uses 150,000 t/a of carbon dioxide sourced from waste streams at the large petrochemical complex as feedstock, significantly reducing emissions that would have otherwise been released into the atmosphere. The plant has the capacity to produce 100,000 t/a of sustainable methanol, used primarily to supply Jiangsu’s methanol to olefins facility to produce chemical derivatives, including sustainable plastics and EVA coatings for solar panels. This is expected to reduce the reliance on fossil-based methanol to drive more sustainable value chains and carbon footprint reduction initiatives across various sectors, such as industrial manufacturing and renewable energy.

Ballestra is taking a new approach to improving nutrient use efficiency by moving methylene-urea production to the fertilizer industry. Massimo Gori and Svet Valkov of Ballestra discuss the technology and benefits of having a slow-release fertilizer that uses a product from within the fertilizer industry.

Sumit Rao of Hindustan Platinum Private Ltd describes two recent start-up issues with catalyst gauze packs at a nitric acid plant, and their remediation to allow production to continue.

With low carbon ammonia and methanol being considered not just for their chemical and fertilizer uses, but as fuels, can we make enough of them to fill our energy needs?

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.

While the world’s attention has been grabbed by the terrible situation in the Middle East, the Russian-Ukrainian conflict continues to drag on. Of particular concern in recent months has been the deal to allow export of grain from Odessa, which lapsed in July 2023, a year after it first began. The deal had allowed 33 million tonnes of grain to be exported, around 60% of it to the developing world. However, Russia had always insisted that continuing with the deal was contingent on (a) a resumption of Russian ammonia exports via Odessa and (b) removing SWIFT payment restrictions on the Rosselkhozbank agricultural bank, allowing easier export of fertilizer. Fertilizers remain exempt from sanctions on Russia, but the difficulty in securing payment, the closure of the ammonia pipeline to the Black Sea, and high maritime insurance rates for traversing the Black Sea have made exports much more difficult. And although Ukraine continues to export grain, now mostly via rail to ports like Ismail and Reni on the River Danube, Russia has done its best to disrupt this, striking ports and warehouses and laying mines in shipping lanes. Around 300,000 tonnes of grain has been destroyed, according to Ukraine, as well as up to three ships hit by mines and one possibly by a missile on November 8th. Furthermore, bottlenecks in rail transit and port capacity and the difficulty in getting ships to the ports mean that actual volumes of grain exported are considerably reduced, with only around 700,000 tonnes exported via the Danube Ports from August to the start of November.

One of the things that produced a lot of worried news headlines over the past couple of years is whether the energy transition is likely to lead to a shortage of sulphur as we switch away from fossil fuels on a large scale. As we’ve discussed in this magazine, those fears are overblown, certainly in the medium term future. Peter Harrison of CRU tackled the issue in his sulphur markets presentation at the recent Sulphur and Sulphuric Acid conference in New Orleans, and while he did admit to some reduction in sulphur supply from oil in the 2030s and increasing into the 2040s, increased sulphur recovered from sour gas is likely to more than make up for that at least until the 2040s. But one of the things that did strike me about his presentation is the extent to which the energy transition is indeed already changing the way that the sulphur market works, and will increasingly do so over the next few years.

The merchant market for sulphuric acid is only a small slice of overall global acid demand, dominated by smelter acid producers. Increasing replacement of acid imports by dedicated sulphur burning acid plants by end use consumers is reducing the scope for merchant sales and could lead to overcapacity in the near term.
