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.

Tampa ammonia contract prices increased dramatically during September, from $395/tonne c.fr to $575/ tonne c.fr. The main culprit was plant outages and reduced production at several plants in the region. The tight supply situation was exacerbated by a delay to the restart of Ma’aden’s 1.1 million t/a ammonia plant in Saudi Arabia.

Distributed and carbon-free ammonia production with Stami Green Ammonia technology offers a highly competitive alternative to conventional grey processes, paving the way for scaling up and sustaining local communities with renewable energy sources.

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.

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.

Low carbon production is attracting considerable attention to using syngas derivatives as fuels, but there are considerable logistical and commercial barriers to overcome.
