Venkat Pattabathula, a member of the AIChE Ammonia Safety Committee, reports on the American Institute of Chemical Engineers’ Safety in Ammonia Plants and Related Facilities Symposium, held at the Hyatt Regency in Chicago, USA, on 11-15 September 2022.
Maersk has ordered six more 17,000 teu (twenty-foot equivalent unit) container ships capable of running on methanol from Hyundai Heavy Industries (HHI). The order brings Maersk’s total order book of dual-fuel vessels capable of running on methanol to 19. Maersk said the new ships will replace existing tonnage in its fleet when they’re delivered in 2025. When all 19 vessels on order join the fleet and replace older tonnage, CO2 savings will be around 2.3 million t/a, according to Maersk. Maersk has committed itself to renewable methanol as a pathway to zero emissions shipping. Its first vessels are due for delivery from Q1 2024. The company has also signed several green methanol fuel supply agreements and joined a partnership to create the first e-methanol plant in Southeast Asia. Maersk is also working with Japanese trading house Mitsui and the American Bureau of Shipping (ABS), to jointly conduct a detailed feasibility study of methanol bunkering logistics in Singapore.
Maire Tecnimont subsidiary MyRechemical has been awarded a basic engineering contract for a waste to methanol and hydrogen plant to be located in Empoli, Tuscany. The scope of work includes the basic engineering design of the plant and the provision of necessary documentation to start the plant’s public authorisation process with the Tuscany region. The basic engineering phase is expected to be completed by the end of 2022. Once completed, the plant will process 256,000 t/a of non-recyclable waste and will produce 125,000 t/a of methanol and 1,400 t/a of hydrogen. The plant will use MyRechemical’s chemical conversion technology which allows the recovery of waste that cannot be mechanically recycled, or other types of unsortable dry waste. The carbon and hydrogen in the waste are converted via gasification into synthesis gas, which is used to produce low-carbon methanol and hydrogen.
Maire Tecnimont’s innovation and licensing company Stamicarbon has been selected as the licensor for a urea project in sub-Saharan Africa, its first license in the region. Stamicarbon will deliver the process design package for the front-end engineering and design for a 4,000 t/d urea melt and granulation plant. The urea melt plant with a pool reactor will use Stamicarbon’s MP Flash design, a melt concept with improved energy efficiency, entailing a significant reduction of steam consumption. The minimal equipment items result in a significant reduction of the footprint and the overall capital cost of the plant. Less equipment also allows for a reduction in maintenance costs and OPEX savings.
A round-up of current and proposed projects involving non-nitrogen synthesis gas derivatives, including methanol, hydrogen, synthetic/substitute natural gas (SNG) and gas- and coal-to-liquids (GTL/CTL) plants.
Chinese refinery output has been steadily falling this year as covid-related lockdowns impact upon the economy. Figures from the National Bureau of Statistics showed that refinery output fell to 13.8 million bbl/d in April – down 2% year on year – then took a sharp fall in May to 12.6 million bbl/d, more than 10% down on the same time in 2021, when output stood at 14.1 million bbl/d. May’s figure was 12.7 million bbl/d, a modest increase on April, but still 1.6 million bbl/d down compared to May 2021. Refining margins have also been hurt by high oil prices due to the Ukraine conflict, dropping close to zero or even negative according to industry estimates.
Researchers from Australia’s Monash University say that they have created a new generation of lithium-sulphur batteries which could provide a cheaper, cleaner and faster-charging energy storage solution that outlasts lithium-ion alternatives and is rechargeable hundreds of times without failing. The team has creating a new interlayer which allows for exceptionally fast lithium transfer, as well as an improvement in the performance and lifetime of the batteries.
The Jordan Phosphate Mines Company (JPMC) has signed a supply agreement with Germany’s LUMA-International Company.Under the terms of the agreement, JPMC will sell 850,000 t/a of phosphate rock to the German company at international market rates. The agreement was signed by JPMC CEO Abdulwahab Rawad and managing director of LUMA-International Ralf Keller, in the presence of JPMC Chairman Muhammad Thneibat. Thneibat expressed hope that the deal would open wider scopes of cooperation between the JPMC and German companies in the field of phosphate fertilizers, and Keller likewise said that his company was looking forward to more cooperation with the JPMC and new partnerships to produce phosphoric acid and phosphate fertilizers.
Gidara Energy has agreed with the Port of Rotterdam to develop a new waste to methanol facility in the Netherlands: Advanced Methanol Rotterdam (AMR). Gidara will duplicate its Advanced Methanol Amsterdam project as a template for AMR, using Gidara’s patented high temperature Winkler (HTW® ) technology, which converts nonrecyclable waste to renewable fuels. This technology has been used commercially in four other waste to syngas production facilities. AMR will convert around 180,000 t/a of non-recyclable waste into 90,000 t/a of methanol, while capturing all waste streams for use; CO2 will be captured and led to local greenhouses; bottom product residue will be used for cement production; and other streams like ammonia and salts will be sold and put to use as feed stock for other industries and road salt respectively, creating a fully circular concept. The facility is scheduled to start detail engineering and construction in the first half of 2023, when a permit is received, and start production of renewable methanol in 2025.
Casale has acquired Hong Kong-based Green Granulation Ltd (GGL), and its proprietary technologies for the design and construction of urea and calcium ammonium nitrate (CAN) granulation systems. Casale says that the takeover is part of a broader strategy aimed at strengthening its leading position in the nitrogen market by leveraging the widest integrated portfolio of efficient technologies, enabling the company to offer a ‘one stop shop’ for the entire production cycle of nitrogen-based fertilizers, from raw materials to final products. GGL’s addition to the Casale group includes the Cold Recycle Granulation process, an advanced fluidised bed technology designed to accept a lower concentration of urea feed melt (ca 96% urea and biuret), as well as a proprietary design for both granulator and scrubber, a team of experts and qualified technicians, and considerable experience in several industrial references. The CRG design has a horizontal layout, leading to lower structural costs and higher efficiency, as well as lower total investment costs and power consumption, lower power consumption and simplified operation, and higher operational flexibility in urea and CAN granulation.
