Daniel R. Egger of Sulzer Chemtech Ltd discusses mist elimination challenges in strong sulphuric acid applications and presents the unique Sulzer KnitMesh XCOAT™ mist eliminator as an ideal solution for corrosive services such as in sulphuric acid drying towers.
At the organisation’s first face to face meeting since covid, in Vienna in early October, OPEC+ ministers agreed to cut global oil supplies by 2 million bbl/d in November. OPEC+ is a group of 24 oil-producing nations, made up of the 14 members of the Organisation of Petroleum Exporting Countries (OPEC), and 10 other non-OPEC members, including Russia. In a statement, the group said the decision to cut production was made “in light of the uncertainty that surrounds the global economic and oil market outlooks.”
Industry focus on technologies to reduce the carbon intensity of ammonia and methanol production has been intensifying. In this article thyssenkrupp Uhde, Proton Ventures, Toyo Engineering Corporation, Stamicarbon, BD Energy Systems and KBR report on some of their latest technology developments towards decarbonisation.
Refractories are heat resistant materials used in high temperature processes to protect industrial equipment such as utility boilers, heaters, and ammonia primary and secondary reformers against heat and chemical attack. In this article Hasan Akbari of Kermanshah petrochemical Industrial company (KPIC) reports on experiences of different stages of refractory casting in the secondary reformer of an ammonia plant, located in Kermanshah province of Iran (KPIC – Phase II). The pouring operation was carried out in three stages and each section was cast nonstop for a period of three days in total.
Fischer-Tropsch technology has long offered alternative production routes to synthetic fuels, but has struggled to make a use case outside of some niche applications. Could the greening of the chemical industry offer another way forward for the technology?
Catalysts are of crucial importance in a number of chemical processes and hence, their quality has a direct impact on the efficiency and operating costs of chemical plants. This refers especially to ammonia production, since this process is energy-consuming.
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.
Optimisation of the nitric acid process depends on good process visualisation tailored to the specific process parameters of the plant, improvements in combustion efficiency, reduction of N2 O emissions and the optimal use of platinum group metals.
Most nitric acid is used for production of fertilizer nitrates and ammonium nitrate explosives, but it is also used in polyamides, polyurethanes and aniline dyes as well as a number of industrial processes including ore treatment. High ammonia prices have pushed nitric acid prices to record levels this year, but growth predictions remain robust.
