When candle filter mist eliminators installed in the absorption towers in sulphuric acid plants are not sufficiently wet, problems can occur such as free SO3 at the stack, NOx issues and emission non-compliance. Craig Cassells of Begg Cousland Envirotec discusses how these problems can be overcome by the installation of an annular wetting ring solution.
Safety in sulphuric acid plants is a well-known and widely discussed topic. Industry turnover is a reality, and keeping new employees informed of hydrogen safety procedures is key to keeping plants fully operational and incident free. Walter Weiss of Elessent Clean Technologies discusses the steps facilities need to take to prevent hydrogen incidents.
Lithium miner Ioneer Ltd has signed a non-binding Memorandum of Understanding with Shell Canada Energy for the supply of sulphur to Ioneer for its Rhyolite Ridge lithium-boron project in Esmeralda County, Nevada. Ionner said in a statement that “securing the supply of key reagents for ore processing is an important step along the critical pathway to developing the Rhyolite Ridge project”. Under the memorandum, Ioneer will purchase up to 500,000 t/a of high-quality sulphur from Shell, which would fulfil the estimated annual sulphur requirement for the Project.
CRU Events will host the 2023 Nitrogen + Syngas conference and exhibition at the Hyatt Regency Barcelona Tower in Barcelona, 6-8 March.
Cansu Doganay of Lux Research takes a look at the current technology landscape for methane pyrolysis for producing low-carbon hydrogen from natural gas.
A review of the current slate of plans for green and blue ammonia production.
Due to the inherent nature of the renewable power, sizing eSyngas plants powered with renewable energy brings complexity normally not faced by natural gas-based facilities. In this article, Dr Raimon Marin and Dr Solomos Georgiou of AFRY discuss the application of AFRY’s state-of-the-art modelling tool to optimise the size and production of a green hydrogen system and a green ammonia plant based on given renewable power profiles and their associated variability (e.g., hourly, daily, seasonally, and annually).
Stamicarbon has won a contract for a large-scale urea project in China. The urea plant, with a production capacity of 3,800 t/d, will be the largest ever licensed by Stamicarbon in the country. The customer, the plant’s location and the value of the contract have not been disclosed.
Fulcrum BioEnergy says that it has successfully produced low-carbon synthetic crude oil using landfill waste as a feedstock at its Sierra BioFuels Plant, the world’s first commercial-scale landfill waste-to-fuels plant. Located outside of Reno, Nevada, Sierra will produce approximately 11 million gallons of renewable, low-carbon transportation fuels each year from approximately 175,000 t/a of landfill waste.
Air Liquide presents the results of an internal study to identify preferred natural gas-based plant configurations at a methanol capacity of 250 t/d. Delivering small capacity plants requires a focus on the total cost of ownership (TCO) for the economics to be successful, in addition to the CO 2 footprint of the operation. As found by this study, SMR concepts are naturally power balanced for standalone greenfield operations and show no particular advantage for power import in a brownfield setting. POX and ATR cases are greatly improved and even advantaged in a brownfield setting compared to SMR when shifting from power balance to power import cases.
