The Valkyrie™ process was first introduced as a reborn version of redox technology for treating H2 S in natural gas processing.In this article Streamline Innovations Inc. highlights some of the new developments and successful applications of the Valkyrie process and its redox technology, in both gas and water streams.
M. Rameshni and S. Santo of RATE discuss different sour water stripping gas processing options, depending on contaminants in the sour water streams and site-specific requirements.
New low-cost metal oxide solid scavengers for hydrogen sulphide (H2 S) removal from wet and dry natural gas have been developed and deployed at commercial scale. The desulphurisation process uses a proprietary sorbent chemistry to achieve a high sulphur capacity and removal efficiency. G. Alptekin, F. Kugler and M. Schaefer of SulfaTrap LLC describe the new technology and its performance.
Buss ChemTech AG offers the international phosphate industry a robust solution to create added-value products from fluorosilicic acid (FSA). Thomas Dahlke, the head of the company’s process engineering department, and Emre Sen, sales manager for fluorine technologies, explain how this can be done in a sustainable manner.
BHP has finally given the go ahead for stage one of its Jansen potash mine project in Saskatchewan, Canada.
While the past couple of years have seen considerable excitement and momentum concerning the use of blue/green ammonia as a fuel, an announcement in August by Maersk, the largest shipping company in the world, has served once again as a useful reminder that ammonia is not the only candidate molecule. Maersk said on August 24th that it is ordering eight methanol powered vessels from South Korea’s Hyundai Heavy Industries at a total cost of $1.4 billion. Each giant ship will have the capacity to carry 16,000 twenty-foot [container] equivalent units (TEUs).
OCI subsidiary Fertiglobe says that it has partnered with the Abu Dhabi National Oil Company (ADNOC), to enable the sale by ADNOC of the first cargo of blue ammonia to Itochu in Japan, for use in fertilizer production. Fertiglobe, a 58% − 42% partnership between OCI and ADNOC respectively, will produce the blue ammonia at its Fertil plant at Ruwais in Abu Dhabi for delivery to ADNOC’s customers in Japan. This represent the first production milestone of a planned scale-up of blue ammonia production capabilities in Abu Dhabi, which is expected to include a low-cost debottlenecking program at Fertil. In addition, it was announced in June that Fertiglobe will join ADNOC and sovereign wealth fund ADQ as a partner in a new world-scale 1.0 million t/a blue ammonia project at Ta’Ziz in Ruwais, subject to regulatory approvals. The design contract for this project has been awarded, with a final investment decision expected in 2022 and start-up targeted for 2025. A feasibility study was also agreed in July betweenh the state-owned Japan Oil, Gas and Metals National Corp. (Jogmec), Inpex and JERA as well as ADNOC to explore the possibility of producing 1.0 million t/a of blue ammonia in Abu Dhabi and transporting it to Japan.
Arun Murugan and Mike Antony of FITIRI and Venkat Pattabathula of SVP Chemical Plant Services discuss the COORS Analytics system for more accurate prediction of the performance of a CO 2 removal system.
India’s power and renewable energy minister RK Singh has placed draft plans before the cabinet for the country’s refining and fertilizer sectors to switch to renewable ‘green’ hydrogen feeds. Other energy intensive sectors such as steel and transport are likely to follow. The policy suggests that refiners must have 10% of their hydrogen consumption generated from renewable electricity by the end of financial year 2023-24, rising to 25% by 2030. The comparable figures for ammonia/urea production are 5% and 20%, respectively. India is pursuing some of the world’s most ambitious renewable energy targets of 175 GW of renewable energy capacity by the end of 2022 and 450 GW by 2030.
Tightening regulations and growing global competition are increasing the pressure felt by sulphuric acid plant operators to reduce emissions and improve energy output. Conservation of energy is a continuous focus for operators, and environmental communities have grown more vocal in their desire for greater emissions oversight. In this article, DuPont Clean Technologies examines simple, tried, and true tactics, as well as new products and designs that can be incorporated into existing plants to address operating efficiency and emissions and to help to prolong the life of the plant.
