Honeywell UOP’s nViro Hydro process provides an alternative solution to conventional hydroprocessing waste treatment utilising a sulphur recovery unit and tail gas treating unit. Janet Ruettiger of Honeywell UOP discusses the benefits of nViro Hydro which include improved operational efficiency, creating a new revenue stream and reduced capital outlays, operating expenses and water use.
Gouda Refractories continues to upgrade its refractory solutions for the sulphur recovery industry as well as developing new superior products for installations operating at higher temperatures due to oxygen enrichment.
As plants move towards full unit control, Jochen Geiger of Ametek Process Instruments provides an overview of how the latest sulphur plant analysers are providing greater insight into sulphur plant operations.
A report on CRU’s annual Sulphur + Sulphuric Acid conference, held in New Orleans, USA, 6-8 November 2023.
Tecnimont, part of MAIRE’s Integrated E&C Solutions business unit, has signed a letter of award with ADNOC for the onshore processing plant of the Hail and Ghasha Development Project. The award was signed at ADIPEC, the world’s largest energy summit. The project aims to operate with net zero CO 2 emissions, in part due to the facility’s CO 2 carbon capture and recovery units, which will allow the capture and storage of CO 2 . The project will capture 1.5 million t/a of CO 2 , taking ADNOC’s committed carbon capture capacity to almost 4 million t/a. The company recently announced its decision to double its carbon capture capacity to 10 million t/a by 2030. The Hail and Ghasha CO 2 will be captured, transported onshore and stored underground, while low-carbon hydrogen will be produced to replace fuel gas and further reduce emissions, according to ADNOC. The project will also use power from nuclear power plants and renewable sources from the grid.
M. Rameshni and S. Santo of Rameshni & Associates Technology & Engineering (RATE USA) discuss some of the many solutions available to revamp sulphur plants to meet stricter environmental regulations with regard to SO2 and CO2 emissions. RATE technologies for the ultimate goal of achieving near zero SO2 emissions and World Bank requirements are also illustrated.
Following the completion of expansion work on the ultra-sour gas Shah field in May 2023, production has been ramped up. Occidental, which owns 40% of the Shah project and which operates the field in conjunction with ADONC Sour Gas, reported in July that it had achieved record output at Shah, with gross gas sales reaching 722 million scfd in Q2 2023 (equivalent to 1.1 billion scf/d of raw gas, which is 23% H2S and 10% CO 2 ). The expansion has taken processing capacity at Shah to 1.45 billion scf/d and forms part of the UAE’s plans to achieve gas self-sufficiency by the end of the decade. The expansion was conducted by Saipem, who were awarded a $510 million contract in 2021 to expand output from 1.3 billion scf/d to the current 1.45 billion scf/d. Work was completed two months ahead of schedule, according to Occidental.
With the aid of a rigorous kinetic model for TGU hydrogenation reactors, incorporating catalyst deactivation mechanisms, designers and operators can forecast the life expectancy of reactor catalyst beds.
CRU’s Sulphur + Sulphuric Acid 2023 Conference and Exhibition takes place at the Sheraton New Orleans, Louisiana, USA, 6-8 November. Take part in this leading annual forum for the global sulphur and sulphuric acid community to learn, connect and do business. Hear from industry leaders and subject experts from around world and across the industry.
Comprimo and Ametek now offer the Analyser Air Control Technology (2ACT) Solution to the industry in which the information for the SRU air control is available 6-7 minutes earlier with the installation of an acid gas feed analyser-based feed forward control. This improvement to conventional SRU combustion air control systems enables operating companies to control their assets closer to design capacity at higher recovery efficiency and with fewer unscheduled outages.
