As environmental SO2 emission regulations become more stringent, tail gas treating options become limited. To potentially achieve lower opex and improved plot plan, utilising a biological desulphurisation process as an alternative to a conventional amine-based TGT unit is becoming of increased interest in the oil and gas industry. At the same time, demands for increased SRU capacity and reliability favour the use of medium and high-level oxygen enrichment.

This article explores the opportunities presented by Stamicarbon’s tertiary abatement technology for both existing and grassroots nitric acid plants to enhance sustainability and efficiency and discover the advantages of incorporating these technologies into a green fertilizer complex.

Honeywell UOP’s nViro Hydro process provides an alternative solution to conventional hydroprocessing waste treatment. Benefits include creating a new revenue stream and reduced capital outlays, operating expenses and water use.

RATE USA discusess some of the many solutions available to revamp sulphur plants to meet stricter environmental regulations with regard to SO2 and CO2 emissions.

Kazakhstan’s oil and condensate output increased by 7% from 1.79 million bbl/d to 1.92 million bbl/d in early June after sour gas reinjection operations resumed at the Kashagan offshore oil and gas development following a recent outage, according to the Kazkah Energy Ministry. Reinjection of sour gas into two wells resumed on 8th June, enabling operator the North Caspian Operating Company (NCOC) to boost oil and condensate production at a large artificial island in Kazakhstan’s Caspian Sea waters. Reinjection was paused on May 20th following the detection of sour gas during routine sampling and a subsequent integrity test. Kashagan normally produces about 300,000 barrels of oil per day. Kazakhstan expects Kashsgan to raise oil production this year to 18.2 million t/a from 12.7 million t/a in 2022.

Metso is launching an advanced sustainable battery black mass recycling process as part of its battery minerals technology offering, which covers concentration and hydrometallurgical processing as well as related services. Demand for battery minerals is increasing sharply with the ongoing transition to clean energy sources. An electric car battery weighs approximately 200 kg. Recycling of black mass from batteries with Metso’s process can reduce up to 60% of embedded carbon compared to use of virgin materials and enables the treatment of mechanically separated and shredded batteries for recovering battery raw materials like nickel, cobalt, and lithium, as well as manganese and copper.

Liquid fuels will be with us for decades to come, but refiners will be pushed to decarbonise their activities, via greater use of biofuels, and green/blue hydrogen use.

Evonik explores the development of catalyst reuse and how recycled hydroprocessing catalysts can be successfully applied in tail gas treating units to deliver cost and performance gains.

Sulphurnet discusses the importance of a whole life cycle cost analysis at the conceptual design phase when making investment decisions about new sulphur processing facilities.

SO2 breakthroughs remain an ever present threat to the successful operation of reductive, quenchamine-based tail gas clean-up units (TGUs). Optimized Gas Treating presents a case study which demonstrates how SulphurPro's detailed reaction kinetics and mass transfer rate model can be used to analyse integration techniques and mitigation methods.
