As Comprimo celebrates its 100th anniversary, we explore the group’s history from its earliest days in the Netherlands in the 1920s to its current status as a global leader in gas treatment and sulphur recovery technology.

Ganank Srivastava of Bryan Research & Engineering examines ways to reduce carbon footprint in sour gas facilities.

Though production, particularly from sour gas in Alberta, has declined, Canada remains the world’s second largest exporter of sulphur.

The Aecometric 3rd generation burner was developed, installed and commissioned for an SRU incinerator with increased stringent demands to reduce NOx emission and lower energy consumption. Mason Lee of Aecometric Corporation reports on the new burner design and performance. The emission test results show a significant improvement in addressing these environmental concerns to achieve low NOx (<50 mg/m3 ) combustion and minimise CO (<200 mg/m3 ) emissions.

Sulphur Experts outline the steps required to determine optimised SRU incinerator operating conditions. Although a proper determination of the ideal SRU incinerator operating conditions for any given facility is complicated by a combination of inconsistent permitting standards and poor understanding of the role of the SRU incinerator, the payoff for incinerator optimisation is a significant decrease in natural gas usage with corresponding savings in operating costs, a decrease in CO2 emissions, and a simultaneous reduction in NOx and SO3 emissions.

CRU and UniverSUL Consulting, together with the event host, ADNOC, are delighted to welcome you back for MEScon 2024 at the Conrad Abu Dhabi, Etihad Towers from 20 to 23 May 2024.

The implementation of WSA technology to recover sulphur as sulphuric acid from lean sulphurous off-gases offers significant environmental benefits. These include waste reduction, resource efficiency and reduced overall CO2 e footprint, while also producing profitable sulphuric acid. By embracing such practices, industries can ensure improved or better consumption and production patterns and foster a more sustainable and responsible future. J. Feddersen and S. S. Johansson of Topsoe illustrate these benefits using three distinct industrial applications where WSA technology provides a smarter way to treat sulphurous off-gases. It is not only waste stream management in the three cases, but also reduced transportation of chemicals, reduced opex and reduced CO2 e footprint.

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.

In the final part of this two-part article, Michael Huffmaster , Consultant, presents case study results using a discrete reactor model incorporating heat, mass transfer, and activation reaction kinetics to assess the impacts of these variables on in-bed temperature profile and activation effectiveness. Tailoring gas rate, composition, and temperature progression can achieve in-bed exotherms which improve CoMo catalyst activation effectiveness for low temperature tail gas units.

We report on the key highlights of the annual SulGas® conference, organised by Three Ten Initiative Technologies LLP,, which took place in Mumbai, India, from January 31 to February 2, 2024.
