In Part 4 of this series on stripper efficiency issues, we continue to look at the causes of lower stripper efficiency with a discussion on the high delta-P range of liquid dividers.

This study introduces a new platinum-promoted honeycomb catalyst for sulphur dioxide oxidation, designed to enhance energy efficiency and reduce emissions in sulphuric acid production. Compared to conventional vanadium oxide based catalysts, the platinum-based catalyst demonstrates higher catalytic activity, lower ignition temperature, and significantly reduced toxicity.

Due to ever stricter legislation towards lower SO2 emissions, superior catalyst shape and composition has become ever more important. Jochen Willersinn of BASF SE explains how BASF’s high-performance catalyst O4-116 Quattro combines the benefits of an increased surface area with a superior caesium-promoted active phase composition enabling significantly lower ignition and operating temperatures and thus reducing SO2 emissions.

New concepts focused on the transfer and combination of existing sulphur and sulphuric acid technologies to support decarbonisation of the sulphuric acid industry are being investigated. In this article three research projects are discussed: sulphur dioxide depolarised electrolysis for green regeneration of spent acid, use of renewable heat and catalyst to the splitting process from sulphuric acid to SO2 for reduction of fossil fuel consumption, and sulphur as an energy vector.

The production of urea, a critical component in the fertilizer industry, involves highly corrosive environments, particularly in the high-pressure sections of the process. This necessitates the use of advanced materials that can withstand such aggressive conditions to ensure long life and efficiency of urea production plants. Alleima, Stamicarbon, Saipem and TOYO report on their advanced material and equipment solutions for the urea industry.

Toyo Engineering Corporation has developed two new digital solutions, MethaMaster™ and MethaDynamics™ , which enhance the operational efficiency of e-methanol production from variable renewable energy.

The 38th Nitrogen+Syngas Expoconference will take place in Barcelona, Spain, from 10-12 February 2025. Join us at this industry leading event featuring the most comprehensive agenda to date.

Syngas generation units (SGU) represent a large portion of the capital and operational expenditure of ammonia plants and are critical from a mechanical reliability standpoint. Related capex/opex optimisation and mitigation of possible operational problems are key targets for ammonia plant owners. Giovanni Manenti introduces NITROQUENCH® technology which focuses on these key targets for ammonia SGU.

Blue hydrogen has emerged as a crucial technology for decarbonisation as nations around the world work towards net-zero carbon targets. By decarbonising hydrogen production and exploring clean hydrogen sources we can fully harness the potential of hydrogen in the global energy transition. Johnson Matthey, Topsoe and Casale report on their strategies and advanced technical solutions for large scale blue hydrogen production.
