Linde has developed a new adsorptive carbon dioxide removal process, called HISORP® CC, including but not limited to blue ammonia production. Based on a combination of mature technologies the process overcomes the drawbacks of traditional CO2 removal techniques and provides a carbon capture rate of greater than 99%. Thomas Ried discusses the pros and cons of different process configurations for CO2 removal and the benefits of the new technology.
Despite being an age-old industry, the phosphate sector remains vibrant and driven by a passionate commitment to leaving behind a sustainable world for future generations. Tibaut Theys, general manager of Prayon Technologies, explains how the industry, by implementing more efficient production processes and promoting responsible fertilizer usage, is working urgently to reduce CO2 emissions, as well as striving to minimise its environmental footprint.
The recovery of waste heat from Aurubis’ copper smelting operation in Hamburg is already helping to reduce global carbon emissions and has the potential to provide heat for up to 20,000 homes through the district heating network in Hamburg’s HafenCity. The energy for the network comes from waste heat that Aurubis recovers from their sulphuric acid plant, using unique Alfa Laval plate heat exchanger technology.
Previously, recuperative reforming has been mostly applied for capacity increase revamps, but nowadays it is a key enabler for efficient low carbon hydrogen and syngas production. Jan-Jaap Riegman of Technip Energies, Francesco Baratto of Casale and Stefan Gebert of Clariant discuss the benefits of recuperative reforming for reducing the carbon footprint of existing assets.
Highly efficient N2 O abatement technologies, coupled with the continually rising CO2 e price/ tonne are the driving forces behind nitric acid plant operators looking for increasingly sensitive and precise measurements of the N2 O mass emission. David Inward of Sick AG discusses new state-of-the-art emission monitoring technology which provides the measurements required.
The world’s most common syngas production method remains steam methane reforming, a process which has a substantial CO2 footprint as the necessary reaction heat is supplied by combustion of hydrocarbons. Topsoe’s eREACT™ technology allows for the first-of-its-kind electrification of the traditional SMR process. The reaction heat for eREACT™ is instead generated directly by (renewable) electricity, thereby eliminating the flue gas altogether. Having gone through scale-up from bench scale to industrially relevant pilot scale the technology is now ready for industrial application.
Fertilizer plant owners are installing highly efficient and reliable scrubbing equipment to satisfy increasingly strict emissions regulations globally. We highlight recent advances in scrubbing performance and technology.
CO2 emission abatement strategies have become increasingly important as the world strives to combat global climate change. Mahin Rameshni and Stephen Santo of Rameshni & Associates Technology & Engineering (RATE USA) discuss carbon capture options available for sulphur recovery units.
A review of the current slate of plans for green and blue ammonia production.
Sulphur is a relatively safe and inert solid. However, it has a number of unique physical and chemical properties which can give rise to hazards, particularly during transport and handling.
