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.
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.
When candle filter mist eliminators installed in the absorption towers in sulphuric acid plants are not sufficiently wet, problems can occur such as free SO3 at the stack, NOx issues and emission non-compliance. Begg Cousland Envirotec discusses how these problems can be overcome by the installation of an annular wetting ring solution.
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.
The refurbishment and modernisation of fertilizer plants offers the opportunity to reduce operating costs, raise production capacity, improve energy efficiency and cut emissions.
The trend for multicomponent analysis of emissions from sulphur recovery units is becoming more widespread. David Inward of Sick reports on a recent field trial to test the suitability of a hot extractive infra-red analyser for this application. In addition to reliably measuring and reporting emissions to air, the analyser is also capable of contributing to reducing overall tail gas emissions by supporting enhanced optimisation of the thermal oxidiser.
