Good vibrations (for continuous pollutant measurement anyway)

Envirotec Magazine

Its high-energy UV radiation in particular is strongly absorbed by all materials and triggers photochemical reactions of compounds present in the air. A well-known example is the formation of ground-level ozone when UV light hits nitrogen oxides. Sunlight has a major influence on chemical processes.

The quest for cleaner air

Envirotec Magazine

The industrial revolution – despite its many benefits – sounded a death knell for air quality, increasing coal-generated smog levels 50-fold in many large cities. Air pollution does not just cause health problems, it also presents a significant social and economic burden. trillion, equivalent to 6.1

sources include vehicle emissions, coal-burning power plants, industrial emissions, and burning agricultural waste. The report also noted that many of these cities lack ground-level monitoring of PM2.5, At the same time, Beijing has expanded its monitoring system from 35 stations in 2013 to over 1000 in 2019.

We are betting the bank on hydrogen. But are we ready for it?

Envirotec Magazine

Green hydrogen holds many promises: it can serve as a ‘battery’ for energy storage, it can be used in the chemical industry, and its only emission will be water vapour. Researchers of the University of Groningen discuss the challenges it currently presents. To make this happen, you need to add some energy.

Ammonia tuning: Developing catalysts for cleaner fuels

Envirotec Magazine

This four-year project is funded by an EPSRC grant and supported by the industrial partner Eminox. The project is led by Bill Nimmo, Professor of Energy Engineering and Sustainability, with PhD student Madhumitha Rajendran. Ammonia presents a number of challenges as a fuel for engine combustion.

Measuring NOx in combustion

Envirotec Magazine

NOx gases are mostly produced by the combustion of hydrocarbons in vehicles and engines, as well as industrial processes such as power generation and cement manufacture. NO2 is generated by industrial processes including cement manufacture. Typically, at Signal Group, the flows of ozone and sample are set in a ratio of 10:1.
