REDUCING CO2 THROUGH AIR
LEAK DETECTION C
arbon dioxide is a gas essential in the production of many everyday products, including food and bever- ages as well as being a key raw material in the fertiliser industry.
However, these days, carbon dioxide hits the news headlines for all the wrong reasons. According to a report issued by the Royal College of Physicians several years ago, in 2013 the concentration of carbon dioxide in the atmosphere had increased by about 42 per cent over the levels before the industrial revolution, and the concentra- tion continues to rise. Carbon dioxide is one of the main gases causing the Earth to overheat.
Much is spoken about the CO2 emitted by vehicles in the automotive sector; however the main
culprit is energy and heat generation. In 2020 elec- tricity and heat production accounted for over 15
billion tonnes of CO2 emissions, with transportation in second place at just over seven billion tonnes. Ask most industrial companies why they have sought to reduce energy usage in recent years and fiscal reasoning would be top of the agenda for many firms. We have seen huge increases in the cost of electricity in recent years, especially in Europe as geopolitical and economic pressures bear down heavily on the price of oil and gas. However, another reason, high on the agenda of many fortune 500 companies is the desire to reduce their carbon footprint, ensuring we leave this planet in good order for our children and future generations.
When it comes to reducing energy use on a large industrial complex, low hanging fruit such as low energy light bulbs and movement sensors have already been initiated. The more difficult areas are associated with the production itself, elements that require elevated temperatures can be better insulated, as indeed can refrigerated areas, but mechanical machines themselves can prove difficult to improve in terms of efficiency without affecting production.
One element that is found on most manu- facturing sites is the need for compressed air. Pneumatics are a common theme and used in all sorts of industrial applications. To deliver the compressed air, a compressor or number of compressors are employed, and the resulting air
