Reducing emissions and at the same time increasing process efficiency – is it possible?

Process operators are continuously under pressure to either reduce their emissions to atmosphere or increase their process efficiency. Some people see these 2 factors as competing, but they don’t have to be. I think you can deliver both and in fact, it has been proven that plants which reduce their pollutants also increase their efficiencies and reduce waste – creating a win/win scenario for all.

Reducing emissions and at the same time increasing process efficiency – is it possible?Monitoring for process and not just emissions is a very worthwhile activity and the application specific benefits can include:

  • Increasing safety by monitoring of CO levels in coal mills and silos which contain potentially explosive products.
  • Reducing the use of Ammonia in SCR & SNCR plants by monitoring of NH3 pre and post plant to minimise ammonia usage and reduce emissions of other subsequently created pollutants which can cause clogging of plant systems and additional emission monitoring requirements. 
  • Reducing the use of Lime and by monitoring and controlling the use of lime in sulphur reduction plants (FGD), as is converted to Gypsum and reducing it as a potential pollutant.
  • Reducing operational costs (electricity and pressurised air usage) by monitoring of dust filter efficiencies in electrostatic precipitators and bag filters.
  • Maximising melting points, whilst minimising waste gas emissions by ensuring gas concentrations are at process expected levels across furnaces, boilers and other smelting processes.

For operators, understanding the nuances of how to achieve both emission reductions and process efficiencies can be difficult, especially considering the range of monitoring instruments available.

So, my top considerations to achieve both are:

  • Ensure you choose a supplier with proven experience in your sector who understands your process.
  • Select instruments which are proven, accurate and reliable and where appropriate certified.
  • Ensure the supplier has local and fully trained service centres holding spares.
  • Ask for customer references and case studies.
  • Verify the supplier can deliver you “added value” from their products and/ services.
  • Don’t just go for the lowest priced instruments, as in most cases you do get what you pay for.
