TRS system

TRS system

The TRS system is an innovative solution for analysing total reduced sulphur compounds (TRS) in emission gases. It enables accurate measurement and continuous monitoring of sulphur compounds such as hydrogen sulphide (H₂S), mercaptans and sulphur dioxide (SO₂). The system is designed to eliminate the need for chemicals such as phosphoric acid and hydrogen peroxide, making it both safer and more cost-effective.

The TRS system is designed to eliminate traditional challenges of classical analytical systems that require the use of chemicals to stabilise and convert sulphur compounds. Instead, this system uses an innovative low-scrubbing gas cooler, which means that sulphur dioxide (SO₂) does not precipitate into condensate. The chemically treated granulate selectively absorbs SO₂ without affecting other TRS gases.

When analysed, H₂S and mercaptans are converted to SO₂, which is then measured separately. The TRS value is calculated as the sum of SO₂, H₂S and other reduced sulphur compounds. The system is equipped to handle measurement ranges from 0-10 ppm up to 0-1000 ppm, making it adaptable to different industrial needs.

The technical advantages of the system include:

  • Fast response time: Less than 60 seconds (excluding preheated hose).
  • Minimal maintenance requirements: Few moving parts and low consumption of spare parts.
  • Chemical free: Elimination of phosphoric acid and hydrogen peroxide, reducing handling risks and costs.
  • Compact design: Requires a small footprint and is easy to integrate into existing facilities.

The TRS system is designed to ensure reliability and dependability. During commissioning, detailed analyses of response times and critical flows are performed to optimise performance. This makes it an optimal solution for pulp mills, chemical industries and other operations with a need for efficient emission control.

Features and benefits

  • Advanced gas cooler: Prevents SO₂ from being scrubbed off in condensate, ensuring accurate measurement.
  • High flexibilityAdaptable measuring range for different applications.
  • Chemical-free system: Eliminates the need for phosphoric acid and hydrogen peroxide, improving safety and reducing operating costs.
  • Fast response time: For 60 seconds to ensure fast and accurate measurements.
  • Low maintenance requirements: Few moving parts and spares, reducing the need for regular servicing.

Applications

  • Pulp mill: Continuous monitoring of TRS emissions during pulp production.
  • Chemical industry: Control and analysis of sulphur compounds in processes.
  • Industrial emission streams: Effective monitoring of emissions to ensure compliance with environmental regulations.
