The need to be able to collect and destroy in a cost-effective way so-called dilute non-condensable gases, DNGC has increased as the EU tightened the requirements on industry to use the best available technology to reduce sulfur emissions to air.
The way for the pulp mills to solve the problem with DNGC is to reduce the various emissions and collect them to a point, for example the recovery boiler, for combustion. But in order to be able to dimension a plant for this, the size of the flows and their composition must be known.
The concept for the gas measurements is based on a portable gas chromatograph being set up on site so that the weak gases can be quickly analyzed from different test points. According to EU Directive 2010/75 / EU, the requirements in the BAT conclusions must be met by 30 September 2018 and all mills must report how the requirements are complied with or how they plan to comply with them. The concept is based on a portable gas chromatograph being set up on site, so that the samples can be quickly taken out and analyzed.
RISE has developed methods for:
DNGC mapping - measures flows and to analyze the sulfur content in the pulp mills DNGC.
What is usually called DNCG contains a mixture of different sulfur-containing substances such as hydrogen sulphide, methylmercaptan, DMS and DMDS. The method of pulping to solve the problem with swelling gases is to pull the different emissions together and collect them to a point, such as the soda boiler, for combustion. However, in order to be able to dimension a plant for this, the size of the flows and their composition must be known. The concept is based on the fact that a portable gas chromatograph is set up at the site so that the DNCG can be quickly analyzed from different test points.
Gases in ventes from tanks and from landfill gas - analyzes the content of methane and other gases in aerations from tanks and collection points from landfills.
