Chemical Analysis Services
We are realising gas and particle analysis on site or also in our chemistry laboratory at our head office in Stadthagen.
Continuous measuring instruments are available for the gas analysis of a large number of components. The concentrations of other gas ingredients will be determined by means of sample taking on site with subsequent evaluation in the laboratory or, if possible, directly at the place of measurement. We are amongst others realising the following measurements:
- gas composition regarding O2, CO2 and humidity
- acid crude gases such as HCl, HF, SO2
- NOX
- hydrocarbon
- mercury
Further gas ingredients such as heavy metals or dioxins/furanes will be analysed in external laboratories after sample taking by us.
The particle analysis realised in large parts in our chemistry laboratory but also on site, comprise amongst others
- the mechanical features of particles such as apparent density, grain size, flow behaviour
- the chemical composition particularly for the determination of utilisation of additive powders (residual calcium content, residual sodium carbonate content, chloride, fluoride, sulphate, sulphite). We are also offering to our customers the possibility of an on-site analysis.
- Combustion-related features, i.a. hot bearing test
- Examinations by means of optical microscope
If required we will arrange for complete analysis of dust samples with regard to the chemical composition in external laboratories.
In addition to basic investigations, we determine for our customers the most advantageous process engineering plant design and the expected additive consumption in compliance with the required residual pollutant gas content in the clean gas in series of measurements over several days in accordance with the respective task in relation to dry temperature, dew point, HCl and SO content.
In addition, demonstration filters in various sizes are available for on-site use. These filters are operated in automatic mode around the clock. Important measurement data are continuously measured and recorded and evaluated by modern recording systems. Due to a multitude of practical experiences, an implementation of the obtained test results on the design of a large-scale plant is secured and possible without restrictions.
Measurements and test series for fundamental investigations or optimisation measures on large-scale plants complement our activities in the R&D field. In addition to measures to optimise operating costs, e.g. with regard to energy consumption or the use of additives, the focus here is often on comparative studies of different needle felt qualities. It is possible to measure individual flat tubes comparatively with regard to throughput performance over a longer period of time. Further investigations can then be carried out in our flat hose test laboratory after the test bags have been removed.
We carry out R&D investigations for our customers on a task-related basis as well as within the scope of fundamental investigations for our own further developments.
