SEM: Deposits in systems of industrial facilities
Because of electrochemical processes, mineralized waters or temperature and also pressure variations in industrial facilities, corrosive processes can be initiated. These lead to the formation of minerals in the medium. The analysis of those new mineral formations contributes to the diagnosis of this processes and helps prevent acute malfunctioning in the operating procedure.
Microscopy: Analytics of fibers in industrial-scale processes
In industrial-scale installations sometimes malfunctions of the normal operating procedure occur, due to unpredictable events like the blockage of filter in vents or pipelines. Quite often, fibers of all sorts, length and source are the cause of this events.
Microscopy: Microscopic analysis of construction material
Within the context of material analysis, LAOP provides microscopic studies in the field of building materials. Here light optical, electron optical and microchemical analyses methods are deployed. This is exemplified by a project together with the Malaysian cement producer CMS...
Within the context of renaturation of mining used areas different soil improvement concepts were prepared. One of it is the conditioning of iron hydroxide slurry (IHS) by power plant cinders within a pilot project. These conditioned IHS shall be applied as pure soil or as soil mixed with dump material.
Geology: Seam anomaly in the open-pit mine Welzow-Süd
The seam anomaly in the open-pit mine Welzow-Süd is an elongated structure, which differs from the normal-facies seam build-up. Further occur doubling of seam parts due to thrust faults, distribution gaps of the interburden 2, the local occurrence of the horizon 11 as well as...
Microscopy: Sediment petrographic investigation of the Meuro Formation
In the course of the master thesis “Lithofacies classification of sediments of the Meuro Formation in the open lignite pit Nochten” by Patrick Bieder, curated by LEAG, sediment petrographic investigation was done on 10 chosen samples.
Environment: Disposals by the wayside
The environment agency delegated us with the analysis of an illegal disposal at the outskirts of a forest trail. After realized sampling, light optical and electron optical investigations can be realized contemporary to enable rapidly a hazard evaluation of the substance.
Archeology The "Venus vom Hohle Fels": The Birth of Art
In a cave at the Swabian Alps archeologists of Tübingen discovered an over 35.000 year old fertility symbol – the oldest figural portrayal ever of a human.
Environment: Scanning Electron Microscopy of dust precipitations
Within the context of an examination of the precipitation of dust at the months January to June, we were retained to characterize immission samples, but also contemplable emission sources, by scanning electron microscopy.
Microscopy Investigation of corrosion in plant engineering and construction
At power plant processes the formation of deposit within the scope of the flue gas line occurs at times, especially in the cyclones for fly ash separation. These deposits have a disturbing effect on normal operation and therefore are object of further investigation.
Microscopy: Study of clinker formation in power plant processes
At power plant processes the clinker formation within the scope of the flue gas line occurs at times, especially in the cyclones for fly ash separation. Such deposits have a disturbing effect on normal operation and therefore are object of further investigation.
Geology: Survey of geological structures using GPS
To get the correlation of the location of horizons, sections and section lines as accurate as possible we utilize the possibility to determine geographical coordinates by means of satellite-based survey.
Environment: Maceral analysis and microscopic evaluation of peat samples
The maceral analysis is a micro-petrographic determination method. The investigation of peat, as well as brown coal and lignites, is carried out according to microscopic respectively visual characterized basic components, the macerals.
Geology: Sampling, chemical and petrographical evaluation of the coal seam sequence at two profiles in the surface mine Vereinigtes Schleenhain
In the course of calibration of the SOLAS-device at the power plant Lippendorf, our company got the assignment, by Vattenfall (power plant) and MIBRAG (mine), to take geological samples from the main- and lower-seam-complex.
Geology: Coal quality treatments at the Lausitz lignite surface mine Nochten
For providing consistent, high-class feedstock for the customers of the Nochten mine, detailed knowledge of quality data is necessary already by developing of the mining strategy. Mined from the 1st and 2nd Lausitz seam is lignite for either power station or refinement with different primary resource qualities.
Archeology: Faciel correlation of archeological findings to the oil shale layers of the Kimmeridge Clay at the south coast of England
Archeological findings of armlets and other objects in the western Switzerland produced questions to the origin of the artifacts and the trade relationships in the Late Bronze and Early Iron Age.
Geology: Mapping of sulfur content at the surface mine Nochten to designate lignite for refinement
Beside the parameter ash the content of sulfur is of significant importance for producing pulverized lignite, lignite briquette and fluidized bed lignite. These products run through processes where no smoke desulfurization is envisaged.
Geology: Mapping of poorly accessible areas in lignite surface mines
Geological structures like the “Nochtener graben” or troughs make it harder to gain access to some areas of the 2nd Lausitz seam at the surface mine Nochten. To get a representative outcrop frequency we have been instructed to find a possibility for getting access to lignite in depressions.
Microscopy: QMAT – Quantitative Micropetrographic Analysis with evaluation of Textite
QMAT is a coal-petrologic investigation method for qualitative statements about refinement properties. Studied are constituents (microlithotypes) of lignite.
Geology: Study of selected section areas of the exploratory drilling in the forefield of the surface mine Jänschwalde
To clarify geological issues, geochemical point of views can provide helpful arguments. At this project we have been instructed to run an element screening at a drill core using the XRF handheld device and perform an evaluation of the element content.
Microscopy: Xylite classification
Important for the construction and dimensioning of mills, which for example are installed in generating stations and refinement plants to crush coal, is the content of varieties of fossil wood in the lignite seam.
For evaluating the xylite content in lignite two methods can be used.
Microscopy: Cuticular analysis of lignites of the Lausitz district
The analysis of cuticles answers the purpose of facies classification in lignite and carboniferous clastic sediments. It uses in lignite enclosed leaf fragments, whose cuticles are presented in fragments (Cuticulae dispersae) in the preparation.
