The process mineralogy of potassium-rich shale from Chaoyang of Liaoning, China, was studied. Research results showed there are much less variety and smaller quantities in mineral compositions. Calculated mineral composition by means of chemical composition analysis combined with XRD, MLA, IR and TG-DSC analyses showed that main minerals with were Potassium-feldspar, muscovite, biotite and illite, and gangue minerals were quartz and small amounts of hematite. Potassium-rich minerals such as potassium-feldspar and muscovite contact smoothly with quartz respectively, and there was the direction arrangement among potassium-feldspar, quartz and muscovite in the shale. And quartz and hematite were main cement in the shale. The influences of the research results on the potassium extraction from potassium-rich shale were distinct.

Profile Reconstruction

The reconstruction of a lithological profile based on geophysical logs of chemical composition provided by geochemical gamma-gamma well logging probes has been increasingly used for geophysical interpretation. A chemical profile, analogous to the measurements mentioned above, can be determined based on measurements made with a portable X-ray fluorescence spectrometer (pXRF). This paper presents a methodology for determining the mineral composition of drilled, clastic, as well as clay-rich rocks on the basis of both inexpensive and timesaving pXRF measurements as well as models combining the results of chemical composition analysis with results of mineral composition analysis (XRD). The results of chemical composition analysis obtained with a portable XRF spectrometer were calibrated based on a detailed analysis produced with ICP-OES and ICP-MS methods. A significant advantage of the proposed method is the possibility to apply it with regard to drill cuttings as well as archival cores. However, considerable discrepancies in the results obtained were identified while comparing the results of chemical composition analysed directly on the core and milled material. The analysed material comprised Carboniferous rocks derived from three boreholes located in Poland: Kobylin-1 as well as Biesiekierz-1 and -2. It was possible to directly compare the lithological profile obtained based on measurements taken on drill cuttings with the results of the lithological interpretation of a geochemical probe log.

Abstract A column distillation has been operated for 42 years , Leaking often happens in top of tray part. it has been repaired by jacketing and patching. Meantime there are still some leaks and damages happens in top tray. Some research and repair action were conducted to avoid the same problem in the future and to know the recent condition of the column using fractography examination, Metallography examination, hardness test, chemical composition analysis, thickness and pundit and the result will be deriving us to the caused of the failure and to the impact of the used of patching and jacketing on material. The research results reveal any corrosion and the elements that have been uneven jacketing conditions only at the top of the destilation column. AbstrakColumn distilasi telah beroperasi selama 42 tahun, beberapa kali mengalami kebocoran di dinding tray bagian atas dan setiap kali repair dilakukan dengan jacketing dan patching. Pada saat ini masih ditemukan ada beberapa kerusakan/kebocoran juga pada tray atas, untuk itu perlu dilakukan penelitian untuk tindakan repair dan mengetahui kondisi terkini column melalui pemeriksaan fraktografi, metalografi, uji kekerasan, komposisi kimia, ketebalan dan pundit sehingga secara keseluruhan hasilnya dapat mengetahui penyebab kerusakan dan mengetahui pengaruh patching dan jacketing pada material. Hasil penelitian ditemukan adanya unsur korosi serta kondisi jacketing yang sudah merata pada bagian atas coulumn destilasi.
