    Badania laboratoryjne demulgacji rop naftowych metodą termochemiczną
    (2007) Jewulski, Jan; Zagrajczuk, Danuta
    The results of laboratory experiments on the efficiency of various surfactants in the process of thermochemical demulsification of selected oils from the Polish oil fields are presented in the paper. The correct selection of a demulsifier on the basis of individual investigations shall enable best decomposition of the oil-water emulsion. Laboratory tests were carried out at 4 various temperatures 40, 50, 60 and 70 degrees of Celsius for various times of sedimentation of the emulsion. Some of the results are presented in tables or in a graphic form. On this basis the best demulsifiers could be chosen for the given types of oil.

    Badania laboratoryjne regeneracji glikolu trójetylenowego (TEG) z wykorzystaniem promieniowania mikrofalowego
    (2007) Wójcikowski, Maciej
    A brief analysis of the state of glycol revitalization in the Polish industry is given in the paper. The author presented advantages of microwave heating, indicating the possibility of using this method for TEG revitalization. A laboratory stand was made with the main components: a microwave boiler RM 800 produced by 'Plazmatronika' in Wrocław, Poland, and a microprocessor apparatus for volumetric measuring water with Karl Fischer reagent DL 39 produced by the Swiss Mettler Toledo. The author described the obtained results and briefly analyzed them indicating very advantageous influence of vaccum in the process of glycol tri-ethylene revitalization with the use of microwave radiation.

    Pęcznienie mineralno-chemiczno-organicznych mieszanek gruntowych
    (2007) Stryczek, Stanisław; Gonet, Andrzej; Rzyczniak, Mirosław; Czekaj, Lucyna
    The results of studies of determining liability to swelling of chemically treated mixtures of waste drilling mud with organic and ground admixtures are presented in the paper. The investigations were carried out as a part of a project on methods of drilling waste processing and managing. In the course of the analyses, the following parameters were determined: natural humidity, swelling humidity, swelling indices, degrees of swelling, mineral-chemical--organic ground mixtures. The trends of changes of swelling indices, depending on the composition of the mixtures, were also determined.

    Wpływ temperatury na właściwości technologiczne zaczynów uszczelniających stosowanych do prac geoinżynieryjnych
    (2007) Stryczek, Stanisław; Gonet, Andrzej; Wiśniowski, Rafał
    Sealing slurry should meet a number of requirements resulting from the specific conditions encountered in the injection wells during rock mass sealing and reinforcing operations. Sealing slurries used in the geoengineering works should provide proper course of injection procedures and be resistant to the reservoir conditions. Owing to the atmospheric conditions in which injection is performed (high amplitude of temperature), this factor should be accounted for when working out recipes. The results of investigations of the influence of temperature (5, 10, 20 degrees of Celsius) on the technological properties of sealing slurry based on the metallurgical cement CEM III/B - 32.5 and CEM III/C - 32.5 are presented in the paper.
