A comprehensive method to assess the technical condition of the pressure equipment of installation operated in the chemical and petrochemical industry, with the use of acoustic emission signal analysis, structure stress field and the degradation st The algorithm for the assessment of the technical condition of pressure equipment of chemical and petrochemical installations, subjected to the long-term operation, allows to determine the damage degree of the material and allows to predict the further development of degradation processes in a function of time. The proposed approach to the problem of safe operation of devices is fundamentally different from the solutions which are currently used in industrial practice. Currently, the supervision of these objects is based mainly on standard non-destructive testing methods. The main limitation of used methods is the lack of the possibility of both examining the object in its entire volume and testing the device in working conditions. Developed algorithm allows to effectively solve current problems in the diagnosis of chemical installations related to the assessment of their technical condition and determination of the conditions for further operation in real time. The algorithm is particularly recommended for monitoring devices in which adverse damages occur due to the long-term operation.

Due to the rising emission of methane and its extensive contribution to the greenhouse effect, the reduction of CH4 emissions from low-caloric anthropogenic sources is currently a vital importance. The main sources of the methane emission are: exploitation of oil pools, coal mining, pas power stations, landfills, agriculture and biomass. The most popular method of the reduction of methane is its catalytic combustion. Unfortunately, this method has few limitations associated mainly with hard activation of the C-H bond in CH4 and low concentrations of methane in the emitted gases. The catalytic oxidation of methane is limited also by the very large airflows (of order 105 m3/min), passing through the catalyst bed during the process. There is still a lack on the market of a technological solution based on total catalytic combustion of CH4 in the economically reasonable low-temperature window, i.e. below 400 °C. The most popular method among the methods limiting the emission of methane to the atmosphere is the one based on its catalytic combustion. However, this procedure has disadvantages, mainly due to the high activation energy of methane molecules and also because of the low concentration of methane emitted from anthropogenic sources. There is no technology allowing effectively combusting of methane with the concentration of 1-2 % and in the economically justified temperatures, i.e. lower than 400 °C. The fundamental advantages of offered solutions are: - method for preparing catalysts that ensures the repeatability of the parameters and high efficiency in the reactions of methane combustion, - increased both the activity and the thermal stability of the catalysts in comparison with other systems described in the literature, - possibility of using the catalysts in the total oxidation of methane emitted from the low-caloric sources at temperatures below 400 °C.
