Determination of total mercury in raw petrol using cold vapour atomic absorption spectrometry
PublicationPresence of different forms of mercury in petroleum based products may impair the proper operation of the equipment or led to poisoning of automotive catalysts. However much more important problem is environmental pollution with mercury emitted from different types of fossil fuels. Although the average mercury concentration in petroleum based products (automotive fuels) is on the level around 1 ppb, taking into account annual...

Detection of petroleum products using optical coherence tomography
PublicationIn this work, we present a novel method developed for the analysis of the properties of thin layers for detecting petroleum products on a water surface using a commercially available optical coherence tomography (OCT) system. The spectral density analysis of the signal from a spectroscopic OCT (S-OCT) enables us to perform the precision calculation of the thin layer thickness and other properties like homogeneity, and dispersion,...

Liquid-liquid separation in petroleum production: ultrasonic characterization of emulsion stability.
PublicationPrzedstawiono nowe urządzenie pozwalające monitorować rozdział emulsji za pomocą ultradźwięków. Wykonano kalibrację, dzięki której można sygnał szybkości rozchodzenia się dźwięków przekształcać na stężenie fazy wewnętrznej emulsji oraz otrzymywać wykres rozdziału faz w czasie. Wyniki otrzymano dla modelowej emulsji typu O/W, w której fazę olejową stanowił bitumen oraz dla emulsji W/O, gdzie fazą olejową była ropa naftowa
