Despite increased use of biomass of soybean in the Brazilian energy matrix, petroleum products remain the most economically viable.
A traditional petroleum-based epoxy matrix, bisphenol A diglycidyl ether (BAGDE), was also used for comparison and to precise the functionality of synthetized amines.
The separate use of size exclusion chromatography and adsorption chromatography during the sample preparation step does not allow selective isolation of PAHs from the hydrocarbon matrix of petroleum products, thus precluding trace analysis of PAHs in these materials.
After an investigation into HSE training performance in petroleum and petrochemical enterprises, HSE training matrices templates for 239 grassroots posts involving 22 primary petroleum and petrochemical disciplines were developed based on the technical requirements of HSE training matrices templates and the studies of template development processes and technical methods at grassroots level.
SEC has found numerous uses for sample preparation in the determination of many low-molecular-weight contaminants such as pesticides, drug residues, and PAHs in food, petroleum products, the environment, and other matrices [ 5– 7].
Heavy oil trapped in fractured carbonate reservoirs possesses a great challenge to the petroleum industry due to high oil viscosity, low matrix permeability, and unfavorable wettability of the matrix.
The GC × GC-FID/-SCD settings were optimized for ppm analysis of sulfur compounds in olefin-rich (ethylene- and propylene-rich) hydrocarbon matrices produced by steam cracking of petroleum feedstocks.
In case of a petroleum production system, this may lead to permeability damage of the reservoir pore matrix, blocking production tubing, surface flow lines and fouling of surface equipment.
Fully bio-based, partially bio-based and petroleum based composites are compared to investigate the effect of different polymer matrices on thermal properties of composites.
After analyzing the HSE training performance in petroleum and petrochemical enterprises, and combing the technical requirements for developing HSE training matrices, the following development process of HSE training matrices for grassroots units was proposed (Fig. 1).
The redundant information and measuring errors in the pre-determined petroleum fraction samples are eliminated through the procedure of calculating the basis fractions with non-negative matrix factorization (NMF) algorithm, meanwhile the scale of the feedstock database is highly decreased.
