In the oil industry, the issue of controlling paraffin deposits remains relevant today. The most common way in the Perm Krai to remove paraffin is to lower the scrapers into the well.  This method is the main in the fight against paraffin deposits, but does not provide absolute protection. The least costly way to control paraffin is to use flushing with hot oil or water, but it does not always ...

The article is devoted to the study of influence asphalt-resin-paraffin deposits on temperature oil saturation by paraffin. As a result analysis and generalization published works statistical information, empirical dependences paraffin content asphaltenes, resins paraffin, were obtained, which identified for conditions Ural-Volga region Kazakhstan

The article deals with the process of “waxing” pipes and choice effective measures to prevent these negative phenomena. To assess nature asphalt-resin-paraffin deposits (ARPD) select a further investigation scheme, X-ray Spectral analysis was used. It is shown, that ARPD complex system structured by resinous-asphaltene substances paraffin-naphthenic or paraffin-aromatic hydrocarbons.Mass transf...

In this work the physical-chemical properties of asphaltene-resin-paraffin deposits are studied. Their component composition was determined. The results obtained basis for selection effective solvents and choice method removing from oil reservoirs. Two hydrocarbon with brands “TSK А” B” were tested. solvent ability

The data focused on the value of immunofluorescence on paraffin-embedded sections are controversial, and it is still difficult to obtain reproducible results. The aim of our study was to evaluate the usefulness of immunofluorescence on paraffin-embedded renal section in detecting immune complex deposits in IgA nephropathy (n = 24), membranous glomerulopathy (n = 22) and lupus nephritis (n = 24)...

An excess Gibbs free energy model is applied to in®estigate the influence of n-paraffin composition on the aging beha®ior of wax-oil gel deposits known to form in subsea petroleum transport pipelines. The aging of wax-oil gels occurs by a counterdiffusion process where wax molecules with carbon numbers greater than a critical carbon num( ) ber CCN diffuse into the gel matrix, and ®ice ®ersa. Mo...
