Effective clean-up of oil spills due to their negative environmental and economic impact is of capital importance. Clean-up of oil by sorption is considered one of the most desirable choices, because oil can be completely removed without causing any secondary pollution. Natural organic sorbents had been investigated and developed to control oil products‘ spills. Plant biomass is a renewable resource which can be converted into various materials and energy. Hemp (USO-31), as a textile industry waste, was used as an oil product sorbent material. The present study examines hemp sorption capacity of water using different fractions of hemp raw material to be used in oil/water mixtures. The experimental research revealed that water sorption capacity depends on fraction size and sorption time. The results of water sorption capacity of 2.5 and 5.0 mm after 1440 min were 4.74 and 4.67 g water/g dry sorbent, respectively. Labai svarbu efektyviai likviduoti išsiliejusius naftos produktus dėl jų neigiamo poveikio aplinkai ir ekonomikai. Naftos produktų valymo metodas pasitelkiant sorbentus yra laikomas vienu iš geriausių pasirinkimų, nes produktai yra absorbuojami sorbentų, nesukeliant jokios antrinės taršos. Natūralūs organiniai sorbentai buvo tiriami ir tobulinami, siekiant kontroliuoti naftos produktų išsiliejimus. Augalų biomasė yra atsinaujinantis išteklis, kuris gali būti naudojamas įvairioms medžiagoms ir energijai išgauti. Kanapių spaliai (USO-31), tekstilės pramonės atlieka, buvo tiriami kaip naftos produktų sorbentas. Buvo išnagrinėta kanapių vandens sorbcija naudojant įvairias šios medžiagos frakcijas. Eksperimentinis tyrimas parodė, kad vandens sorbcija priklauso nuo frakcijos dydžio ir sorbcijos laiko. Tyrimų metu buvo nustatyta vandens sorbcijos geba – 4,74 ir 4,67 g vandens/g sauso sorbento 2,5 ir 5,0 mm pavyzdžiams po 1440 min atitinkamai.

Abstract-The spontaneous imbibition has been a subject of the scientific interest being a background process for numerous industrial technologies and occurring in the natural environment. In literature the experimental and theoretical results regarding this phenomenon describe the media imbibition with single-phase liquids and the relation between the process rate and media characteristics. The imbibition of oleophilic/hydrophobic porous structures with two-phase liquids, only one phase of which was wetting, is an objective of the current publication. The main purpose is to estimate the influence of both the dispersed phase concentration and surfactant fraction on the discussed process. The imbibition rate was investigated during model experiments with stabilized oil-in-water emulsions, which had dispersed phase concentrations of 10 vol%, 30 vol%, and 50.vol%. The prepared emulsions differed by the fraction of the added surfactant, i.e. 1.vol%, 2.vol%, and 5 vol%. The obtained results allowed to conclude that at the h im ≥0.02 m, the dispersed phase concentration and viscosity decreased versus the height. However, the raise of the surfactant fraction caused the increase of mass and height of the imbibed emulsions in porous medium. Moreover, it provided the increase of viscosity and the change of emulsions behaviour as a liquid.
