The interaction between dispersed crude oil droplets and particulate matter

Author affiliations

Abstract

In this study, the effect of particulate matter type, temperature, oil type and weathering degree on the interaction between dispersed crude oil droplets and particulate matter was investigated. The increase of total petroleum hydrocarbon (TPH) percentage in oil–particle aggregates (OPAs) could be attributed to the increase of oil polarity or viscosity. For small size particulate matter, there was a fine dependence relationship between the TPH percentage in OPAs and the oil viscosity and the content of polar components, respectively (R2 > 0.7502). And the total organic carbon content also played an important role in the formation of OPAs. The petroleum hydrocarbon extracts of OPAs showed a decrease in short-carbon-chain components and a relative increase in long-carbon-chain compounds. Petroleum hydrocarbon compounds trapped by three types of particulate matter exhibited a similar change tendency, but there was no apparent difference in the residual TPH percentage in water.
