The dynamics of diluted bitumen derived oil-mineral aggregates, part III / by Casey M. O’Laughlin, Brent A. Law, Vanessa S. Zions, Thomas L. King, Brian Robinson, Yongsheng Wu. : Fs97-6/3362E-PDF
"The size, settling velocity and bulk density of oil-mineral aggregates represent valuable and sought-after components of predictive oceanographic models designed to forecast the fate of oil spilled in marine and coastal environments. A series of wave tank experiments to analyze the in situ formation of oil-mineral aggregates from spilled diluted bitumen have been completed, using a concentration of 50 mg/L-1 of fine-grained sediment (median size 7.5 µm) and chemically dispersed Access Western Blend and Cold Lake Blend diluted bitumen. High-resolution images of settling particles were captured and analyzed for particle size, settling velocity and effective particle density. Tested conditions included colder (< 10°C) and warmer (> 10°C) water with an average salinity of 29.3 ppt. Maximum oil droplet sizes ranged from 750 µm to >1 mm, and the rate of particle clearance from the water column from 0.005 to 0.1 mm·s. Results are compared with those of recently published companion reports characterizing previous colder and warmer water, low sediment concentration (15 mg/L-1) experiments. Results are discussed in the context of sediment flocculation and dispersant efficacy"--Abstract.
