SUMMARY:The Impact of Oil Properties on Seawater-in-Oil Emulsion Formation
 : a Mesocosm Flume Tank Investigation
DESCRIPTION:Paper\n\nWen Ji and Jayanth Yalamanchilli (New Jersey Institut
 e of Technology), Lin Zhao and Timothy J. Nedwed (ExxonMobil Upstream Rese
 arch Company), Roger C. Prince (Stonybrook Apiary), Christoph Aeppli (Bige
 low Laboratory for Ocean Sciences), and Michel C. Boufadel (New Jersey Ins
 titute of Technology)\n\nSpilled oil mixed with seawater and entrained wat
 er bubbles in an oil slick can potentially form an emulsion. The emulsifie
 d oil (i.e., the emulsion) has a significantly increased viscosity, which 
 poses extra challenges to oil spill response. Existing information related
  to the stability of seawater-in-oil emulsions is based on the behavior of
  emulsions in small, closed systems (e.g. small flasks), and some studies 
 have shown that some emulsified oils that exhibited stable behavior in the
  lab readily spread into sheen in an uncontaminated open water system. We 
 have constructed a mesocosm scale flume tank equipped with artificial sola
 r lamps, white-cap mixing water jets, Langmuir cell mixing, and two weirs 
 to remove diffuse sheening components. In this case, the oil spreading is 
 designed to be ‘infinite’ and the oil weathering process is in a mostly ‘n
 atural’ environment in this 8-meter-long, 0.6-meter-wide, and 0.3-meter-de
 ep flume tank, which is filled with 33 g/kg artificial seawater (Instant O
 cean). The system can be operated remotely and monitored through the web. 
 Oil samples were collected at 0 h, 1 h, 6 h, 9 h, 24 h, 48 h, and 72 h to 
 monitor changes in physical-chemical properties such as density, viscosity
 , interfacial tension, water content, water bubble size distribution, and 
 oxygenates with FTIR, etc. The results, we argue, approach reality and cou
 ld help establish an oil spill prediction model, as many natural processes
  were considered and simulated.\n\nTag: Restoration\n\nSession Chair: Ingr
