| Abstract;Emulsification, the formation of a water-in-oil mixture which is often observed once oil spill incident happens on the sea surface, is one of the stickiest problems to be encountered in oil spill responses because it gives the spilled oil very high viscosity and volume inflation due to much water trapped in the oil. Preferred approach to resolve this problem is demulsification of the mousse oil on site which releases the water content from the oil to retrieve the intrinsic fluidity of the oil again and substantially expand the capacity of temporary oil storage. This paper presents laboratory test to assess the demulsification effectiveness of some chemical agents in Couette-Taylor flow. Preliminary tests in a rotational rheometer were conducted with various surfactants such as PEG-10 laurate, sorbitan laurate, diethylhexyl sodium sulfosuccinate as well as other market products. The results showed that dissipation energy is very important factor to promote the emulsion break, and reaction speed is almost proportional to the energy dissipation. The preliminary test results were applied to a large size test equipment which employs Couette-Taylor flow. The paper will include the performance test results of this device. (author abst.) |
