| Description |
The purpose of the study was to determine the partitioning of
different chemical emulsions breakers between oil and water phases when they
are used to enhance decanting of recovered water from offshore skimming
operations. This proposed effort built upon a previous projects entitled
"Testing at Ohmsett to Determine Optimum Times to Decant to Temporary
Storage Devices (Project 298)" and "Extending Temporary Storage Capacity
Offshore With Emulsion Breakers (Project 395)" where S.L. Ross tested at
Ohmsett to decant at several different periods to determine the best time to
separate excess water collected during oil spill clean-up operations.
Knowing the proper time to decant insured that the captured oil was not
re-released into the water and it will allow the skimming vessel to remain
on location longer. Adding chemicals to this operation will further aid
water/oil separation and allow for more frequent and cleaner decanting. |
