EPA tests oil dispersants for the Gulf of Mexico
July 8, 2010
The EPA has announced the results of its testing of the dispersant chemicals
being used to mitigate the effects of the oil spill in the Gulf of Mexico, and their latest results included the positive news that none of the chemicals tested, including the one actually being used right now, appeared to cause any "biologically significant endocrine disrupting activity". We have received lots of calls from people trying to initiate their own technological solutions to the oil problem
, since we sell a wide range of pumps. Unfortunately, the biggest problem is that oil and water are so dramatically different in terms of their fluid properties that the right pump for moving sea water is radically different for the right pump for moving crude oil. Water flows best through centrifugal pumps
that operate at very high speeds; oil is generally moved best by positive-displacement pumps
that physically push the fluid along. When the two are mixed -- particularly in highly variable proportions, as they are in the Gulf, it's almost impossible to pump the mixture reliably.
