ABSTRACT:
A system is provided for the separation of oil from oily water, particularly where the oily water is available only at relatively low pressures insufficient ot drive a hydrocyclone separator. Particular combinations of pumps and hydrocyclones can be effective in these low pressure situations where the pressure boost required is not substantially greater than a differential pressure at which the pump begins to substantially degrade the volumetric mean size of droplets of oil in the oily water passing therethrough. This is achieved by operating the pump at relatively near its maximum flow rate capacity to substantially reduce on a percentage basis the effect of fluid slippage within the pump. Improved techniques for analysis of oil droplet size distribution are also disclosed.
