Abstract: Rapid dehydration of crude oils containing salt water by addition of minor amounts of polyalkylene polyamines having at least fifty recurring ethylene imine or propylene imine units, the said polyalkylene polyamine being completely alkoxylated at the nitrogen atom with from 10 to 300 moles of ethylene oxide and/or propylene oxide. Using these compounds it is possible to effect dehydration, in an economical manner, of crude oils containing up to relatively large percentages of high molecular weight hydrocarbons.
