Method of removing water and contaminants from crude oil containing same

摘要: A method for contaminant and water removal from crude oil. The involves recirculating at least a portion of the dewatered into dehydrator. dehydrator contains heated dehydrated oil surface or adjacent thereto is maintained temperature sufficient to vaporize any contacting be treated in It has been found important maintain substantially uniform below vaporizing order effectively treat dewatering purposes. Significant fluctuations are typically realized by dehydrators since heat enthalpy removed Such lead process complications upset therefore undesirable. instant invention recognizes this limitation reduces foaming provides smoothly running efficient dehydration process.
