Abstract

Abstract: This paper introduced research status and development tendency of physical demulsification technologies and equipment about W/O emulsions in crude oil or waste oil. Applications of external force and field energy to demulsify were discussed respectively. External force demulsification mainly employs cyclones,using centrifugal force,coalescence plate using coalescence force,or membrane device using stress force. Field energy demulsification normally focuses on applying microwave field,ultrasonic field,or electric field. Working mechanism,structure and working process of water hammer harmonic demulsification technology were emphasized. This paper pointed out that the development directions of demulsification technologies should be energy and cost effective,and environmental friendly.

Key words: petroleum, emulsions, demulsification, technology and equipments, water hammer harmonic, petroleum, emulsions, demulsification, technology and equipment, water hammer harmonic
