The invention provides a piezoelectric two-phase flow ultrasonic atomization spraying nozzle. The piezoelectric two-phase flow ultrasonic atomization spraying nozzle comprises a piezoelectric vibrator, an amplitude-change pole, a second end cover and a first end cover; the piezoelectric vibrator and the amplitude-change pole are connected through a connecting bolt; an air inlet connector is installed at the tail of the connecting bolt; the second end cover is fixed to the front end of the amplitude-change pole; a laval type valve element is fixed into a step hole of the amplitude-change pole and a groove of the second end cover; a liquid inlet hole is formed in the hole wall face of the step hole of the amplitude-change pole; a plurality of flow guide holes are formed in the positions, close to an outlet, of the laval type valve element in the radial direction; the first end cover is threaded connection to the second end cover; a radial positioning ring is arranged at the position of a clamping groove in the back end of the first end cover; a step type taper valve is installed on the radial positioning ring; the step type taper valve and a vibration separating plate are connected through an adjusting bolt; a resonance chamber is formed between the vibration separating plate and the top end of the first end cover; and a plurality of flexible pipes are arranged in the resonance chamber. According to the piezoelectric two-phase flow ultrasonic atomization spraying nozzle, a large number of superfine fog drops are generated under the low-energy working condition, and the shortcoming that large pulverization amount, small grain size, low power dissipation and directed spraying cannot be considered at the same time through in the traditional technology is overcome.

Disclosed and claimed is a microemulsion-based demulsifier composition and a method of demulsifying an emulsion comprising hydrocarbon and water. The demulsifier composition includes (i) an oil-like phase comprising at least one nonionic surfactant having a hydrophilic-lipophilic balance (HLB) of less than about 9; (ii) a coupling agent capable of stabilizing the demulsifier composition; (iii) at least one water-soluble or dispersible nonionic surfactant that is different from the at least one nonionic surfactant in the oil-like phase; (iv) at least one additional surfactant selected from anionic, cationic, amphoteric, and combinations thereof; (v) at least one nonionic demulsifier; and (vi) water.
