ABSTRACT:
Measuring the foaming characteristics of crude oil comprises saturating the crude oil with a gas inert to the crude oil under high pressure and passing the gas-saturated oil into a flash separator. The amount of foam formed is measured with respect to the amount of gas withdrawn from the flash separator and the amount of oil contained therein. The apparatus comprises a gas-oil saturation vessel, a transparent elongated horizontal flash separator, an oil inlet line in one end of the flash separator, an oil outlet line in the bottom portion of the flash separator at the end opposite the oil inlet, a gas outlet line in the upper portion of the flash separator between the oil inlet and oil outlet line, a pressure equalization line in communication with the upper portion of the flash separator, the gas outlet line, and the oil outlet line, a weir for maintaining a layer of oil in the lower portion of the flash separator at a controlled level, a transverse baffle extending from the upper portion of the flash separator to a point below the height of the weir, located near the weir and upstream thereof, means for measuring the oil flow rate from the flash separator, means for measuring the gas flow rate from the flash separator, means for controlling the back pressure within the flash separator, means for controlling the temperature in the gas-oil saturator and the flash separator, and means for measuring the foam volume in the flash separator.
