METHOD OF DETERMINING COMPONENTS IN WATER-PETROLEUM MIXTURE STREAM Russian patent published in 2006 - IPC G01N22/04 

FIELD: crude oil treatment.

SUBSTANCE: invention relates to technology of determining constituents of liquid mixtures, such as emulsions, suspensions, and solutions, and can be applied when separating water-petroleum mixtures into constituents. Method of invention consists in electromagnetic irradiation of water-petroleum mixture stream by means of emitting antenna in microwave region and receiving electromagnetic energy passed through water-petroleum mixture stream by means of reception antenna, which serves to measure values characterizing received electromagnetic emission. When comparing these measured values with calibration values corresponding to different contents of water, petroleum, and solid inclusions in water-petroleum mixture in subject stream, thus obtained comparative results allow one distingue particular components in water-petroleum mixture. This information serves one to properly adjust electromagnetic emission in specified bands within microwave region. Emitting antenna utilized is at least one rectangular waveguide facing with its open end, which is emission aperture, water-petroleum mixture stream. Reception antenna is at least one rectangular waveguide facing with its open end, which is reception aperture, the same stream. Apertures of each waveguide or one of the two waveguides is made truncated at an angle, which is less than minimum Brillouin angle of electromagnetic energy emission.

EFFECT: increased water and petroleum measurement accuracy in presence of salts.
