Description
Technical Field
The utility model relates to a petroleum industry measuring instrument technical field especially relates to a water content analyzer of hand-held type crude oil.
Background
At present, the method for measuring the water content of crude oil in various oil fields in China is generally divided into two methods, namely a distillation method and an electric stripping method, which are both manual testing methods. The distillation method is characterized in that a certain amount of oil sample and a water-insoluble solvent are mixed and slowly heated under the condensation of circulating water, and the distillate is controlled to drip into a receiver at the flow rate of 2-5 drops/s. The oil sample, solvent and water distill together, and since the relative density of water is greater than that of the solvent, the water settles to the lower part of the receiver score tube, the solvent and oil enter the flask again to continue distilling and separating until the water amount does not increase at the lower part of the receiver score tube, and the heating is stopped when the upper part of the receiver is clear. The water content was calculated from the amount of sample and the volume of the distilled water. The electric dehydration method is to apply an external electric field to the oil-water emulsion to make the emulsified water in the petroleum polarized and mutually attracted to polymerize into free water and precipitate, and to read the water quantity from the graduations of the measuring cylinder for taking oil samples.
The prior art has the following defects: the distillation method and the electric desorption method have the defects which are difficult to overcome, and the operation is careless, and certain dangers are brought to the laboratory staff. Meanwhile, the two methods have low measurement efficiency, waste time and labor and are difficult to meet the requirement of fast production in the petroleum and petrochemical industry.
By applying for a search for new, there is currently no such patent.
