Abstract
The utility model directs to a crude oil low-water-content online monitoring meter consisting of a measuring pipe. A first sensor and a second sensor are disposed on the side wall of the measuring pipe, wherein the first sensor and the second sensor is axially spaced in an interval of 50-200 mm along the measuring pipe, and the radial concluded angle of the first sensor and the second sensor is 45 degree and 135 degree along the measuring pipe. The utility model introduces the double-beam double-energy measuring method on the prior low-water-content measuring technology in resolving the technical problem of monitoring the mixed water content in the multi-quality low-gas crude oil.
Description
Technical field
The utility model relates to a kind of crude oil low-water-content on-line monitoring instrument.
Background technology
The water percentage of cleaned crude oil is generally less than 5% in the petrochemical industry, but because day output is quite big, accurately measuring in the commerce and trade clearing and deducting water cut has become very important productivity effect data.Along with progress of science and technology, crude oil low-water-content Automatic Measurement Technique has reached higher level.
But because the low moisture measuring system of crude oil of the prior art is at the crude oil physical qualities relatively evenly or change less relatively measurement system and design, so running into trade in commodities crude oil is that many qualities are mixed the situation of failing or containing a small amount of emulsification gas crude oil, designing technique indexs such as its measuring accuracy just are difficult to reach.In order to maximally utilise the pipe-line equipment resource, mix transporting operation and remote oil transportation in the crude oil transportation enterprise and be again comparatively general phenomenon, therefore at present under the working condition, the automatic accurate measurement that mixes the output oil low-water-content has become this field and has been badly in need of the technical barrier that solves at present.For many qualities low gas content crude oil, water percentage, oil density and gassiness variation belong to multiparameter on-line measurement problem, existing one-parameter measuring technique is insoluble, must introduce two-parameter or measuring multiple parameters technology, to can be considered again be that the pseudodensity of oil product changes for oil density, gassiness and other factors vary on the other hand, can be considered the two-parameter measurement problem again from this angle, if can address this problem preferably technically and have important techniques meaning and good popularization value undoubtedly.
Summary of the invention
The purpose of this utility model is can adapt to many qualities crude oil mixed-transferring or contain mixed output oil low-water-content automonitor under a small amount of emulsification gas situation in order to provide a kind of, and this monitor is to introduce two-beam dual intensity measuring method on the basis of existing low moisture measuring technique.
The purpose of this utility model can realize by following measure:
A kind of crude oil low-water-content on-line monitoring instrument comprises measuring channel; Sidewall at measuring channel is provided with the first sensor and second sensor, wherein the first sensor and second sensor along measuring channel axially at a distance of 50-200mm, and first sensor and the radially angle of second sensor on measuring channel are 45 °-135 °.
First radiographic source of described first sensor is Am
241, the distance between this radiographic source first detector corresponding with it is more than or equal to 250mm.
Second radiographic source of described second sensor is Pu
238, the distance between this radiographic source second detector corresponding with it is smaller or equal to 75mm.
The utility model has following advantage compared to existing technology:
1, the utility model is introduced two-beam dual intensity measuring method on the basis of existing low-water-content measuring technique, solves the technical matters of many qualities low gas content crude oil mixed-transferring water percentage monitoring.
2, the utility model is at water percentage 0～5% o'clock, and the pseudodensity that oil density, gassiness and other factor cause changes 0～5%, measuring precision of water content in water 0.05～0.1%; At water percentage 5～10% o'clock, the pseudodensity that oil density, gassiness and other factor cause changes 0～5%, measuring precision of water content in water 0.1～0.2%,
3, the measurement caliber that is suitable for of the utility model is greater than DN125.
