Description
Technical field
The utility model relates to crude oil physical characteristics determination techniques field, particularly measures the condensation point of crude oil, is the instrument of a kind of direct measurement condensation point of crude oil, wax precipitation piont, provides parameter for production, research, the conveying of crude oil provides with relevant PROCESS FOR TREATMENT.
Background technology
At present, the method for survey condensation point of crude oil is that GB/T510 surveys method.
The process that GB/T510 surveys method is, when crude oil temperature is reduced near condensation point of crude oil, after the temperature range of finding out condensation point, just takes lowlyer 2 ℃ or adopt highlyer 2 ℃ than the temperature that does not move than the temperature that moves, and experimentizes again.Like this repeated experiments improves 2 ℃ when liquid level is moved until determining certain experimental temperature can make the liquid level of sample stop motionless, just get to make the motionless temperature of liquid level as the sample condensation point.The temperature range of condensation point is that liquid level position does not move or never move to mobile temperature range from moving in the test tube.
GB/T510 surveys the experimental result regulation of method: two results' of same operator's replication difference should be above 2 ℃.Two results' of two laboratory propositions difference should be above 4 ℃.
GB/T510 surveys the method shortcoming: utilizing GB/T510 survey method to survey condensation point must be quantitatively through heating, quantitatively the repeatedly repetitive operation of cooling just can be finished, because measure relatively difficulty or quite complicated of temperature that crude oil can not flow just, so just in generation, just can not the little a certain temperature of flow temperature than table crude oil for more condensation point temperature, for same operator or different operating person permissible error big (2 ℃～4 ℃).Because permissible error is bigger, people are restricted in the effect of using this parameter of condensation point, also make the correlativity of this parameter of condensation point of crude oil and other crude oil property parameter thicken unclear.
The utility model content
The purpose of this utility model is: a kind of condensation point of crude oil analyzer is provided, and the test data that makes condensation point of crude oil is science, accurate and practical more; Alleviate difficulty, the complicacy of test, the change manual operation is automatic test.
The technical solution adopted in the utility model is: the condensation point of crude oil analyzer mainly is made up of electronic balance, super circulator bath, hot and cold water circulation casing, windproof sliding cover, temperature sensor, computing machine.Be fixed with hot and cold water circulation casing on the top of lifter.Hot and cold water circulation casing adopts the recirculated water associated line to be connected with super circulator bath.Super circulator bath is by water cycle, can provide experiment needed temperature for the hot and cold water casing that circulates.A former oil vessel is arranged in hot and cold water circulation casing.In hot and cold water circulation casing upper fixed electronic balance is arranged.The below of electronic balance is connected with the lacing film connecting line.The lacing film connecting line can hang lacing film.Windproof sliding cover cylindraceous is arranged between electronic balance and hot and cold water circulation casing.Electronic balance has communication connection to connect computing machine, can give computing machine with the data transfer of electronic balance.
In order to make the temperature in the hot and cold water circulation casing, accurately be controlled on the needed temperature of experiment, on hot and cold water circulation casing, be fixed with temperature sensor, there is lead to be connected between temperature sensor and the super circulator bath.Super circulator bath can ensure the needed experimental temperature of hot and cold water circulation casing.
The beneficial effects of the utility model: the utility model condensation point of crude oil analyzer can be measured condensation point of crude oil.Measuring crude oil in cooling procedure, test suspension is at the weight changing curve of electronic balance bottom lacing film; When crude oil was in solidifying point, the weight of the lacing film in the crude oil can increase rapidly, utilized flex point on the test curve to judge the condensation point of crude oil.Remove this and can also measure the wax precipitation piont of crude oil.Changed the method for traditional survey condensation point of crude oil, the data of mensuration more accurately and reliably, assay method is more simple and practical.
