Field water content of crude oil centrifugation mechanisms of determination
Hot Zi Li forever? Abra (Xinjiang Petroleum Administration Associate Institute of East oil field exploration and proliferation corporate laboratories, Fukang 831 511)
Abstract: centrifugation and distillation of crude oil can be estimated via the suiting water content, but the method, time-there are numerous differences, but the conclusion condemn little. The former time-short, which demanded a longer time, centrifugal water content decision of crude oil within the demonstration of its structural significance.
Keywords: centrifugation; distillation; water First, the untested contents and methods
Centrifugation is the equivalent width of crude oil and solvents into conical centrifuge tube with Centrifuge Centrifuge tube subsequent centrifugation inside the direction of read the foot of the breadth of water and sediment. Preheat the polls will be churning through 3 minutes, has weighed right away into a centrifuge tube, weighed 50 ± 0.1g. Centrifuge tube letting go 0.2ml25% of the demulsifier, and Absolute petrol towards 100ml, and shake. Then, the centrifuge tube into the centrifuge inside the centrifuge 10min. To be withdrew one time shutdown centrifuge tube, list the tube at the precursor of the water and sediment capacity V. Water and sediment polls are calculated with the following:
Water and sediment polls via the fraction content = (1-V1) V / G × 100%
The formula: V1-free water (free water width end marriage ceremony via the whole breadth of oil sample); V-test from the water and sediment size (ml); G-sample descending implement (g).
Distillation is supplemented within the ballot water is not miscible with the formation of lowered boiling print organic solvent mixture, and the special deducing gadgets inside specialized water. Receptors within the distillate gathered by the cool water volume to read. To preheat the vote had severe waking 3 minutes, cleansed and thirsty round foundation flask weighed hundred ± 0.1g experiment has been shaken, add 100ml water petrol (or solvent oil), and put a couple of teeth zeolite, and otherwise shake. Equipment established afterwards the heating, and serenity the update speed. ten minutes ago passage of warming rate can be faster, but the come back flow was not linear. Should be seared leisurely as shortly as 50 minutes, until the receiver is no longer amassed in the volume of water increased, and the towards the top distillate ceases decisively crystal clear heating. Remove the water receivers on the 50 charity water go swimming tub for thirty minutes, full of water and oil separation, and otherwise read the volume of water.
II, Results and Discussion Field crusade locality in Shanan steal B2112, B2019, B2007,
SQ2479, SQ2458, SQ3016 oil wells and other 6 tests (sampling days of the year are March 26, 2002), respectively centrifugation and evaluated water distillation method, the findings are as follows:
Table 1, centrifugation and distillation styles findings table
Centrifugal styles results% 25.045.060.029.02.08.0
Distillation process results% 26.046.060.530.02.08.0
The absolute difference between pair findings 1.01.00.51.00.00.0
According to Table 1 Comparison of two methods:
1, accuracy comparison: the theoretical and functional solutions of high appropriateness distillation method, because crude oil, water and oil to pattern a very small boiling publish solvent mixture, so that the oil tryouts consisted adequate distilled water. I am an expert from China Toys Suppliers, usually analyzes all kind of industries situation, such as custom snow globes , and convex mirrors.
