Abstract

The invention discloses a reflux type oil sand oil content and moisture synchronous determination system and a determination method thereof. The device comprises a heating device, an extraction device, a reflux device and a condensation device. The extraction bottle of the extraction device comprises a bottleneck, a first bottle body, a second bottle body and a liquid channel, the second bottle body is placed inside the first bottle body, the bottleneck top of the second bottle body is just located at the bottom of the first bottle body's bottleneck, a U-shaped channel is formed between the first bottle body and the second bottle body, the second bottle body is anon-glued filter cylinder, the bottom of the first bottle body is provided with the liquid channel, a columnar adapter tube is sleeved outside the liquid channel, a gas distribution plate is also disposed between the adapter tube and the liquid channel, and the bottom of the adapter tube is connected to the heating device. The method provided by the invention can respectively determine the oil content, moisture content and solid residue content of an oil sand sample, and avoids the error brought about by direct weighing of solid residue and water mass and then acquisition of the oil content through subtraction method.

Description

technical field [0001] The invention belongs to the technical field of detection and analysis of oil content and moisture in oil sands, and in particular relates to a simultaneous measurement system and method for backflow oil content and moisture in oil sands. Background technique [0002] Oil sands, also known as asphalt sands, heavy oil sands or tar sands, is a widely distributed and abundant unconventional energy source. There are oil sand resources in more than 70 countries including Canada, Venezuela, Russia, the United States and China. At present, the world's proven oil sand resources are about 3.7 trillion barrels, equivalent to about 300-600Gt of heavy oil. Typical oil sands generally contain mud sand, oil and water, the mass fraction of which is 70%-80% mud sand, 5-30% oil, and less than 10% water. With the increasing demand for energy in today's world, the further deterioration of the contradiction between supply and demand, the gradual reduction of traditional ...
