Problems solved by technology

In the above process, due to the small surface area, slow heat transfer rate and poor condensation effect of the Erlenmeyer flask, part of the shale oil and water escape in the form of gas; Affected by factors such as temperature, it is difficult to measure accurately; during the process of transferring the oil-water mixture before the determination of water quality by the toluene method, the loss of shale oil and water will also be caused, so the traditional method of measuring the oil content of oil shale is prone to large errors
In the process of using the toluene method to measure the water quality, because toluene and water are in the emulsion state for a long time, it needs a long time of heating and standing, the operation time is long, and the work efficiency is low.

Abstract

The invention relates to an oil-water separator in oil shale dry distillation analysis and an oil-water content determination method. According to the invention, an oil absorption device, a water absorption device and a tail gas recovery device are connected to the end of a conduit of an aluminum retort or a Gray-King dry distillation device in order. The outside of the oil absorption device is provided with a constant temperature heating device, and the inside of the oil absorption device is loaded with an oil-absorbing material. The water absorption device contains a water-absorbing material inside. Compared with a toluene method for distillation separation of shale oil and water, the method provided in the invention greatly shortens the experimental time, avoids using toluene and other dangerous reagents, improves work efficiency, saves a lot of electric power and water energy, and has no damage to the ecological environment. Compared with a conical flask condensation method, the method provided in the invention has the characteristics of simple and convenient operation, and sufficient absorption of shale oil and water. The method uses an analytical balance to directly weigh the weight gains of the oil absorption device and the water absorption device, the weighing precision is high, and the precision and accuracy of the determined oil content and moisture content are both superior to traditional methods. The separator has the advantages of simple structure, low cost, convenient operation, simplicity and practicability.

Description

Technical field: [0001] The invention relates to a detection technology for exploration, development and utilization of oil and gas resources, in particular to an oil-water separation and collection device and an accurate measurement method for dry distillation measurement of shale oil and water in oil shale exploration, development and utilization. Background technique: [0002] The oil content of oil shale is the most important indicator for the development and utilization of oil shale. At present, the oil content of oil shale is usually measured by aluminum retort carbonization method and Gejin carbonization method. The biggest shortcoming is the determination of oil content after the oil-water mixture is obtained. The steps are complicated and the result error is large. The traditional method uses a conical flask immersed in an ice-water bath to collect the shale oil and water distillate obtained by dry distillation, and then uses the toluene method to separate the colle...
