Integrated shale oil separating system

Abstract

The invention discloses an integrated shale oil separating system. The integrated shale oil separating system consists of an automatic sand separator, a transverse secondary sand separator, a liquid converter, a gas-liquid secondary separator, a gas collector, an oil-water separator and oil-water secondary separators, wherein the automatic sand separator is connected with the transverse secondary sand separator through a liquid outlet of the automatic sand separator, the transverse secondary sand separator is connected with the liquid converter through a liquid guiding tube, and an air outlet of the automatic sand separator is connected with the gas-liquid secondary separator through a gas guiding tube; the liquid converter is connected with the gas-liquid secondary separator through a gas outlet of the liquid converter, and the gas-liquid secondary separator is connected with the gas collector; and the liquid converter is connected with the oil-water separator through a liquid outlet of the liquid converter, and the oil-water separator is connected with the oil-water secondary separators through oil tubes. By the integrated shale oil separating system, sand, gas, water and oil in a stock solution can be separated; repeated separation is performed, so that the purity of the separated oil is guaranteed, and three phases in the stock solution are recycled; and the integrated shale oil separating system is easy to operate, good in a separation effect and small in environmental constraints.

Description

technical field [0001] The invention belongs to the technical field of shale oil separation, and in particular relates to an integrated shale oil separation system capable of performing gas-solid-liquid three-phase separation on shale oil obtained from exploitation. Background technique [0002] At present, the main method of solid-liquid three-phase separation of shale oil and gas is to sequentially separate solid particles and impurities, exploited combustible gas, water and shale oil from the three-phase mixture. [0003] The Chinese application with the application number 00804688.3 discloses a three-phase separator, which includes a primary separator arranged in the gas region, and a sloped reflux disk arranged in the gas region, which has a lower end located at The portion near the inlet end wall of the tank so that a channel is formed between the lower end and the inlet end wall. It does not perform the function of separating solids, and is not efficient in separatin...

Problems solved by technology

Because the gas, liquid and solid three-phase separator adopts a mallet-shaped body with a complex structure, the production cost is increased, and because it only uses and separates, its overall filtration purity also needs to be improved.
