Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] Such as figure 1 As shown, the process of the continuous oil-sand separation method includes ore lifting and transportation, crushing of ore clusters, ore screening, initial dissolution, oil-sand separation, sand-water separation and auxiliary operation solvent preparation.

[0023] Ore sands are often placed, stored, and transported in the open, and exposed to the atmosphere. The light components of oil in ore sands rarely exist, and basically all of them have a boiling point above 210°C. This is the reason for choosing diesel oil as a solvent; Before the installation, it must go through mineral processing to remove the stones and metal objects entrained in the ore, and make the sand aggregate particle size <50mm;

[0024] The solvent preparation refers to preparation of auxiliary water, preparation of auxiliary diesel oil, mixed liqui...

Abstract

This invention has disclosed a kind of continuous oil and sand separated method and equipment, its craft course including ore in sand form is promoted and sent, the group of ore in sand form is broken, the ore in sand form is sieved, dissolve for the first time, the oil sand is separated, the solvent is compounded, main raw materials include the ore in sand form of oil, industry water, diesel oil, let the base phenol gather oxygen and ethylene ether, alcohol ether sulphuric acid sodium, operate and go on under the atmosphere, it is not higher than 90deg.C to operate temperature, adopting the low-voltage steam, the boiler is easy to solve to form a complete set. The oil content of ore in sand form demands to be greater than 90%. Adopt and originally send and draw the petroleum from the oil placer, the procedure is short, there is little equipment, all is the carbon steel equipment, the atmosphere is left and operated. So produce the construction investment provice of the device, the production cost is low, suitable for popularizing adopting in the small and medium enterprise, if can built with the oil plant jointly, convenient on is it offer postprocessing of petroleum to draw, expenses will low, have kinder economic benefits.

Description

technical field [0001] The present invention relates to a method and equipment for extracting oil from minerals, more specifically: relates to a method and equipment for extracting oil from ore in oil sand mines. Background technique [0002] Oil sand ore is an important oil resource, and there are abundant reserves in Northeast my country, Northwest China and Inner Mongolia. The oil content is more common at 10% to 15%. 30% to 70% of the residual oil is contained in the sand and gravel layers in the oil production wells of the abandoned oil fields that have been exploited, and the oil resources are non-renewable. The demand for domestic oil is increasing day by day, and the current oil price in the international market is constantly rising. , China has become the second largest oil consumer in the world after the United States. Therefore, it is of great economic and strategic significance to extract oil from the ore of oil sands to make full use of n...
