Technology for sorting oil shale through pressure two-product heavy media

Abstract

The invention discloses a technology for sorting oil shale through pressure two-product heavy media, and belongs to the oil shale industry field. The technology is suitable for the processing and utilization industry of oil shale. By means of the technology, oil shale raw ore is pre-screened through a 25mm sifter, after being crushed, oversize products are mixed with undersize products, and a pressure two-product heavy medium cyclone is adopted for sorting; and underflow and overflow of the pressure two-product heavy medium cyclone are subjected to water removal and medium removal, and two products of concentrates and tailings are obtained. According to the technology, the process is simple, the sorting efficiency is high, energy consumption is low, the oil refining cost can be reduced, and good economic benefits can be obtained.

Description

technical field [0001] The invention relates to the field of oil shale separation, in particular to a process for separating oil shale with pressure and two-product heavy medium. Background technique [0002] Oil shale is an unconventional oil and gas resource. After thermal processing, oil shale can be made into shale oil. As an important chemical production raw material, shale oil is widely used in the production of various materials. Oil shale organic matter is thermally decomposed to form It is a brown liquid product similar to natural petroleum, but contains more unsaturated hydrocarbons than natural petroleum, and contains non-hydrocarbon organic compounds such as nitrogen, sulfur, and oxygen. With the depletion of non-renewable fossil energy such as oil, natural gas, and coal, oil shale is listed as a very important replacement resource in the 21st century due to its abundant resources and the feasibility of development and utilization. [0003] At present, in my cou...
