Automatic determination device and method for oil shale oil content

Abstract

The invention discloses an automatic determination device and method for the oil shale oil content, and relates to the field of oil shale testing and determination. The determination device comprisesan aluminium screening sample tank, a heating device, a dewatering device and a control device, the heating device comprises a heating chamber for containing the aluminium screening sample tank, and aheating element is arranged in the heating chamber; the dewatering device comprises a receiver, a receiver oil bath device, an air inlet pipe and a drying pipe; the aluminium screening sample tank isconnected with the receiver through a high temperature resistant pipe, and an electric valve is arranged on the high temperature resistant pipe; the receiver is connected with the air inlet pipe andthe drying pipe separately through pipes, and electric valves are arranged on a pipe used for connecting the receiver with the air inlet pipe and a pipe used for connecting the receiver with the drying pipe respectively. Accordingly, by collecting oil shale dry distillation products and analyzing water, the oil content of oil shale can be accurately and automatically determined. The device has theadvantages of being simple in structure, low in cost, easy to operate and convenient to carry.

Description

technical field [0001] The invention relates to the field of oil shale experimental measurement, in particular to an automatic oil shale oil content measurement device and a measurement method. Background technique [0002] With the development of unconventional oil and gas fields, oil shale has gradually become a new energy hotspot and is listed as a very important alternative energy source in the 21st century. The oil content of oil shale is the most important property of oil shale, and it is also the most important index to evaluate the quality of oil shale. At present, the low-temperature dry distillation method is generally used in the world to measure the oil content of oil shale. [0003] The low-temperature dry distillation method refers to putting the oil shale sample in an aluminum screen, heating it from room temperature to 520°C at a certain heating rate under air-isolated conditions, and keeping it for a certain period of time, and measuring the oil, water, sem...

AI Technical Summary

Problems solved by technology

Its operation is cumbersome, requiring manual loading and unloading of reaction vessels, inspection devices, control of heating rate and time, multiple determinations of mass, and repeated experiments; the experiment takes a long time

This not only puts forward requirements on experimental conditions and experimenters, but also brings errors caused by experiment operators and laboratory conditions to the measurement results.
