Description
A Recovery Device for Retorting Gas Light Oil in Induction Adsorption and Desorption Oil Shale
TECHNICAL FIELD The present invention refers to the retorting and refining technology field of oil shale, and provides a recovery device for retorting gas light oil in induction adsorption and desorption oil shale.
BACKGROUND Retorting of oil shale means that the oil shale is heated to the required temperature in an air-isolated environment, resulting in the pyrolytic reaction of the parent material of oil and the formation of retorting products - shale oil and retorting gas. The shale oil can not only be directly used as liquid fuels for marine turbines, but also can be used to produce liquid fuels such as gasoline and diesel oil through rectification process. At present, for the recovery of the shale oil in the industry, the method of condensing and separating the retorting oil and gas is generally adopted. The retorting oil and gas are treated with cooling, so that the shale oil becomes liquid and precipitate, and the remaining gas is non-condensable gas. Therefore, the lower the cooling temperature of the retorting gas is, the more shale oil is condensed and the higher the oil recovery rate is. However, there is a large amount of gas that needs to be condensed in the retorting process. Moreover, with the decrease of oil content per unit of gas, the condensation temperature also decreases and the cooling amount that needs to be used also increases, which is bound to consume a lot of energy. At present, considering the overall economy in the industry, the final temperature of shale oil recovery process is controlled at 40-60°C. If the temperature is lower, more energy will be consumed and oil cost will be increased. This directly results in a large amount of unrecovered light oil in the gas of the final retorting product. On the other hand, the shale oil is a mixture of various hydrocarbons. From its physical and chemical characteristics, it can be seen that its light component (light diesel oil) has a high partial pressure of vapor at room temperature and is highly volatile. It is easy to be adulterated in the retorting gas, which is difficult to be collected, and there will be a phenomenon of gas with oil. The measured data show that the oil content in the gas of a large retorting and refining enterprise in northeast China is 20-25g/Nm?, and the gas output at the outlet of single retorting device is about 70,000- 80,000Nm*/h. In the 24-hour gas discharge, nearly 36 tons of light oil (light diesel oil) is not recovered and is discharged along with the gas exhaust. According to the average statistics in the industry, the oil content in the retorting gas discharged by oil shale enterprises is about 15-20g/Nm°. Such a large amount of high-quality fuel oil has not been recovered, which not only causes huge waste of resources for refining enterprises, but also causes serious pollution to the environment. Moreover, it also causes potential fire hazard to the production environment and harms the production and personal safety.
The carbon fiber is composed of flake graphite microcrystal and other organic fibers stacked along the axial direction of the fiber. The microcrystalline graphite material obtained by high-temperature carbonization and graphitization has good conductivity and thermal conductivity. Due to its highly developed microporous structure, large adsorption capacity, fast desorption and good purification effect, it is characterized by heat resistance, acid resistance and alkali resistance. The carbon fiber has a wide range of adsorption, and large capacity; the adsorption capacity of gasoline, aldehydes, phenols, alcohols, olefins and other organic vapors is several times to dozens of times greater than the activated carbon, and the oil adsorption capacity is many times greater than the activated carbon. It is characterized by small adsorption resistance, fast speed, rapid and complete desorption.
The induction heating is characterized in that an alternating magnetic field is generated by alternating current, and this alternating magnetic field causes an eddy in the conductive material therein, so that the conductive material heats up rapidly. It has the characteristics of fast heating speed, small heat loss and convenient operation, which can not only shorten the process time, improve productivity and reduce cost, but also improve the heating quality of products. According to its working principle, the heat generated by induction heating is generated inside the conductive material, and the heating element is just the conductive material body. Therefore, the induction heating has uniform heating effect, which is beneficial for improving the overall heating effect of the heated body. Because the conductive material body is also heated, the heating time is greatly shortened and the heating efficiency is high. Meanwhile, the induction heating has small thermal inertia, can be started or stopped at any time, and without preheating, it can realize the fast control of temperature rise and drop. and is easy to realize the automatic control of continuous production.
