High range temperature thermal dismantling method in processing oil shale

Abstract

This invention consists of a new thermal dismantling method that enables reaching very high temperatures of 1000° C. for transforming any quality oil shale into directly refinable shale oil and to shale gas equal to natural gas, and as a by-product producing water and hot air, resulting in ash production where the ash is transformed into solid fuel by adding organic and non-organic additives and the residue of the burned solid fuel is used as raw material for other industrial products such as clinker, insulation material; by using its own solid fuel to raise and reach the high range temperature without the need to use any other type of fuel and without using water for the cooling system.

1 - A high range temperature thermal dismantling method conducted in between 850° C. and 1000° C. in processing oil shale, bituminous sand in order to obtain shale gas which matches the specifications of the natural gas, shale oil which is consistent in specifications, structural and chemical composition with the crude oil, so that it can be sent directly to the crude oil refineries without need for specific treatment or hydrogenation process, wherein
 the dismantling process is conducted in a reactor positioned inside a furnace in which solid fuel which is oil shale ash taken out of the reactor and cooled and then treated is burned indirectly to heat oil shale placed inside the reactor, 
 shale gas, shale oil, water, purified hot air are extracted separately during dismantling process, 
 shale gas and water vapour are separated by using vacuum pump to be directed into condenser, after the condenser the shale oil and the water are liquidised while the gas has been directed to gas tank, 
 shale oil is separated from the water by using separation tower and water is directed to the water tank, 
 the hot air is pulled from the furnace and directed to the washing and cleaning unit, after that the hot air is directed to the heat exchange and precipitator unit, and 
 the resulting oil shale ash from the reactor is then sent out to be cooled and then treated to obtain what is called a solid fuel. 
 
     
     
         2 - The high range temperature thermal dismantling method of  claim 1 , wherein the liquid or gas fuel is burned in the furnace until the temperature reaches to 550° C., and then the liquid or gas fuel source is replaced with solid fuel to raise the temperature to 1000° C. at standard atmospheric pressure.
