Catalytic cracking oil refining device based on coupling of microwaves with ultrasonic waves

Abstract

The invention discloses a catalytic cracking oil refining device based on coupling of microwaves with ultrasonic waves. The device comprises a vacuum reaction kettle, a separation kettle and circulating cooling devices used for cooling the vacuum reaction kettle and the separation kettle, wherein a resonant cavity is formed in the vacuum reaction kettle; to-be-refined oil flows through the resonant cavity and is subjected to catalytic cracking under the joint action of the microwaves and the ultrasonic waves; a homogeneous reaction cavity is formed in the separation kettle, oil subjected to catalytic cracking flows into the homogeneous reaction cavity for a homogeneous reaction after a proper modification additive is added to the oil, then the oil flows into the separation kettle through adelayed oil storage bend pipe, reactions including impurity removal, desulfurization, denitrification, suspension flocculation and separation, extraction and the like are performed under the joint action of the microwaves and the ultrasonic waves, then the oil flows into a fractionating tower for rectification, system desulfurization refining is performed finally, and a refined oil product meeting requirements is obtained. Hydrogenation-free refining is realized at low temperature under atmospheric and vacuum pressure in the whole process, refining efficiency is high, the refined oil productis good, refining cost is low, environmental pollution is reduced, and industrial development and upgrade are promoted.

Description

technical field [0001] The invention relates to the field of physical and chemical reaction engineering equipment, in particular to a microwave-coupled ultrasonic wave to refine gasoline and diesel oil by visbreaking catalytic cracking of crude oil, heavy oil, waste mineral oil, and biomass oil under low temperature, atmospheric and reduced pressure conditions. Or base oil; an industrial device for desulfurization, denitrification, flocculation, extraction and complexation of oil at the same time. Background technique [0002] With the deepening of oil exploitation, it has become an irreversible trend for oil to become thicker and heavier. With the rapid development of my country's industry, the proportion of crude oil imported from the international oil market exceeds 87%, and most of these imported crude oil are heavy oil and Super heavy oil, coupled with the huge amount of waste mineral oil in the domestic industry, the oil products produced by general refining technology ...

Problems solved by technology

However, due to the insufficient penetration depth of microwave radiation, the volume of the device and the uniformity of microwave radiation are affected, which is also a key factor restricting the large-scale industrial application of microwave technology.

In order to solve the problem of microwave radiation depth and production needs, some enterprises adopt high-power magnetrons of thousands of watts and add stirring devices. The single extraction process may meet the requirements, but it is necessary to add sedimentation devices for the separation of suspended candle liquid. Therefore, the current Technical structures limit the application of microwave technology in industrial installations
