Embodiment

[0015] Such as figure 1 As shown, a system based on catalytic cracking of oil and gas includes a cracking chamber 3 and a fractionation tower 10 connected to the cracking chamber 3. A catalytic chamber 6 communicating with the cracking chamber 3 is provided below the cracking chamber 3. The catalytic chamber 6 The bottom of the catalyst regenerator 7 is communicated, the catalytic chamber 6 is communicated with the gas steam generator 2, and the gas steam generator 2 is connected with the decompression orifice chamber 1; the catalytic chamber 6 is communicated with the cracking chamber 3 through the riser 4. Catalysts are continuously produced in the catalyst regenerator 7 to ensure continuous catalysis. The gas steam generator 2 and the decompression orifice chamber 1 ensure that the pressure in the catalytic chamber 6 is constant, and the catalyzed gas passes through the riser 4 to the cracking chamber 3. cracking.

Abstract

The present invention discloses a system based on catalytic cracking of petroleum. The system comprises a cracking compartment and a fractionating tower connected to the cracking compartment, a catalytic compartment is provided and connected to the bottom of the cracking compartment, the bottom of the catalytic compartment is connected to a catalytic agent regenerator, a gas steam generator is connected to the catalytic compartment, and the gas steam generator is connected to a decompression orifice plate compartment. The catalytic compartment is connected to the cracking compartment through a lift pipe. The catalytic cracking system uses less equipment, has a strong processing ability, and can carry out catalytic cracking on various substances in the crude oil and eventually separate them thoroughly, thereby providing various substances wanted by people. The operation of the present system is safe and the quality is stable.

Description

technical field [0001] The invention relates to a system based on catalytic cracking of oil and gas, which belongs to the field of petroleum refining. Background technique [0002] Petroleum, also known as crude oil, is a viscous, dark brown (sometimes greenish) liquid. There are oil reserves in parts of the upper crust. The nature of petroleum varies with the place of origin, the density is 0.8 ~ 1.0 g / cm3, the viscosity range is very wide, the freezing point varies greatly (30-60 degrees Celsius), the boiling point ranges from room temperature to above 500 degrees Celsius, and is soluble in many organic solvents , Insoluble in water, but can form emulsion with water. However, the composition and appearance of oil in different oil fields can be greatly distinguished. Petroleum is mainly used as fuel oil and gasoline, and fuel oil and gasoline constitute one of the most important primary energy sources in the world. Petroleum is also a raw material for many chemical indu...
