Problems solved by technology

However, the problem with this method is that the different types of hydrocarbons carried by the raw catalyst are not stripped separately, causing some easily stripped hydrocarbons to stay in the settler for too long, resulting in excessive cracking reactions and thermal cracking reactions
The reaction oil gas generated by this method contains a large amount of catalytic wax oil with a boiling point greater than 350°C, and even fractions with a boiling point greater than 500°C. Difficulty

Abstract

The invention relates to a fluid catalytic cracking gas-oil separating and stripping device and a method thereof. The fluid catalytic cracking gas-oil separating and stripping device comprises a first-level cyclone separating device, a second-level cyclone separating device, a first stripper and a second stripper, wherein an inlet of the first-level cyclone separating device is connected with an outlet of a lifting pipe reactor; diplegs of the first-level cyclone separating device and the second-level cyclone separating device respectively extend into the first stripper and the second stripper; gas-phase outlets of the first-level cyclone separating device, the first stripper and the second stripper are connected with an inlet of the second-level cyclone separating device, and the first stripper and the second stripper are connected by a catalyst pipeline. The corresponding method comprises the following steps of: separating reaction oil gas and a catalyst when entering the first-level cyclone separating device, wherein the catalyst enters a regenerator after being stripped twice, and the reaction oil gas and each stripped gas phase enter a follow-up fractionating system after being separated by entering the second-level cyclone separating device. The device and the method can quickly extract the reaction oil gas out of the device, and gas phase hydrocarbon carried in spent catalyst granule gaps is quickly stropped and extracted, thereby reducing hydrogen content in coke and internal coking trend of the device.

Description

technical field [0001] The invention relates to equipment and technology in catalytic cracking process. More specifically, the liquid catalytic cracking oil and gas separation and stripping equipment and method are used to increase the yield of liquid products, reduce the coke yield and reduce the tendency of coking inside the settler. Background technique [0002] The development of rapid separation technology in the riser outlet area has always been one of the important goals of riser reactor research, because the rapid separation device in the riser outlet area has two main functions. , quickly separated from the catalyst, avoiding the thermal cracking reaction, thereby increasing the yield of the target product; the second is to minimize the catalyst being carried out with the oil and gas, and reduce the particle concentration at the inlet of the cyclone separator, thereby reducing the unit consumption of the catalyst. At present, the rapid separation devices in the out...
