System device for producing needle coke crude oil through catalytic slurry oil

Abstract

The invention belongs to the field of catalytic slurry oil deep processing and particularly relates to a system device for producing needle coke crude oil through catalytic slurry oil. According to the device, a mixer 1, the top of a catalytic slurry oil extraction tower 2, the top of an aromatic-hydrocarbon-rich oil separation tower 4 and the top of an aromatic-alkane-rich oil separation tower 5 are sequentially connected through pipelines. The bottom of the catalytic slurry oil extraction tower 2 is connected with a gas stripping tower A8-1. The bottom of the aromatic-hydrocarbon-rich oil separation tower 4 is directly connected with a gas stripping tower B8-2. The bottom of the aromatic-alkane-rich oil separation tower 5 is connected with a gas stripping tower C8-3. A gas outlet of the gas stripping tower A8-1, a gas outlet of the gas stripping tower B8-2 and a gas outlet of the gas stripping tower C8-3 are sequentially connected and then connected with a condenser 7 and a solvent tank 6, and the bottom of the gas stripping tower B8-2 is connected with a hydrofining reactor 9. The device fully utilizes petroleum resources and turns waste into wealth, the catalytic slurry oil can be utilized at high value, and the produced needle coke crude oil can serve as needle coke raw materials high-additional-value products.

Description

technical field

[0001] The invention belongs to the field of deep processing of catalytic oil slurry, in particular to a system device for producing needle coke raw material oil from catalytic oil slurry. Background technique

[0002] my country's oil resources are in short supply. With the development of the national economy, the domestic consumption of oil resources continues to increase. According to the "Research Report on the Development of Oil and Gas Industry at Home and Abroad in 2013" compiled by the China National Petroleum Corporation Economic and Technological Research Institute, in 2013 my country's oil The apparent consumption of crude oil and crude oil reached 498 million tons and 487 million tons respectively, an increase of 1.7% and 2.8% over the previous year. There are more than 1,200 enterprises above designated size in the domestic petroleum processing industry. The one-time processing capacity of crude oil in my country is 590 million tons, of which the ...
