| description | The process of separating the hydrocarbon oil catalytically cracking reaction products includes: introducing oil gas as the catalytically cracking reaction products to the bottom of cold exchange pre-separating tower for counter flow contact with catalytically cracked material from the tower top to lower temperature, leading out heavy components and entrained catalyst powder together with oil slurry from the tower bottom, leading out the catalytically cracked material via side line and extracting light oil fraction and other gas material from the tower top; cooling and separating the material extracted from the top of the pre-separating tower in a triphase separator to obtain gaseous material flow, which is compressed and separated in subsequent unit to produce condensate separated in rectifying tower, and sewage feeding for treatment in a sewage treating system. The present invention can realize effective separation of reacted hydrocarbon oil gas. |
