Embodiment
[0047] The examples illustrate the gasoline separation effect of the catalytic cracking oil-gas separation method provided by the present invention.
[0048] According to attached figure 1 The shown process separates the catalytic cracking reaction oil and gas, introduces the oil and gas into the main fractionation tower, operates the catalytic cracking main fractionation tower to make the top discharge into gasoline and fractions below C4, and the main fractionation tower sequentially separates diesel oil and heavy diesel oil from top to bottom and oil slurry; gasoline and fractions below C4 are introduced into the gasoline fractionation tower to separate heavy gasoline fractions, light gasoline and fractions below C4, and fractions below C4 are introduced into the subsequent absorption stabilization system to separate light gasoline fractions, liquefied gas and dry gas .
[0049] The flow rate and composition of oil and gas in catalytic cracking reaction are shown in Table...
