[0014] The present invention will be further described below in conjunction with the examples, but not as a basis for limiting the present invention.
[0015] The present invention provides a kind of calculation method of the octane number loss in catalytic cracking gasoline process, and this method comprises the following steps:
[0016] Step 1, according to the historical operation data of the catalytic cracking gasoline unit, collect the pump inlet filter differential pressure, outlet main pipe temperature, reducer temperature, heat exchanger shell side outlet pipe temperature, refined gasoline output Calculation parameters such as device temperature and octane number data of raw oil;
[0017] Step 2: Substituting the processed data into the formula to calculate the octane number loss in the process of catalytic cracking gasoline, the specific calculation formula is:
[0018]
[0019]
[0020] In the formula: F is the octane number loss in the process of catalytic cr...
