Petrochina guangxi petrochemical application overview:

l 3.5 million tons/year catalytic cracking unit;

l Due to the requirements of process design, a certain amount of zsm-5 additives should be added to the system;

l LOSA-100 from yueyang sansheng company has been used since October 12, 2018

(Blank calibration was carried out from October 8 to 9 before the trial);

l After 25 days of refueling, the planned reserves were established and calibrated.

Technical agreement guaranteed value:

l Ensure that the yield of LPG is not more than 18.5wt% and the yield of propylene is not less than 6.5wt% (for catalytic raw materials).

l The total liquid output (gasoline + diesel +LPG) of the device was basically unchanged (±0.6).

l The fluidization of the main catalyst is not affected by the quality of the catalyst.

Calibration value after use:

l The yield of LPG was 17.19wt%, and the yield of propylene was 6.57wt% (for catalytic raw materials).

l The total liquid output of the unit (gasoline + diesel +LPG) was basically unchanged (±0.38).

l The fluidization of the main catalyst was not affected.
