From January to March, Maoming Petrochemical's propylene production reached 30,400 tons, an increase of 0.14 million tons from the same period of last year, a record high in the same period.
The gas fractionation unit is the only propylene production unit of Maoming Petrochemical and belongs to a downstream unit of the four-catalyst combined unit. This year, Maoming Petrochemical continuously optimizes the operation of the gas separation unit, and it is preferred that the optimized catalytic catalyst be used to improve the catalytic reaction activity and improve the unit. Octane value; In the face of the difficulty of stable pressure control at the top of the propane tower in the beginning of this year, the company actively organized technical personnel to carry out special technical research, through optimizing the position of the feed inlet under the depropanizer tower, feeding temperature, and carefully adjusting the tower. The top-return flow rate, post-cold temperature parameters and other measures have effectively increased the smooth rate of pressure control at the top of the tower, and eliminated the roadblocker for increasing the production of propylene. On this basis, the new gas return to coking liquefaction since February of this year was also grasped. The smooth operation after the implementation of the gas project has created favorable conditions for further increase of propylene production.
