Guangzhou Petrochemical takes multiple measures to increase naphtha production

After nearly a month of continuous optimization, Sinochem News.
As of July 15th, the heavy naphtha yield of Guangzhou Petrochemical's hydrocracking unit has increased from 10.
8% to 17%, and the monthly output of heavy naphtha can be increased by nearly 3,000 tons
.

This year, the benefits of naphtha are relatively high, and Guangzhou Petrochemical has chosen to optimize the equipment to increase the production of naphtha as its main direction
.

It is understood that Guangzhou Petrochemical’s hydrocracking unit is a “medium oil type” hydrocracking unit, which mainly produces jet fuel and diesel oil.
Heavy naphtha is only a by-product.
Increasing the production of heavy naphtha will have a certain impact on the product quality and operation of the unit.

.
For this reason, the installation personnel faced difficulties and adopted a gradual approach to achieve a steady increase in the production of heavy naphtha

First, the plant technicians increased the extraction volume of heavy naphtha by increasing the temperature at the top of the main fractionation tower by about 3 degrees Celsius, and the output of heavy naphtha increased by up to 4 tons per hour
.
In view of the problem that affects the flash point of jet fuel during the increase in production, the installation personnel continued to optimize, by adjusting the load of the jet fuel stripper reboiler, appropriately reducing the dry point of jet fuel, reducing the amount of extraction, and ensuring the stability of jet fuel quality

Secondly, on the basis of the initial results, they increased the temperature at the top of the main fractionation tower by 2 degrees Celsius to increase the yield of heavy naphtha
.
However, the heat load of the fractionation tower changed after the temperature increased.

Once again, on the basis of the results achieved in the previous times of heating, they also tried to continue to increase the temperature of the device by 1.
