Recently, the Changlian catalytic gasoline adsorption and desulfurization unit has operated safely and smoothly for 1,000 days, setting a new record
for the long-term operation of similar refining and chemical units in China.
The plant was put into operation in mid-November 2010, and since it was put into operation, gasoline refining and processing has been carried out at 100% of the design load, and the sulfur content of the product has always been maintained not more than 50ppm, reaching the national IV standard
.
Five months before the plant was put into operation, the adsorbent consumption was high, the octane number of gasoline was lost, and the loss of benefits was serious
.
Changlian technicians "exposed" the production problems on the internal forum, and the discussion on the forum helped them find the cause of the problem - the high
activity of the adsorbent.
According to this, the technical personnel have adjusted and optimized, so that the indicators of the device have been significantly improved, and the loss of gasoline octane number has been reduced to less than 0.
5, only half of similar devices in China, and this alone has an annual efficiency increase of more than
10 million yuan.
