 | Overview of sinopec cangzhou refining and chemical application: Since 2014, the gasoline octane value in the 1.2mt/a catalytic cracking unit of cang zhou refinery has been lower, and the average octane value of the stable gasoline research method has been around 91.35. Due to the low octane number, a certain amount of aromatics need to be purchased to blend, so as to ensure the quality of production, which greatly increases the factory cost of gasoline. Under the circumstance that the process parameters of the device have not been adjusted well for many times, we decided to try our company's xa -1 octane number auxiliary agent to solve the problem of insufficient octane number. l TXA -1 octane number additive was added from March 29, 2014 (blank calibration was carried out before trial). l After two stages of rapid injection and balanced injection, the octane number additive accounted for 3.5% of the system storage. |
Application effect:
After using the catalyst, the yield of gasoline in the catalytic unit decreased by 1.24%, the yield of diesel decreased by 0.92%, but the yield of LPG increased by 2.01%. At the same time, the average octane value of stabilized gasoline increased by 1.12 units. After removing the cost of the catalyst, it is estimated that there will be an annual benefit of nearly 50 million yuan.
