Reaction system feed temperature
Thread Content
What is the basis for selecting the feed temperature in the reaction system? What’s the temperature usually? What are the effects of being too high or too low?
Meet the temperature requirements of the catalyst for pretreatments such as demetallization.
The catalyst is static, but the raw materials are changing constantly; there are slight differences in density and flow rates within the same raw material tank. Raw materials have a significant impact on the reactor inlet temperature; I have gained a deep understanding of this due to the complex nature of raw materials in private refineries. The temperature is generally controlled at 300~330°C. An insufficient amount of hydrogenation agent fails to remove elements such as sulfur and nitrogen; this can result in substandard oil quality at the least, or damage to the refining equipment at the worst. The temperature at the rear section of the reactor is difficult to control; in mild cases this affects the yield, while in severe cases it can lead to excessive temperatures that result in the catalyst becoming unusable.
