Burned tank outlet temperature
Thread Content
If the preheating temperature of the feed oil increases, the reaction temperature will rise; will the outlet temperature of the coking tank also increase?
Generally speaking, there is such a relationship.
Please be more specific. What kind of relationship?
As the preheating temperature of the feed oil increases, the reaction temperature rises as well, and the outlet temperature of the coking tank also increases. As the preheating temperature of the feedstock increases, the heat required for the reaction decreases, and accordingly, the heat of vaporization upon heating the feedstock as well as the reaction heat decrease. So, with no significant change in the amount of charring, the regeneration temperature increases.
As the preheating temperature of the feed oil increases, the reaction temperature rises as well. Due to this increase in reaction temperature, the coking intensity in the coking vessel increases (regardless of whether there is a catalyst circulation tube), and the outlet temperature of the coking vessel goes up. What was mentioned above could lead to an increase in the regenerator bed temperature (in the absence of an external heat exchanger).
However, the reaction temperature is usually set automatically; as the preheating temperature of the feed oil increases, the ratio of catalyst to oil decreases, the degree of reaction decreases, and the amount of coke formed is reduced. Will the outlet temperature of the coking tank rise? Personal opinion
