Reaction depth and LPG C5 content
Thread Content
What is the relationship between reaction depth and the C5 content in liquefied gas?
It’s difficult to determine the relationship between the degree of reaction and the C5 content in liquefied gas. When the properties of the feedstock and the catalyst remain unchanged, there is a corresponding relationship between the degree of reaction and temperature: higher temperatures result in a greater degree of reaction, higher gas production rates, a larger absorption capacity, and a higher C5 content in the liquefied gas. Conversely, lower temperatures lead to a lesser degree of cracking, lower gas production rates, a smaller absorption capacity, and a lower C5 content in the liquefied gas. However, the C5 content in liquefied gas is closely related to the operation of stable absorption.
When the processing volume remains constant, a higher reaction temperature results in a higher gas yield, and thus a higher amount of liquefied gas. However, when the temperature is too high, the reaction proceeds more deeply, the amount of dry gas increases, and accordingly the amount of liquefied gas decreases
Personally, I think C5 is only related to stable positions. No connection with other positions
I agree with the view from the 4th floor; as long as it remains within the allowable operating range of the stabilizer tower, the carbon pentane content in the liquefied gas can be kept within the required limits.
The reaction depth has no direct relationship with the C5 content in liquefied gas. With a high reaction depth and high C5 yield, by properly operating the distillation tower, absorption, and stabilization systems, the C5 content in the liquefied gas can be well controlled.
In general, the reaction depth determines the yield of gases and such, which in turn determines the liquid yield； LPG C5 is only related to the operations at the stabilization unit.
Here’s the situation: our company plans to install a new set of catalytic cracking units, provided that there is sufficient funding. How long does it generally take for a new set of equipment to go from design to operation? I’ve just started working in catalysis*, so I’m not very familiar with it; I hope fellow experts can help me out. Thank you
The reaction depth affects the gas yield; greater depth results in more gas production. However, C5 primarily belongs to the gasoline components, and as the reaction depth increases, there is a peak point after which the amount decreases. As for the C5 content in liquefied gas, it is only related to the operation of the stabilizer tower and has little to do with the degree of reaction.
