In the catalytic cracking stabilization unit, why is the dry point of crude gasoline always higher than that of stabilized gasoline?

It is well known to those who have worked with catalytic processes that the dry point of crude gasoline is always higher than that of refined gasoline. But why is that? I believe many people can’t explain it either! Welcome to theoretical skills? A knowledgeable friend shares their insights. After different components are mixed together, the intermolecular forces within them change, which leads to variations in the boiling range. The broad boiling range of crude gasoline is due to the influence of liquefied gas components such as C4; these components facilitate the evaporation of lighter fractions, while the heavier fractions have difficulty evaporating because of the reduced presence of lighter components, resulting in an increase in the dry point of crude gasoline ； Stabilized gasoline lacks gases with molecular weights below C4; the bonding force between light components and heavy components is stronger, which has a significant impact on the heavy components, increasing their evaporation capacity. As a result, the dry point of stabilized gasoline decreases. Please correct any metaphorical expressions used. 2. If the C4 content in crude gasoline is higher than that in stabilized gasoline, then it should be the stabilized gasoline that is used as the rich gas absorbent, rather than the crude gasoline. In fact, the opposite is true: crude oil is used as the absorbent, while stabilizing vapor is used only as a supplement. Stable gasoline is produced as a product and is used in large quantities to absorb liquefied gas; how is it then manufactured? Here is my personal understanding
