MTBE series: What are the factors that affect the sensitivity temperature of the azeotropic distillation column?

What are the factors that affect the temperature of the sensitivity point in an azeotropic distillation column?
Answer revealed: ① The sensitivity point temperature is the same as that of the entire tower, and it is also affected by the pressure throughout the tower; as pressure increases, the temperature rises, and vice versa. ②Another factor affecting the sensitivity point temperature is the composition of the material inside the tower; too much C5 component will lead to an increase in the sensitivity point temperature. The amounts of isobutylene and MTBE do not affect the sensitivity threshold temperature. ③Effect of the heat source at the bottom of the tower. A higher heating power causes the sensitivity point to shift upward, while a lower heating power causes it to shift downward. Generally, 3 trays are designed at the sensitivity point location to observe changes in its position.
Tower pressure affects temperature, while MTBE purity has an impact as well
Changes in feed composition, feed temperature, top pressure of the tower, and temperature or flow rate of the heat source at the bottom of the tower
