Why is the first stage of the vacuum extraction system at the top of the pressure reduction tower called a booster?

I hope an expert can explain the difference between a turbocharger and an evacuator
The booster is installed primarily to overcome the limitation imposed by the saturated vapor pressure of water on the vacuum level at the top of the tower; it functions as a vacuum pump as well. Usually, there is no cooling water before the oil and gas enter the booster, and there is also no atmospheric leg connected to the degasifier tank in front of the booster. The main function of the booster is to increase the pressure of the oil and gas at the top of the tower, so that the pressure at the outlet of the booster is higher than the saturated vapor pressure of water, thereby achieving a higher degree of vacuum.
We’ve learned that we all use extractors; at level three, vacuum pumps are used
If the cooling load downstream is insufficient, it will fail to improve the vacuum level, resulting in unnecessary increased energy consumption
A booster is a first-stage pump; generally, it is a three-stage pump, and three parallel mechanical pumps are used to reduce energy consumption
Generally, a vacuum pump that comes out of the top of the tower without passing through a cooler (either a water cooler or an air cooler) is called a booster
As the name implies, it increases the negative pressure by using pumps. In the past, two or three stages of pumping were sufficient to achieve the desired vacuum level; to obtain an even higher negative pressure, an additional stage was needed, and this was called a booster. Different titles, same essence.
