Do Class A liquefied hydrocarbons require a pressure booster? Is Class A B substances like hexene-1 not needed? Liquefied propylene is needed! Why? Thank you
Help explain why a booster is needed, what are the reasons for boosting, and which media require a booster? Thank you, I will repay you generously!
It should be determined based on the physicochemical properties of the medium itself, right? ? ? Just participate blindly; don’t mind it, haha:lol
I am also unfamiliar with boosters, but for liquefied hydrocarbons, different saturation pressures correspond to different saturation temperatures; when the pressure is too low, the temperature is also very low. If the material of the storage tank is not resistant to low temperatures, it may crack.
In general design, low ambient temperatures are taken into account; when the liquid level drops, the pump may experience cavitation issues. Therefore, vaporization facilities are added to increase the gas phase pressure in the storage tank, ensuring an adequate net positive suction head for the pump.
The propylene storage tank is equipped with a vaporizer; in winter, it is used to replenish pressure in the propylene tank’s feed tank and increase the gas phase pressure within the storage tank
The first factor in deciding on a booster is its tank type; pressure tanks (spherical tanks) are necessary, while atmospheric tanks are not; Secondly, it needs to be determined based on the inflow and outflow of materials in the spherical tank and the local climate. If the local ambient temperature is low, vaporization may not occur promptly in winter; in such cases, a booster (vaporizer) needs to be installed ; Then, check whether your pump will experience cavitation ; Finally, it depends on the material of your storage tank; if it can withstand low temperatures, it is generally not necessary.
