ABSTRACT:
A tank blanketing system protects both the tank vapor space and the environment. A pad valve supplies inert gas to the vapor space and maintains the pressure in the vapor space under conditions that tend to reduce the pressure in the vapor space. Should the pressure rise a predetermined amount above the setting of the pad valve, a depad valve will open to vent vapors so as to return the pressure in the vapor space to its designed operating range. The depad valve is connected to a recovery piping system that will route the vapors to an appropriate device that processes or disposes of them in a predetermined manner.
