A+--Best possible selection
A--Recommended
B--Minor to moderate effect. Proceed with caution.
C--Unsatisfactory
I.L.--Information lacking
reduced, the force of the back disk spring causes the
disk to move toward the orice, decreasing the ow of
gas out of the vessel. As vessel pressure drops below
the setpoint of the regulator, the disk will seat against
the orice, shutting off the ow of gas.
Sizing Vapor Recovery Systems
To determine the capacity required, you must consider
the amount of blanketing gas that must be displaced
from the tank when either lling the vessel with liquid
(pump-in) or the expansion of tank vapors during
atmospheric thermal heating.
Using the established procedures from American
Petroleum Institute Standard 2000 (API 2000),
determine the required ow rate for outbreathing.
For liquids with a ash point below 100°F (38°C) or a
normal boiling point below 300°F (149°C), multiply the
calculated outbreathing requirements in Table 6 by 2.0
as indicated in footnote 1 from Table 6.
