18. n maintains a higher loading pressure on the bottom of the Type 1098 actuator The pressure differential across the main valve diaphragm moves the diaphragm upward causing the main valve to open which allows the blanket gas to flow out to the vapor recovery system vacuum source hence controlling the vessel blanket pressure When the vessel blanket gas pressure begins to stabilize the pilot spring throttles the pilot disk closed This allows the loading pressure source to fill both sides of the Type 1098 actuator through the fixed restriction This equalizes the pressure acting on the diaphragm thus allowing the main valve spring to close the main valve plug Sizing Blanketing Systems When sizing a gas vapor recovery regulator system you must consider the volume of blanketing gas that must be displaced from the vessel when either filling the vessel with liquid pump in or the expansion of vapors inside the vessel during atmospheric thermal heating Using the established procedures from American Petroleum Institute Standard 2000 API 2000 determine the flow rate for outbreathing 1 Determine the flow rate of blanketing gas displaced when liquid is being pumped into the vessel see Table 6 2 Determine the gas flow rate due to outbreathing caused by atmospheric thermal heating see Table 7 3 Add the requirements of 1 and 2 and select a vapor recovery regulator size based on total capacity required from Table 4 Sample
