ulletin 74.:90 November 205 Type 90 LowPressure Tank lanketing Regulator Figure. Type 90 Tank lanketing Regulator Introduction The Type 90 lowpressure tank blanketing regulator is used for extremely accurate pressure control on very lowpressure blanketing systems. The regulator helps to control emissions and provides protection against any contamination from atmospheric conditions by providing a flushing action. The Type 90 tank blanketing regulator maintains a positive vessel pressure thereby reducing the possibility of vessel wall collapse during pumpout operations. Type 90 lowpressure tank blanketing regulator reduces a highpressure gas, such as Nitrogen, to maintain a protective environment above any liquid stored in a tank or vessel while the liquid is being pumped out. lso, when the vessel cools suddenly causing the vapors inside the vessel to condense, the tank blanketing regulator replaces the condensed vapors with the blanketing gas to prevent the internal vessel pressure from decreasing. In both cases, a slight positive vessel pressure prevents outside air, moisture and other contaminants from entering the vessel and the possible collapse of the vessel walls. Features Quickhange Trim Package Tested trim packages can be made up and stocked ahead of time for fast replacement. InService Travel Inspection Standard indicator assembly with protective cover permits periodic inspection of plug travel without removing regulators from service. Easy InLine Maintenance Topentry design reduces maintenance time and manpower requirements; trim parts can be inspected, cleaned and replaced without removing the main valve body from the pipeline. FactoryPiped Pilot Supply Supply pressure to pilot is supplied from inlet side of the main valve body through tubing furnished with the regulator. D0962X02 www.fisherregulators.com

Operational Schematic Principle of Operation The Type 90 tank blanketing regulator reduces a highpressure inert gas to maintain a positive lowpressure of blanket gas over a stored liquid while liquid is being pumped out of the tank. lso, when the tank suddenly cools causing tank vapors to condense, the Type 90 regulator replaces the condensing vapors with an inert gas to prevent the internal tank pressure from decreasing. In both cases, a positive tank pressure prevents outside air from entering the vessel preventing contamination and reducing the possibility of atmospheric pressure collapsing the vessel. The Type 90 regulator is pilotoperated. It responds to slight decreases in internal tank pressure by throttling open to increase the flow rate of inert gas into the vessel. When the vessel s liquid level has been lowered to the desired point and the vapor pressure reestablished, the Type 90 regulator throttles closed. The Type 90 regulator utilizes a Type 098EGR main valve actuator (Type EGR main valve and Type 098 actuator), a Type T205P sensing pilot and a Type MR95H supply pressure regulator. The Type T205P pilot uses the highpressure inlet gas, reduced by a Type MR95H supply pressure regulator, as loading pressure to operate the Type 098EGR main valve actuator. The outlet or vessel pressure is sensed through a control line on the Type 098EGR main valve actuator and also on the Type T205P pilot diaphragm. When the liquid level is decreased and vessel pressure decreases below the pilot control spring setting, the pilot spring force on the pilot diaphragm opens the pilot valve plug, allowing additional loading pressure to the main valve actuator diaphragm. The loading pressure opens the main valve plug to supply the required flow of gas to the vessel. When downstream demand has been satisfied, outlet pressure tends to increase slightly, acting on the pilot and main valve diaphragms. When the outlet pressure exceeds the pilot control spring setting, the pilot diaphragm moves to close the pilot valve plug. The loading pressure reduces by exhausting downstream through the fixed restriction, allowing the Type EGR main valve spring to close the Type EGR main valve plug. The combination of Type EGR main valve spring force and Type EGR main valve plug unbalance provides positive shutoff of the valve plug. 4

Flows are in SFH (at 60 F and 4.7 psia) and Nm 3 /h (at 0 and.0325 bar) of 0.97 specific gravity Nitrogen. For gases of other specific gravities, multiply the given capacity of Nitrogen by 0.985, and divide by the square root of the appropriate specific gravity of the gas required. To determine wideopen flow capacities for relief sizing, use the following formula: where, = g / v or 35 as shown in Table 8 g = gas sizing coefficient from Table 8 G = gas specific gravity (air = ) = inlet pressure, psia (psig + 4.7 psi = psia) P = pressure drop across the regulator, psi (P P 2 ) Q = gas flow rate, SFH T = absolute gas temperature at inlet, Rankine P 2 = outlet pressure, psig P abs Q = 520 GT g P abs SIN 347 P P DEG Monel is a mark owned by Special Metals orporation.

Using procedures such as those established by the merican Petroleum Institute Standard 2000 (PI 2000), determine the flow of blanketing gas required.. Determine the gas flow rate required to replace the liquid being pumped out (see Table 6). 2. Determine the gas flow rate due to inbreathing caused by atmospheric thermal cooling (see Table 7). 3. dd results from steps and 2, then select regulator size, based on total capacity required (see Table 0). Sample sizing problem: Vessel apacity... 50,000 barrels Pump In/Out apacity... 00 GPM / 378 LPM Inlet Pressure Source... 60 psig / 4. bar of Nitrogen Desired lanket Setpoint... 0.5 in. w.c. /.2 mbar. From Table 6 the desired air flow rate due to pumpout is 800 SFH / 2 Nm 3 /h of air (00 GPM / 378 LPM x 8.02 = 802). 2. From Table 7 the desired air flow rate is 40,000 SFH / 072 Nm 3 /h of air due to thermal cooling. Total required flow rate of 40,800 SFH / 093 Nm 3 /h of air converts to 4,600 SFH / 5 Nm 3 /h of Nitrogen (40,800 x.08 = 4,534). 3. From Table 0, an NPS / DN 25 body size would flow 45,500 SFH / 29 Nm 3 /h of Nitrogen at 60 psig / 4. bar inlet pressure. This would satisfy the desired flow rate of 4,600 SFH / 5 Nm 3 /h of Nitrogen. 8

If a block valve is required, install a full flow valve between the regulator and the blanketed vessel. For proper operation at low set point ranges, the regulator should be installed with the pilot spring case barrel pointed down.
