1 T205 Series Tank Blanketing Regulators Bulletin 74.1:T205 May 2016 Figure 1. Type T205 Tank Blanketing Regulator Contents Features... 1 Introduction Specifications... 2 Principle of Operation Installation Overpressure Protection Capacity Information Ordering Information Ordering Guide Features Low-pressure setting and fast speed of response T205 Series regulator has a low-pressure setting as low as 1 in. w.c. / 2.5 mbar. It can respond quickly to downstream flow demand and pressure changes due to direct-operated structure. Accurate control and small lockup pressure Large diaphragm area provides very accurate throttling control at low pressure settings. An added benefit of lever style regulator is that it can shut off the process fluid using small lockup pressure. Multiple applications T205 Series regulator can be used for a wide variety of gases including air, nitrogen, natural gas, sour gas (NACE Construction), butane and propane. Corrosion resistance Multiple regulator constructions are available in a variety of materials for compatibility with corrosive process gases. Easy conversion between constructions Converts easily from the Types T205 and T205M to the Types T205H and T205HM with two O-rings and one machine screw. Sour gas service capability Available construction to meet NACE MR D103747X012

Introduction T205 Series tank blanketing regulator is a direct-operated and spring-loaded regulator (Figure 1). The regulator prevents a stored liquid from vaporizing into the atmosphere, reduces liquid combustibility and prevents oxidation or contamination of the product by reducing its exposure to air. T205 Series maintains a slightly positive pressure and thereby reduces the possibility of tank wall collapse during pump out operation. T205 Series is available in two configurations: Types T205 and T205H for internal pressure registration and Types T205M and T205HM for external pressure registration. Principle of Operation T205 Series tank blanketing regulator controls the vapor space pressure over a stored liquid. When liquid is pumped out of the tank or vapors in the tank condense, the pressure in the tank decreases. Tank pressure is sensed by the actuator diaphragm. Spring force pushes the pusher post assembly, the valve disk moves away from the orifice, allowing the gas flow to increase to maintain tank pressure. See Figures 2 and 3. When pressure in the tank increases, the actuator diaphragm is pushed. Through the action of the pusher post assembly, lever and valve stem, the valve disk moves closer to the orifice reducing gas flow. 2

Correction Factors (For converting Air Flow Rates to Other Gas Flow Rates) (1) Blanket gas Specific gravity Correction factor Natural Gas Nitrogen Dry CO For gases of other specific gravities, use equation below Correction Factor = SG Installation The regulator may be installed in any position as long as the flow through the body is in the direction indicated by the arrow on the body when using a T205 Series regulator. To achieve the published capacities at low setpoint, the spring case barrel should be installed pointed down as shown in Figures 2 and 3. For complete actuator drainage, the regulator should be installed as shown in Figure 4. The diaphragm casing may be rotated in order to obtain desired positioning. The Type T205M or T205HM requires a downstream control line. The control line should be installed sloping downward toward the tank to prevent condensation buildup and avoid low points (or traps) that could catch liquid. The sensing line must enter the tank above the liquid level at a point that senses the vapor space pressure and is free from turbulence associated with tank nozzles or vents. Overpressure Protection The T205 Series regulators have an outlet pressure rating lower than or equal their inlet pressure rating. If actual inlet pressure can exceed the outlet pressure rating, outlet overpressure protection is necessary. Refer to the Capacity Information section and the relief sizing coefficients in Table 5 to determine the required relief valve capacity. Universal NACE Compliance Optional materials are available for applications handling sour gases. These constructions comply with the recommendations of National Association of Corrosion Engineers (NACE) sour service standards. The manufacturing processes and materials used by Emerson Process Management Regulator Technologies, Inc. assure that all products specified for sour gas service comply with the chemical, physical and metallurgical requirements of NACE MR Customers have the responsibility to specify correct materials. Environmental limitations may apply and shall be determined by the user. Capacity Information Capacity tables are based on 1.0 specific gravity air. If other blanketing gas is used, convert the tabular values as follows. For blanketing (pad) gases other than air, multiply the given air flow rate by the correction factors in Table 6. For gases of other specific gravities, divide the given air flow rate by the square root of the appropriate specific gravity. where, ΔP Q = C g P 1 SI DEG GT Q = gas flow rate, SCFH G = specific gravity of the gas T = absolute temperature of gas at inlet, Rankine C g = gas sizing coefficient P 1 = absolute inlet pressure, psia C 1 = C g /C v, flow coefficient ΔP = pressure drop across the regulator, psi C 1 P 1 6
