Figure 1. Type 1190 Low-Pressure Gas Blanketing Regulator

Introduction

The Type 1190 low-pressure gas blanketing regulator is used for extremely accurate pressure control on very low-pressure blanketing systems. The regulator helps to control emissions and provides protection against any contamination from atmospheric conditions

by providing a ushing action. The Type 1190 gas

blanketing regulator maintains a positive vessel pressure thereby reducing the possibility of vessel wall collapse during pump-out operations.

A Type 1190 low-pressure gas blanketing regulator reduces a high-pressure 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. Also, when the vessel cools suddenly causing the vapors inside the vessel to condense, the gas 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

• Quick-Change Trim Package—Tested trim

packages can be made up and stocked ahead of time for fast replacement.

• In-Service Travel Inspection—Standard indicator assembly with protective cover permits periodic inspection of plug travel without removing regulators from service.

• Easy In-Line Maintenance—Top-entry design reduces maintenance time and manpower requirements; trim parts can be inspected, cleaned, and replaced without removing the main valve body from the pipeline.

• Factory-Piped Pilot Supply—Supply pressure to pilot is supplied from inlet side of the main valve body through tubing furnished with the regulator.

Principle of Operation

The Type 1190 gas blanketing regulator reduces a high-pressure inert gas to maintain a positive low-pressure of blanket gas over a stored liquid while liquid is being pumped out of the tank. Also, when the tank suddenly cools causing tank vapors to condense, the Type 1190 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 1190 regulator is pilot-operated. It responds to slight decreases in internal tank pressure by throttling

open to increase the ow rate of inert gas into the vessel.

When the vessel’s liquid level has been lowered to the desired point and the vapor pressure re-established, the Type 1190 regulator throttles closed.

GAS BLANKETING

PRESSURE

The Type 1190 regulator utilizes a Type 1098-EGR main valve actuator (Type EGR main valve and Type 1098 actuator), a Type Y191A sensing pilot, and a Type 95H supply pressure regulator. The Type Y191A pilot uses the high-pressure inlet gas, reduced by a Type 95H supply pressure regulator, as loading pressure to operate the Type 1098-EGR main valve actuator. The outlet or vessel pressure is sensed through a control line on the Type 1098-EGR main valve actuator and also on the Type Y191A 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 ow of gas to the vessel.

When downstream demand has been satised, 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 xed restriction, allowing the main valve

spring to close the main valve plug. The combination of main valve spring force and main valve plug unbalance provides positive shutoff of the valve plug.

Sizing Blanketing Systems

When sizing a gas blanketing regulator for a lowpressure blanketing application, you must consider the replacement of blanketing gas required for the liquid loss during pump out of the vessel plus the condensation and contraction of the vessel vapors during atmospheric thermal cooling.

Using procedures such as those established by the American Petroleum Institute Standard 2000 (API 2000),

determine the ow of blanketing gas required.

1. Determine the gas ow rate required to replace the liquid being pumped out (see Table 6).

2. Determine the gas ow rate due to “inbreathing” caused by atmospheric thermal cooling (see Table 7).

3. Add results from steps 1 and 2, then select regulator size, based on total capacity required (see Table 10).

Sample sizing problem:

Vessel Capacity ................... 50,000 barrels

Pump In/Out Capacity ............. 100 GPM / 378 LPM

Inlet Pressure Source ... 60 psig / 4.1 bar of Nitrogen Desired Blanket Setpoint ... 0.5 inch w.c. / 1.2 mbar

1. From Table 6 the desired air ow rate due to pump-out is 800 SCFH / 21 Nm3/h of air (100 GPM / 378 LPM x 8.021 = 802).

2. From Table 7 the desired air ow rate is 40,000 SCFH / 1072 Nm3/h of air due to thermal cooling. Total required ow rate of 40,800 SCFH / 1093 Nm3/h of air converts to 41,600 SCFH / 1115 Nm3/h of Nitrogen (40,800 x 1.018 = 41,534).

1. To obtain Nm3/h, multiply SCFH by 0.0268.

3. From Table 10, an NPS 1 / DN 25 body size would ow 45,500 SCFH / 1219 Nm3/h of Nitrogen at 60 psig / 4.1 bar inlet pressure. This would satisfy the desired ow rate of 41,600 SCFH / 1115 Nm3/h of Nitrogen.
