Abstract: A valve configured to control a flow of a process fluid includes a pair of packing seals separated by a seal gap space along a linear valve stem of the valve, and a pressurization port that can be used to apply a pressurizing fluid, such as nitrogen gas, to the seal gap at a gap pressure that is higher than the process fluid pressure, thereby ensuring that any leakage past the packing seals will be of pressurizing fluid into the process fluid and/or into the environment, and that no process fluid will escape into the environment. The pressure or flow rate of the pressurizing fluid can be monitored to detect and quantify any pressurization fluid leakage past either of the packing seals, so that a maintenance action can be applied to the valve, such as re-tightening or replacing at least one of the packing seals, or replacing the valve.

Abstract: A fuel-gas blending system receives low-pressure tank vapors and high-pressure flash gases from an oil production facility, boosts the pressure of the tank vapors, and blends the tank vapors and high-pressure gases together to supply fuel gas at a pressure and quality required by an onsite fuel-gas-powered generator. The quality of the supplied fuel gas is maintained by controlling the proportion of a high-pressure gas, such as separator gas, in the blend while the volumetric flow rates of the various gases vary in response to the real-time demands of the generator. The system operates in one of multiple modes in order to maximize the use of tank vapors. In one mode, all the gases pass through a low-pressure blower. In another mode, only the tank vapors pass through the blower, and the high-pressure gases are blended with tank vapors downstream of the blower.
