  • Patent number: 9248401
    Abstract: A separator including a vessel, a tray assembly positioned within the vessel, and a wall structure arranged to accumulate a first liquid and a second liquid. A first automatic drain valve is operable to automatically allow liquid accumulated above a first liquid outlet to pass from the vessel in such a way as to maintain a volume of the first liquid above the first automatic drain valve to create a liquid seal over the first automatic drain valve, and a second automatic drain valve is operable to automatically allow liquid accumulated above the level of an open upper end of the wall structure to pass from the vessel in such a way as to maintain a volume of the second liquid above the second automatic drain valve to create a liquid seal over the second automatic drain valve.

  • Patent number: 7981200
    Abstract: A flare stack that preferably comprises a burner assembly, an exhaust stack, an housing, and a fuel line. The burner assembly burns a fuel to generate thermal energy and combustion byproducts. The exhaust stack is cooperatively associated with the burner assembly to direct the thermal energy and combustion byproducts away from the burner assembly. The housing at least partially defines a fluid-receiving chamber in thermal communication with the exhaust stack. The fluid-receiving chamber has a heat-transfer fluid disposed therein. The fuel line is in fluid communication with the burner assembly to deliver fuel to the burner assembly. At least a portion of the fuel line is in thermal communication with at least one of the exhaust stack, housing, or heat-transfer fluid to permit fuel in the fuel line to absorb thermal energy before reaching the burner assembly.
