An electronically controlled burner management system for oilfield separators. The system includes an autonomous standing pilot spark ignition that includes a self-aligning clamp that holds the igniter to the burner nozzle. The self-aligning clamp enables rapid installation and removal, lowering the total cost of ownership. The autonomous spark ignition system incorporates temperature sensors to determine when the standing pilot needs to be relit, and can shut off the gas or other fuel flow to the standing pilot and the main burner when the pilot is not lit. The system increases oil and gas production from the well, reduces fugitive emissions of unburned gas, and improves oilfield worker safety. When installed or retrofitted into an existing oilfield separator, the original burner control components are left in place, allowing the user to revert to traditional operation in case of failure of any electronic component of the present system.

A compact and portable liquid concentrator includes a gas inlet, a gas exit and a flow corridor connecting the gas inlet and the gas exit, wherein the flow corridor includes a narrowed portion that accelerates the gas through the flow corridor. A liquid inlet injects liquid into the gas stream at a point prior to the narrowed portion so that the gas-liquid mixture is thoroughly mixed within the flow corridor, causing a portion of the liquid to be evaporated. A demister or fluid scrubber downstream of the narrowed portion removes entrained liquid droplets from the gas stream and re-circulates the removed liquid to the liquid inlet through a re-circulating circuit. Fresh liquid to be concentrated is also introduced into the re-circulating circuit at a rate sufficient to offset the amount of liquid evaporated in the flow corridor.

A thermal oxidizer (50) employing an oxidation mixer (51), an oxidation chamber (52), a retention chamber (53) and a heat dissipater (54) forming a fluid flow path for thermal oxidation of a waste gas. In operation, the oxidation mixer (51) facilitates a combustible mixture of the waste gas and an oxidant into an combustible waste gas stream. A heating element (55) of the oxidation chamber (52) facilitates a primary combustion reaction of the combustible waste gas stream into an oxygenated waste gas stream. The retention chamber (53) facilitates a secondary combustion reaction of the oxygenated waste gas stream into oxidized gases. The heat dissipater (54) atmospherically vents of the oxidized gases. An oxidization controller (61) may be employed to regulate the operation of the thermal oxidizer (50), and a data logger (63) and a data reporter (65) may be employed for respectively logging and remotely reporting a regulation of the thermal oxidizer (50) by the oxidation controller (61).

A system for use with a fired vessel of production/separators or dehydration equipment that includes a metal box, a main burner, a pilot burner, and a flame arrestor. The main burner and the pilot burner are within the metal box and the first flame arrestor is connected to the metal box.

A wastewater container, or fluid capture tank, for capturing fluid from a flare is provided, along with methods for making and using the fluid capture tank. The fluid capture tank includes an open top tank to hold fluid for disposal, and a flare chute mounted to one end of the open top tank. The flare chute includes three panels, including a bottom panel mounted to a left wall panel and a right wall panel, wherein the three panels direct fluid from a line into the open top tank. A refractory lining is disposed on an inner surface of at least one of the three panels facing the line, wherein the refractory lining protects the inner surface from heat as hydrocarbons in the fluid are burned.

Pilot assemblies comprising a fire path tubing and pilot tubing in fluid communication through a pilot nozzle for elevated flare stacks are disclosed. A plurality of flame segments is generated using a hot surface ignition element or a spark igniter in the fire path tubing and ignites fuel/air mixture flowing through the pilot tubing into a pilot nozzle to produce a reliable pilot flame. The pilot flame ignites the waste gases flowing out of the flare tip of elevated flare stacks. Methods for operating the pilot assemblies are also disclosed.

A liquid seal mating system to accommodate thermal expansion during elevated-temperature operation, including a collar, sized and shaped to receive a discharge end of a gas-delivery conduit and a fence that surrounds the collar and is attached thereto, wherein when installed, the collar accommodates thermal expansion of the gas-delivery conduit along a longitudinal axis of the gas-delivery conduit and limits movement of the gas-delivery conduit perpendicular to the longitudinal axis. A method for suppressing bulk fluid motion in an elevated-temperature liquid seal, including attaching a mount to an outer shell of a liquid seal and receiving, within a mating collar, a discharge end of a gas-delivery conduit, the mating collar attached to the mount and being sized and shaped to accommodate thermal expansion of the gas-delivery conduit, filling the outer shell with liquid to submerge the discharge end of the gas-delivery conduit, and flowing gas through the gas-delivery conduit.

A combustor having a rectangular prism structure with a burner assembly mounted inside for burning waste hydrocarbon gases with combustion air provided through flame arrestors from outside atmospheric air, the combusted hydrocarbon gas exiting through an opening on top of the structure. The combustor includes a controller for operating an igniter on the burner assembly and thermocouples for measuring the temperature of exhaust gas exiting the combustor and for measuring the skin temperature of the structure. The controller can relay the operational data and the location of the combustor to a central control center through a SCADA unit connected to a telecommunications network. The controller can also relay the volume of waste gas burned to the central control center to determine the carbon credits earned by preventing the waste gas being vented to the atmosphere.

A flame arrester/burner assembly with a multifarious arrester element for preventing deflagrations and extended endurance burning time (FABA-XT). The multifarious element flame arrester includes a pipe body having a first end and a second end, a first arrester element positioned within the pipe body adjacent the top end; a third arrester element adjacent the bottom end; and, a second arrester element positioned in the pipe body between the first arrester element and the second arrester element. The first, second, and/or third arrester elements may be of the same design or disparate designs. The FABA-XT of the present disclosure is an end-of-line burner element for use in VOC-Vapor Destruction Systems.

A system for use with a fired vessel of production/separators or dehydration equipment that includes a metal box, a main burner, a pilot burner, and a flame arrestor. The main burner and the pilot burner are within the metal box and the first flame arrestor is connected to the metal box.
