Flare system using produced water
10443356 · 2019-10-15 · ·

A system and apparatus for treating and disposing of produced water in conjunction with flared gas, thereby avoiding problems associated with injecting produced water back into subsurface strata. The system is installed at or near the wellhead where produced water being treated is at a higher temperatures. Produced water is treated in a scrubber with heat applied through a flare gas field burner, which uses field gas from oilfield operations. A wet scrubber unit with scrubber packing is used to clean emissions. A produced water pump is used to circulate produced water, and pump produced water through spray nozzles in the scrubber unit for use as the wet scrubbing agent. As produced water evaporates, evaporated salts and solids are continuously removed from the evaporator/scrubber unit by appropriate means, such as an auger system. The evaporated salts and solids are then treated via chemical stabilization in a mixing system with chemical reagents to prevent the residual form from being hazardous. The residual material is then stored and disposed of properly.

Flaring boom kit for collecting spills during drilling and workover flaring operations

A flaring boom assembly for a flaring system of a rig is disclosed. The flaring boom assembly includes a tray device comprising an open top, a slanted bottom, and an outlet, and a telescoping mechanism mechanically coupled to the tray device and configured to adjust a relative position of the tray device with respect to a burning head of the flaring system based on a flaring intensity of the flaring system. The spills of the flaring system fall through the open top onto the slanted bottom and move along the slanted bottom toward the outlet based on a gravitational force.

System and Method for Calculating Flare Volumes
20240185268 · 2024-06-06 · ·

A computer-implemented method for calculating an estimated flare volume of natural gas produced from a well is determined as function of reduced volumes sent to a sales line or gathering system. The method includes the steps of determining a baseline static pressure for the gathering system with a static pressure gauge, determining a baseline gas sales rate with a gas sales line flowmeter, identifying a high static pressure event with the static pressure gauge, determining a lost gas sales volume during the high static pressure event, and determining the estimated flare volume as a function of the lost gas sales volume during the high static pressure event.

WELLSITE GREENHOUSE GAS REDUCTION AND HYDROGEN PRODUCTION SYSTEM AND METHOD

A system and a method for reduction or elimination of environmentally harmful or greenhouse gases in situations in which gaseous hydrocarbons are flared or vented from an oil and gas well are disclosed. The system configures to inject a chemically reactive, or dispersive, or reactive and dispersive atomized mist into a gas flow line leading to a flare stack. The mist reacts with the gas in the flow line to convert methane to hydrogen and carbon monoxide and to reduce other harmful gases, facilitating a clean-burning, compact flare of blue color due to the presence of primarily hydrogen, some carbon monoxide, and a small amount of residual methane. The hydrogen and carbon monoxide may be captured and stored before reaching the ignition point at the top of the flare stack.

On demand spark plume generator to ignite flammable gasses
12055290 · 2024-08-06 · ·

A system for a spark plume generator system for igniting flammable gases at a drilling rig includes a support disposed within a fireproof housing proximate to the drilling rig. A grinder is mounted on the support. The grinder includes a rotatable grinder axle with an abrasive grinder surface and an igniter mounted on the support so as to cooperatively contact the grinder. The igniter includes an igniter surface that creates sparks when abraded. The fireproof housing includes an opening. Upon rotation of the grinder axle, the grinder surface abrades the igniter surface to create sparks. The support is positioned within the fireproof housing so that sparks created by the igniter surface exit the fireproof housing through the opening. The fireproof housing is positioned such that the opening is facing the drilling rig and sparks exiting the opening will ignite any flammable gases at the drilling rig.
