摘要： Systems and methods for monitoring emissions of a combusted gas are provided. The method includes determining a first net heating value of a flare gas. The method also includes determining a second net heating value of a combustion gas including the flare gas. The second net heating value can be determined based upon the first net heating value and a volumetric flow rate of the flare gas. Based upon the value of the second net heating value, an empirical model or a non-parametric machine learning model can be selected. A combustion efficiency of the combustion gas can be determined using the selected model, the second net heating value, and selected ones of the process conditions and the environmental conditions. Total emissions of the combustion mixture can be further determined from the combustion efficiency and a volumetric flow rate of the combustion gas.

摘要： The present invention relates to a method of controlling a flare gas recovery system, which meets all possible operational scenarios in a primary oil processing plant in a completely continuous, stable and transparent manner for the operator. In particular, the steps performed in the method proposed here include Initialization and Checking the availability of the main compressor, and Monitoring the system inlet pressure and Adjusting the compressor request. More precisely, the method described by the present invention is capable of operating in four operating modes, which comprise: a) a volume accumulation scenario for startup, referring to a system switched on with no compressor yet operating; b) a low burn scenario, referring to a system connected with a single compressor in operation; c) a high burn scenario, referring to a system connected with two compressors in operation; and d) a scenario of high sequential burns, referring to a system connected in “switch mode” between compressors.

摘要： Methods, apparatus, systems, and articles of manufacture are disclosed to measure fallout from a liquid flare burner. An example apparatus includes a device configurator to invoke a first control valve to isolate the liquid flare burner from a test fluid source, and invoke a second control valve to fluidly couple the liquid flare burner to a hydrocarbon source to generate unburned fallout droplets to be captured by first and second measurement surfaces in first and second measurement regions, a parameter calculator to calculate first and second fallout volumes associated with the unburned fallout droplets captured by the first and second measurement surfaces, and determine a fallout efficiency of the liquid flare burner based on the first and second fallout volumes, and a burner configurator to, in response to the fallout efficiency not satisfying a fallout efficiency threshold, adjust a configuration of the liquid flare burner based on the fallout efficiency.

摘要： A flame retarding flare tip, which belongs to the technical field of waste gas treatment resulting from fossil fuel production and aims at solving the technical problem of reducing the appearance of visible and further reducing smoke and gas is provided. According to the flame retarding flare tip, smoked butane, pentane, ethylene, propylene and the like can be subjected to smokeless combustion. Additionally, the flame retarding flare tip can reduce the appearance of visible flames. The invention has the technical scheme that at least a baffling system and at least one tip burner are respectively arranged in parallel in a dual-walled cylinder; the lower end of the cylinder is connected to a flare stack using an adjustable length pipe; an igniter tube is disposed on the portion of the adjustable length pipe that is contained within the cylinder; and a top cover for further preventing the appearance of visible flames and smoke and reduction of toxic gases. The flame retarding flare tip disclosed by the invention is used for treating waste gas resultant from fossil fuel production processes.

摘要： A production stream is received from a well formed in a subterranean formation. The production stream includes a gaseous portion and a liquid portion. The liquid portion has a base sediment and water (BS&W) percentage. At least a portion of the gaseous portion of the production stream is combusted to produce a flaring byproduct stream. The flaring byproduct stream is flowed through a coiled tubing to the well. The BS&W percentage of the liquid portion of the production stream is measured. The flow of the flaring byproduct stream to the well is decreased in response to the BS&W percentage reaching a threshold BS&W percentage.

摘要： Apparatus and method for capturing and combusting all vented natural gas and control natural gases from pneumatic controllers for oil field equipment are described. After an oil or gas well is drilled and completed, separators or treaters, as an example of oil field equipment, are installed on the surface to separate the liquids (oil/condensate and water) and gases (natural gas/methane). Pressure control valves, liquid control valves, temperature control valves, and the like, are pneumatically operated by the natural gas/methane that the separator is processing for sale, when electricity is not available to provide power for these operations. Presently, the pneumatic controllers discharge the pneumatic gas/methane to the atmosphere.
