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.

A method for the post-combustion of exhaust gases comprising carbon monoxide from metallurgical processes includes conditioning the exhaust gas prior to post-combustion by metering a combustion gas and/or one additional gas in feedback-controlled fashion. The feedback control depends on the composition of the exhaust gas dependent on the exhaust gas volume flow. A device for post-combustion of exhaust gas during vacuum treatment of liquid steel comprises a flare stack at an exhaust outlet, means for feeding combustion gas to the flare stack, means for feeding an inert gas into the exhaust gas channel of the vacuum pump, means for ascertaining the exhaust gas volume flow and/or for measuring the exhaust gas velocity within the exhaust gas channel, means for analyzing the exhaust gas composition, means for metering the combustion gas and the inert gas, and means for feedback control of the metering of the combustion gas and/or the inert gas dependent on the exhaust gas composition.

An integrated biomass conversion system and a method of starting and shutting down the system are disclosed. The integrated biomass conversion system comprises a syngas generator, such as a gasifier, a cleanup engine and a syngas utilization system, which could be a power producing engine or a chemical reactor for chemical or fuel synthesis. The cleanup engine operates rich and at high temperatures so that the tars exhausted by the syngas generators are destroyed and not allowed to foul other components. An orderly sequence to start and shut down the integrated biomass conversion system is disclosed.

A method may include obtaining first pressure data regarding a first pressure sensor upstream from a restricted orifice and second pressure data regarding a second pressure sensor downstream from the restricted orifice. The method may further include obtaining temperature data regarding a temperature sensor coupled to the restricted orifice. The method may further include obtaining various gas parameters regarding a predetermined gas flowing through the restricted orifice and various orifice parameters regarding the restricted orifice. The method may further include determining a first gas flow rate of the predetermined gas based on a gas flow model, the first pressure data, the second pressure data, the temperature data, the gas parameters, and the orifice parameters.
