49 results about "Gas flare" patented technology

A gas flare, alternatively known as a flare stack, is a gas combustion device used in industrial plants such as petroleum refineries, chemical plants, natural gas processing plants as well as at oil or gas production sites having oil wells, gas wells, offshore oil and gas rigs and landfills.

Method and apparatus for disposal of well flare gas in oil and gas drilling and recovery operations

A wellhead gas recovery system and method for the generation of power from wellhead gas is provided. A gas conduit is used to direct wellhead gas from a wellhead casing or wellhead bore to a stirling engine where the wellhead gas is used as the fuel source for the stirling engine. The wellhead gas is ignited and the burning wellhead gas is used as the heat source for the stirling engine. The thermal energy from the burning wellhead gas is converted transferred into motion by the stirling engine and the output of the stirling engine can be used to drive devices at the wellsite, generate electricity or other use.

Acetylene tail gas recovery device

The invention relates to an acetylene tail gas recovery device, which belongs to the field of energy conservation and pollution preservation and comprises a tee joint. Three ends of the tee joint are respectively connected with an acetylene tail gas discharge device, an acetylene torch and a first water washing tower. The first water washing tower is connected with a second water washing tower which is connected with a liquid separating fire retarding tower, the liquid separating fire retarding tower is connected with a cracked gas removal compressor inlet, and a cracked gas removal compressor outlet is connected with an extracting and concentrating device. Acetylene tail gas firstly enters the first water washing tower to be carried out preliminary washing, and then enters the second water washing tower to be carried out secondary washing. After two-stage washing of the tail gas, methanal in the tail gas is almost soluble in washing liquid completely, purified tail gas passes through the liquid separating fire retarding tower to be directly sent to an inlet of the cracked gas removal compressor inlet and mixed with pyrolysis gas, and then sent to the extracting and concentrating device after being pressurized by a cracked gas removal compressor, so that recovery and reusing purposes are achieved.
