Conversion of refinery natural purge gases to liquid hydrocarbons in GTL loop with hydrogen-permselective membranes: An alternative to gas flaring

摘要: Abstract One of the main issues facing mankind in this century is global warming which induced by increasing concentration carbon dioxide and other greenhouse gases atmosphere. A promising process for controlling atmospheric CO 2 level prevention combustion flares. In present work, a novel GTL loop proposed to convert natural gas wasted refinery higher molecular weight hydrocarbons. The proposes an alternative method instead conventional - burning flares, aims minimize emissions produce liquid fuel such as gasoline. For purpose, purged converted synthesis hydrogen permselective membrane reactor with recycle stream then it Fischer Tropsch reactor. configuration, constructed returning mixing portion product original feed through stream. This approach produces large amounts hydrocarbons, production decreases environmental impacts owing purge emission. simulation results aforesaid loop, show decrease emission rate value 1/10 that flaring 0.018 kgmol/s more than 90 barrels per day heavy fraction hydrocarbons containing gasoline butane specified (about 4 MMscfd) gases.
