NITROGEN STRIPPING OF A HYDROTREATER CONDENSATE TO FEED A COMBUSTION TURBINE

摘要

A hydrotreated liquid contains volatile hydrocarbons, hydrogen, and contaminants such as hydrogen sulfide. An inert gas, preferably nitrogen, is used to strip volatiles from the hydrotreated liquid. This stripper gas is then added to fuel gas fed to a combustion turbine, where combustibles in the fuel gas and stripper gas are combusted. The stripping is at a pressure sufficient to allow the stripper gas, now containing hydrocarbons and hydrogen, to be added to the combustion turbine fuel without additional compression. This process allows for efficient use of the stripped combustibles, and the nitrogen added to the fuel gas provides increased power generation from the combustion turbine and reduces NOX emissions.
