Reduction of CO2 emissions in GTL facility using recovered hydrogen as fuel

摘要

The method relates to reducing CO2 emission from a GTL facility, for example a Fischer-Tropsch process. The method comprises forming syngas by partial oxidation, converting syngas to C3+ hydrocarbons and recovering un-reacted gas, separating the hydrocarbons to produce naphtha, reforming naphtha to produce a by-product hydrogen stream. A hydrogen-rich stream is recovered from either the un-reacted gas or by-product gas and used to produce a hydrogen-rich fuel to feed at least one furnace in a GTL facility to reduce carbon dioxide emissions.
