Abstract
Abstract The associated natural gas produced on crude oil offshore platforms is often flared. The potential of two small-scale Gas-to-Liquids processes to monetise this gas whilst reducing carbon dioxide emissions is investigated in this work. Compact NETmix microreactors are considered for the reactor stages, and the process energy expenditure is reduced through heat integration of endothermic reforming stages, where syngas (a mixture of hydrogen and carbon monoxide) is produced, with exothermic Fischer-Tropsch stages, which convert syngas into liquid fuels. The base concept of the two Gas-to-Liquids processes considered differs mainly on the reforming stage: Steam Methane Reforming or Dry Methane Reforming. The two Gas-to-Liquids routes proposed are compared in terms of capital expenditure, operational expenditure and their emissions reduction potential compared to flaring.
