Abstract
An integrated process for producing LNG and GTL products is provided, wherein a CO2-containing natural gas feed to an LNG production zone is first pre-treated to separate at least a portion of the CO2 therefrom, and the resulting CO2 stream obtained thereby is then directed to a GTL production zone and utilized to make GTL products that include methanol and/or methanol derivatives.

An integrated process for producing LNG products in a LNG Phase production zone and conversion of natural gas into GTL products that include methanol in a GTL Phase production zone from a natural gas comprising hydrocarbons and CO2, the process comprising the steps of:
- pre-treating at least a first portion of the natural gas to separate at least a portion of the CO2 therefrom and produce a natural gas feed having reduced CO2 content and a stream rich in CO2;
- converting the natural gas feed into an LNG product in the LNG Phase;
- converting a second portion of the natural gas to a synthesis gas by steam methane reformation;
- and
- reacting the stream rich in CO2 with at least a portion of the synthesis gas in the GTL Phase to produce methanol.

- pre-treating at least a first portion of the natural gas to separate at least a portion of the CO2 therefrom and produce a natural gas feed having reduced CO2 content and a stream rich in CO2;
- converting the natural gas feed into at least one natural gas vapor component and an LNG product in the LNG Phase;
- converting the at least one natural gas vapor component, and optionally a second portion of the natural gas, to a synthesis gas by steam methane reformation;
- and
- reacting the stream rich in CO2 with at least a portion of the synthesis gas in the GTL Phase to produce methanol.
