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

Integrated processing of natural gas into liquid products

An integrated process for producing LNG and GTL products is provided comprising cooling natural gas in at least one cooling step so as to provide a cooled natural gas stream; processing the cooled natural gas stream in at least two expansion/separation cycles, each expansion/separation cycle comprising the Substeps of (a) isentropically or isenthalpically expanding at least a portion of the cooled natural gas steam for producing a natural gas vapor component and a LNG component, (b) separating at least a portion of the natural gas vapor component from the LNG component, and (c) repeating substeps (a) through (b) wherein at least a portion of the LNG component from the previous expansion/separation cycle is directed to each successive Substep (a) and wherein the final LNG product is the LNG component after the final separating step and is substantially liquid at substantially atmospheric pressure; and converting at least a portion of one or more of the expansion/separation cycle natural gas vapor components into a GTL product.

A method of generating power by passing a dimethyl ether-containing fuel to a dry low NO,combustor of a fired turbine-combustor in the presence of an oxygen-containing gas for combustion in the combustor to form flue gas, and then passing the flue gas to the turbine to generate power, wherein the fuel comprises a mixture of dimethyl ether, at least one alcohol and, optionally, a component selected from the group consisting of water and C,-C,alkanes. The fuel composition used in the inventive method permits a safe and highly efficient operation of a dry low NO,combustion system, while at the same time, minimizing the generation of NO,and carbon monoxide emissions.
