The present techniques are directed to a flexible liquefied natural gas (LNG) plant that may be tied to an external electric grid for importing or exporting electric power. Exemplary embodiments provide a method for producing LNG that includes producing a base load capacity of refrigeration capacity for LNG production from a first compression system. Electricity may be produced from a second compressor string if electricity is needed by an external power grid, or a second amount of refrigeration capacity may be provided by the second compressor string is natural gas feed is available and the external grid does not need power.

Flexible liquefied natural gas plant

A process for converting a gaseous hydrocarbon feed comprising methane to an aromatic hydrocarbon is integrated with liquefied natural gas (LNG) and/or pipeline gas production. The gaseous hydrocarbon feed is supplied to a conversion zone comprising at least one dehydroaromatization catalyst and is contacted with the catalyst under conversion conditions to produce a gaseous effluent stream comprising at least one aromatic compound, unreacted methane and H. The gaseous effluent stream is then separated into a first product stream comprising said at least one aromatic compound and a second product stream comprising unreacted methane and H. The second product stream is further separated into a methane-rich stream and a hydrogen-rich stream and at least part of the methane-rich stream is passed to LNG and/or pipeline gas production.

Methane conversion process

The invention relates to the integration of a dehydroaromatization process with the processes for the utilization of associated gas; gases comprising methane and higher hydrocarbons, and/or liquefied natural gas (LNG) production or usage.
