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. In the integrated process, 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 H2. 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 H2. 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. The gaseous hydrocarbon feed supplied to the conversion zone has at least one of the following properties: (i) a sulfur level of at least 25 ppm by volume; (ii) a C02 level of at least 50 ppm by volume; and (iii) a dew point of at least 203°K.
