1. A process for converting aromatic hydrocarbons from accompanying gas in which a stream coming from the reaction zone and comprising hydrogen, C1-C4 alkanes and aromatic hydrocarbons C6+is fed to a separation zone, an effluent vapor stream is withdrawn from the separation zone which comprises hydrogen and methane, and a liquid stream I of the process comprising propane, butane and C6+ aromatic hydrocarbons feed I stream in the fractionation zone and separate it into at least II stream of the process comprising propane and butane and I stream of products comprising C6+ aromatic hydrocarbons, said II stream of products is fed to a reaction zone of dehydrocyclodimerization, operated under dehydrocyclodimerization conditions, and producing a stream withdrawing from the reaction zone, characterized in that vapor phase stream from the separation zone comprises also ethane and raw gas comprising C1-C4 alkanes and a part of the vapor stream from the separation zone to the reaction zone. 2. The process according to claim 1, characterized in that II stream of products is separated in the fractionation zone and withdrawn from the process. 3. The process according to claim 1, characterized in that raw gas also comprises C5+ and C1-C4 alkanes which are separated from raw gas in the fractionation zone in II stream of the process and withdraw I stream of products comprising also C5+ hydrocarbons containing in raw gas. |
