Ceyhan (pronounced [dʒeːˈhan]) is a city in southern Turkey and with 105,000 (2010) inhabitants (150,000 in the metropolitan area) it is the second largest city of Adana Province after the capital Adana. Ceyhan is the transportation hub for Middle Eastern, Central Asian and Russian oil and natural gas. It is situated on the Ceyhan River, from which it takes its name, in central Çukurova, 43 km (27 mi) east of Adana. The Ceyhan River is dammed at Aslantas to provide flood control and irrigation for the lower river basin around Ceyhan.
Ceyhan's marine transport terminal is the Mediterranean terminus of the Baku–Tbilisi–Ceyhan pipeline (the "BTC") which brings crude oil from the landlocked Caspian Sea across Azerbaijan and Georgia, and entering Turkey in the northeast. The pipeline was completed in May 2005. The terminal contains seven storage tanks, a jetty capable of loading two tankers of up to 300,000 metric tons deadweight (DWT) simultaneously, metering facilities, a waste water treatment plant and vapor incineration ("burn-off") facilities.
Ceyhan Terminal is also the destination of Kirkuk-Ceyhan Oil Pipeline and planned Samsun-Ceyhan by-pass pipeline. In future Ceyhan will be also a natural gas hub for a planned pipeline constructed parallel to the Kirkuk-Ceyhan oil pipeline, and for a planned extension of the Blue Stream Gas Pipeline to from Samsun to Ceyhan.
Set to become a crossroad in the near future, Ceyhan's significance in political terms is also expected to rise considerably, as stressed during an early 2006 symposium organized by the municipality.
Ceyhan is the second most developed and populated city of Adana Province after Adana. Like everywhere else on this coast it is roasting hot in summer. There are a number of restaurants serving the legendary Adana kebab. The river runs through the city center.
