The Pearl GTL is a gas to liquids (GTL) plant based in Ras Laffan, Qatar. It converts natural gas into liquid petroleum products. It is the largest GTL plant in the world.[1][2] PThe first commercial shipment from the Pearl GTL was made on 13 June 2011.[3]

When achieving the full capacity in 2012, the Pearl GTL will convert 1.6 billion cubic feet per day (45×106 m3/d) of natural gas into 140 thousand barrels per day (22×103 m3/d) of petroleum liquids and 120 kilo barrels of oil equivalent (730 TJ) into natural gas liquids and ethane. The integrated process automation and control system for the main plant and the onplot tank farm will be designed and implemented by Honeywell, while that for the offplot tank farm and the loading berths will be designed and implemented by Invensys. Page Europa was contracted as overall Telecom System Integrator for both onshore and offshore telecommunications systems. ABB Group was contracted to supply all of the electrical and control systems. The first train will be commissioned in 2010, followed by the second train in 2011.[4][5]
The main contractors are KBR and JGC Corporation. Other contractors are J. Ray McDermott, CB&I, Consolidated Contractors Company and Descon Engineering Limited.[1] The process pumps aree supplied by Flowserve, chemical injection pumps are by LEWA Germany and eight turbomachinery trains for use in the air separation systems are supplied by Linde. Six reactors for the Fischer-Tropsch process are supplied by MAN AG.[5][6]
The Pearl GTL project builds upon the foundations of the smaller scale GTL project in Bintulu, Malaysia, which has been in operation since 1993.[7] The plant is expected to reach full production in mid-2012.[8]
In 2003, the project cost was estimated to be US$5 billion. However, after facing huge cost escalation, it was reported to be $18 billion in 2007,[1] and, according to Qatar Petroleum sources, final project cost is expected to reach as high as $24 billion.[9] Because Shell's contract provided them with the input gas for free, the project was calculated to be viable once the price of oil exceeded $40.[10]
The project is a Production Sharing Agreement (PSA) between Qatar Petroleum and Shell.
The primary products of the Pearl GTL plant is naphtha and transport fuels, with paraffins and lubricant oils as smaller by-products of the process. The transport fuel can be used in existing light and heavy diesel engines and has been shown to have a number of benefits, such as lower emissions and engine performance enhancement.[11]
