EPC Contractors Engineering Procurement Construction

Construction of the world’s largest gas to liquids (GTL) plant, Pearl GTL in Qatar, is a major step towards meeting the world’s growing demand for cleaner energy.
The drive is on to make tomorrow’s transport fuels and lubricants on a large scale from clean-burning natural gas. Construction of the world’s largest gas to liquids (GTL) plant, Pearl GTL in Qatar, is a major step towards meeting the world’s growing demand for cleaner energy.
The plant, a joint development by Qatar Petroleum and Shell, will process about three billion barrels-of-oil-equivalent over its lifetime from the world’s largest single non-associated gas field, the North Field, which stretches from Qatar’s coast out into the Gulf. The North Field contains more than 900 trillion cubic feet of gas, about 15% of worldwide gas resources.
Pearl GTL will produce cleaner-burning diesel and kerosene, base oils for top-tier lubricants, a chemical feedstock called naphtha, which is used to make plastics, and normal paraffin, which is used to produce detergents.
It will produce enough fuel to fill over 160,000 cars a day and enough synthetic base oil each year to make lubricants for more than 225 million cars.
