Once natural gas liquids (NGLs) have been separated from a natural gas stream, they are further separated into their component parts, or fractions, using a distillation process known as fractionation.
CB&I has designed and built NGL fractionation plants with capacities ranging from 10,000 to 74,000 barrels per day in locations around the world and products include ethane, propane, iso-butane, normal butane and pentanes. We have built both stand-alone fractionation systems, as well as systems integrated with gas processing facilities. Depending on the size of the plant, we can perform some or all of the work utilizing modular construction methods. Modular units are fabricated and preassembled at our fully equipped shops and shipped to the installation site.
