Once the Natural Gas Liquids (NGL) have been removed from the natural gas stream, it is necessary to break them down into their base components.
This is done by passing them through a series of distillation towers to boil off hydrocarbons starting with the lightest to heaviest. To maximize yields of the most valuable products, fractionation processers need the flexibility to not only handle varying compositions of NGLs but also have the ability to change the mix of hydrocarbon components in the output for sale.
