Abstract
A fractionation system for removing heavy hydrocarbons in a gas stream. A stripping section receives a predominantly liquid phase of a feed gas stream. First and second co-current contacting systems are located in-line within a pipe. The first co-current contacting system receives a predominantly vapor phase of the feed gas stream. Each co-current contacting system includes a co-current contactor and a separation system. Each co-current contactor includes a droplet generator and a mass transfer section. The droplet generator generates droplets from a liquid and disperses the droplets into a gas stream. The mass transfer section provides a mixed, two-phase flow having a vapor phase and a liquid phase. The separation system separates the vapor phase from the liquid phase.
