A fractionation system for removing heavy hydrocarbons in a gas stream. A stripping section receives a predominantly liquid phase of the feed gas stream. A co-current contacting system receives a predominantly vapor phase of the feed gas stream. The co-current contacting system includes a compact contacting bundle disposed within a vessel and including a plurality of substantially parallel contacting units, each of the plurality of contacting units having a droplet generator, a mass transfer section, and a separation system. Each droplet generator generates droplets from a liquid disperses the droplets into a gas stream. Each mass transfer section provides a mixed, two-phase flow having a vapor phase and a liquid phase. Each separation system separates the vapor phase from the liquid phase such that the concentration of heavy hydrocarbons in the vapor phase is lower than in the liquid phase.

Fractionation system using bundled compact co-current contacting systems

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.
