SYSTEM AND METHOD FOR PROCESSING NATURAL GAS PRODUCED FROM A SUBSEA WELL

摘要

A system and method for processing natural gas produced from a subsea well is disclosed. The system includes a subsea processing system configured, in use, to receive a natural gas produced from a subsea well, separate free and condensable liquids comprising water and, optionally, liquid hydrocarbons therefrom, and produce a dry single phase gas. The system also includes a surface production facility having a processing system located thereon for processing the free and condensable liquids separated in the subsea processing system and one or more risers for transporting the separated free and condensable liquids to the processing system on the surface production facility. The dry single phase gas produced in the subsea processing system is transported to an onshore production facility via a subsea pipeline. The subsea processing system operates at high pressure and the processing system on the surface production facility operates at low pressure. Hydrocarbon liquids processed on the surface production facility may be combined with the dry single phase gas to produce a dry dense phase for transport via the subsea pipeline.
