Compact hydrocarbon wellstream processing

A system for offshore hydrocarbon processing may include a host at surface level, a subsea processing plant, and an umbilical connecting the host and the subsea processing plant. The subsea processing plant may be adapted to receive a multi-phase hydrocarbon stream from a wellhead and to output at l...

More Information
Summary:A system for offshore hydrocarbon processing may include a host at surface level, a subsea processing plant, and an umbilical connecting the host and the subsea processing plant. The subsea processing plant may be adapted to receive a multi-phase hydrocarbon stream from a wellhead and to output at least a hydrocarbon gas-phase stream satisfying a rich gas pipeline transportation specification to a pipeline. The umbilical provides a desiccant for drying the hydrocarbon gas, as well as power and control, from the host to the subsea processing plant.
