1. A co-current contact system for operating an absorption column in offshore environments, which comprises:
- a solvent regeneration unit having a rich amine input opening in fluid communication with a rich amine output line connected to the absorption column and a lean amine output line in fluid communication with a lean amine input opening in the absorption column;
a static mixer having a static mixer input opening in fluid communication with the lean amine output line, a treated gas input opening in fluid communication with a treated gas output line connected to the absorption column and a static mixer output line; and
a separator having a separator input opening in fluid communication with the static mixer output line, a separator liquid output line and a separator vapor output line.
