Gas Treatment facilities on offshore platforms generally contain glycol systems for gas dehydration. These systems have a number of commonly encountered problems that reduce efficiency, stability or uptime. These can usually be solved quickly.
NGL recovery, cold plants and H2S removal (such as amine) systems are less common systems offshore although they can be problematical. This is usually due to the highly energy efficient or "looping" design that makes the plant interactive and sensitive to control.
