Gas dehydration with TEG – triethylenglycol - in offshore units is a frequent choice in the Brazilian gas production and exploration market. Either for transport or re-injection, water must be removed from gas to avoid corrosion and hydrate formation. Offshore units restrictive layout outline process difficulties which must be solved during the engineering and construction phases. Offshore units tend to have vertical orientated layouts while onshore units are spread out horizontally. In floating units equipment location and orientation as well as proper instrumentation selection is crucial Gas dehydration with TEG – triethylenglycol - in offshore units is a frequent choice in the Brazilian gas production and exploration market. Either for transport or re-injection, water must be removed from gas to avoid corrosion and hydrate formation. Offshore units restrictive layout outline process difficulties which must be solved during the engineering and construction phases. Offshore units tend to have vertical orientated layouts while onshore units are spread out horizontally. In floating units equipment location and orientation as well as proper instrumentation selection is crucial due to ocean wave motion. Options such as cooling with sea water are usually an advantage in offshore units, energy recovery and optimization in offshore units is an important factor that must be taken into account. This paper is aimed to share cost effective alternatives for traditional off shore TEG dehydration units.
