Dehydration

Drying and removal of water, setting of water dew point

- In connection with free water natural gas is prone to form gas hydrates that may block pipelines and equipment.

- Free water leads to corrosion, particularly in the presence of sour components such as CO2 and H2S.p 2 2

- Water can condense in the pipeline and accumulates at low points, thus causing corrosion.p , g

Condensate Separation

Reasons for separating higher hydrocarbons from natural gas:

- Conditioning of gas for pipeline transport

- Setting of the hydrocarbon dew point based on the specification for ll blsellable gas

- Production of Natural Gas Liquids (NGL) as sellable product (propane butane)(propane, butane)



Condensate Separation Technologies

Temperature setback (of dry raw gas) by

- Chilling unit: e. g. propane chilling unit; if required, b t d t f ti tisubsequent condensate fractionation

- JOULE-THOMSON effect: by expansion valve (disadvantage: loss of energy!)gy )

- Turboexpander: cooling of the gas by expansion,use of expansion energy to drive the natural gas compressor

If required: compression to pipeline conditions; ethane separation from condensate.
