SORDECO Process by Shell
The SORDECO process applies Sorbead adsorbent beads packed into an adsorber column. It selectively removes water (H2O) and hydrocarbons from natural gas. When the adsorbent is saturated, stripping with hot regeneration gas regenerates it. Condensing the stream when leaving the regenerating adsorber separates H2O and heavy hydrocarbons.
In a typical natural gas plant two, three or four adsorbers are applied to allow for online regeneration. As the process relies on selective adsorption of heavy hydrocarbons and H2O, the attainable dew point specification is virtually independent of the natural gas pressure. This is a major advantage over low temperature separation technology when natural gas is available at a relatively low-pressure (
