Process Description

The application of Uhde's Morphysorb^® process for a bulk sour gas removal unit is described below as an example.

The feed gas enters the bottom of the absorber, flows upward through a packed bed, where it is treated with the regenerated Morphysorb^® solvent, and leaves the absorber at the top.

The enriched solvent exits the absorber at the bottom and is flashed consecutively into the recycle flash drums. The off-gas from these drums is recycled to the absorber feed by a two-stage compressor in order to minimise methane losses.

The solvent is further flashed into the acid gas flash drums for regeneration. The acid gas is produced at two pressure levels for further processing in a Claus plant or for high-pressure downhole re-injection. The regenerated Morphysorb^® solvent is pumped back to the absorber.

The Morphysorb® solvent is also suitable for spec removal of H2S and CO2 from sour gas streams.
