clairmonte processes: natural gas: co2 and h2s separation by ethanolamine
DESCRIPTION
Removal of CO2 and H2S from natural gas using ethanolamine, the process allows regeneration of ethanolamine. Diethanolamine, Methyl MonoEthanolamine, DiGlycolAmine can also be used.TRANSCRIPT
NATURAL GAS: CO2 AND H2S SEPARATION BY ETHANOLAMINE
The use of the family of amino alcohols like MonoEthanolAmine to separate CO2 and H2S
from natural gas is the most popular industrial choice, as it is practically simple, and has the
capacity to separate both CO2 and H2S at the same time, and Ethanolamine can be regenerated.
Processes like SULFATREAT, and PURASPEC, ZnO over Co/Mo catalyst separate only H2S
and some sulfur compounds only, leaving CO2. Also these processes impose complete
replacement of catalyst without regeneration like amino alcohols. SULFATREAT imposes
incoming feed to be saturated with water vapor.

There are several amino alcohols which are used for the removal of CO2 and H2S from
natural gas:
MEA MonoEthanolAmine DEA DiEthanolAmine MMEA MonoMethylEthanolAmine DGA DiGlycolAmine DIPA Di-isoPropanolAmine AMP 2 Amino 2 Methyl 1 Propanolamine
In absorption of CO2 and H2S gases MEA and DEA perform best, however in regeneration
MMEA and DGA perform better. Consequently a mixture of the amino alcohols is recommended.

Our professional experience allows us to avoid completely any foaming. Most of the plant is
mainly of stainless steel construction. Our workshop handles several tasks, consequently we avail
for our clients their jobs in a very short time. We also would recommend the appropriate choice
which type of amino alcohols to be used.
