Gas Treatment Chemicals

It is not only waters that get contaminated naturally and unintentionally, but gas also. Contaminated gases can give potential harm not just to the people but equipment and the environment.

Natural gas must be treated because H2S and CO2 can be corrosive to equipment, tanks, and pipelines. Diethanolamine (DEA) and Methyl diethanolamine (MDEA) are used in the treatment method to remove H2S and CO2 from natural gas before it’s fit for use in various industries (residential, fertilisers, industrial, petrochemicals, commercial, power generation). Natural gas must be treated or ‘sweetened’ because H2S and CO2 can be corrosive to equipment, tanks, and pipelines.

WHAT CAN YOU EXPECT FROM IT?

And with the aid of some chemicals that can help improve the quality of gases and somehow prevent it from being contaminated, our gas resources might be taken into consideration that it will be preserved and well-managed.

That is why National Energy and Engineering offers two of the most used gas treatment chemicals: Methyl Diethanolamine (MDEA) and Diethanolamine (DEA). Both are used in the treatment method to remove H2S and CO2 from natural gas before its fit for use in various industries.

CHALLENGES

• High solvent cost and low comparative reactivity of MDEA

• May encounter non-selective removal in a mixed acid gas system

• High heat reaction in the carbon dioxide

• The degradation products of DEA can be corrosive

• DEA may not be reclaimable at most units, and it decomposes below boiling point at atmospheric pressure

BENEFITS

• Removal of hydrogen sulfide and carbon dioxide from sour gas

• Both are effective sweetening of the acid gas

• Safer equipment that is far from being destroyed due to corrosion by the toxics in the natural gas.
