Amine Concentration in Gas Sweetening Plant

[ChemEngSquirrel]

My gas sweetening plant was designed to run with 50% wt amine solution. I'd like to increase concentration to 70% wt amine (the reason for this change is not important for this query).

Other than higher frictional losses due to higher viscosity, are there are other issues with operating my plant with a higher amine wt % that i should consider?

Thanks.

when you increase amine concentration, you face with enhancement in corrosion and energy consumption.
