How to configure the concentration of lean liquid and how much should be added
The concentration of amine liquid is usually around 35%.
To prepare lean amine liquid, deoxygenated water is generally used, and desalted water is also used. However, desalted water contains oxygen, which affects the quality of the amine liquid.； It is best not to use fresh water. The preparation concentration is based on the design requirements, generally 30-35% (w), and some can reach 40% (w). The concentration is high and the absorption effect is good. It can reduce the circulation volume and save energy, but it is easy to foam.

This requires estimating a system storage capacity, such as 200 tons, and also knowing the concentration of fresh amine liquid, such as 95%. Assuming that 35% of amine liquid is to be configured, it is 200* 0.35/0.95=74 tons of ethanolamine, plus 126 tons of water. But the final concentration still depends on laboratory analysis.
How do you calculate adding 126 tons of water? Teacher
