Operation of the amine solution regeneration tower

The temperature of the lean liquid should be between 35-42°C, right?
You need to take into account the type and concentration of the alcohol amine solution you are using. Most of these solutions are of the composite type, with concentrations typically ranging from 20% to 30%. The temperature of the liquefied gas feed generally does not exceed 40 degrees, and the dry gas in the gas tanks is equipped with coolers; temperatures between 30-40 degrees represent normal operating conditions. When controlling the temperature after cooling in the reactor tower, attention should be paid to the pressure in the tower; when using an amine solution with a concentration of 20%, the temperature should not be too low, as this will result in more acidic water being produced
We generally keep the temperature at the bottom of the regeneration tower at 130°C, and the temperature after cooling at the top of the tower between 40–50°C; the results are quite satisfactory!
Reactor bottom temperature: 125; top temperature: controlled at 45–60
The temperature after cooling should be around 45–60, and the maximum temperature should be around 110
Yes, the top temperature is 105–110, and after cooling it’s 45–60
Top temperature: 108; cooling time: 45–60
