MDEA configuration

This post was last edited by adsl121 on 2010-3-31 00:49 to ask you a question.: How is the MDEA lean solution prepared in your organization? Is the solution preparation tank used in the process of preparing the amine solution? actively participate
The preparation tank has never been prepared. It is added directly to the solvent storage tank and then added with water.
First add the MDEA solvent to the solvent preparation tank, then add water to prepare it, and then pump it to the solvent storage tank!
Because the amine liquid preparation tank is small in size, it is impossible to prepare the required amount of amine liquid. Therefore, it is first prepared in the amine liquid preparation tank and then pumped to the amine liquid storage tank by machine, and then continues to be prepared and sent to the amine liquid storage tank until a sufficient amount is prepared. The amine liquid storage tank plays a storage role, but it cannot be configured directly in it because it needs to be stirred evenly, etc.
Pour fresh MDEA into the preparation tank, then use air pressure to the system's lean liquid tank, and add some desalted water to the lean liquid tank.
What everyone above said is not very detailed. Is there anything specific? The first configuration method: Put the amine liquid into the amine liquid storage tank (what is used to send the liquid out), add water, and dilute it to the required concentration (what water is added and why it is used). After the configuration is completed, is the amine liquid tank sealed? Medium used? The second configuration method: Put the amine liquid into the solvent preparation tank (how is it added? What is the waste amine liquid inside the preparation tank during normal production), and add water (same as above). actively participate

1. Inject desalted water into the solvent storage tank. The liquid level is about 60%. Calculate the approximate tonnage. 2. Add the calculated amount of pure amine liquid into the solvent preparation tank (calculated based on the required amine concentration). 3. Transfer the amine liquid from the solvent preparation tank to the solvent storage tank by using nitrogen to pressurize it several times or start the solvent preparation pump. 4. Start the lean liquid pump to circulate the solvent in the solvent storage tank, and then take samples to analyze the concentration.
4# In light summer wind, we use demineralized water here. You can also use deoxygenated water. The effect of deoxygenated water should be good and the configuration speed is fast.
Our workshop configures the amine liquid as follows: 1. Introduce the required pure amine liquid into the preparation tank 2. Add the required amount of desalted water 3. Turn on the pump to circulate 4. Contact the laboratory for sampling and check the concentration

As for the concentration of amine liquid, the general design requirement is about 20%-30%. You have to decide the specific concentration according to the specific operating environment of your device.
