Seeking help regarding unqualified MDEA desulfurization products
Thread Content
The system currently in operation uses MDEA for desulfurization and partial decarburization. The current operating conditions are not satisfactory; mainly, the hydrogen sulfide content in the purified gas at the outlet exceeds the specified limits, and there are significant fluctuations. Let’s discuss what factors affect MDEA’s ability to absorb hydrogen sulfide. Specific data is needed; for more information, please contact QQ22975379. I hope that with the help of this forum, we can overcome the difficulties in production. Thank you all in advance.
Quality of regenerated amine solution, amine solution circulation rate. The tray section of the absorption tower is partially blocked, and the tray section of the regeneration tower is also partially blocked. Amine solution foaming. Internal leakage in the rich-poor amine liquid heat exchanger.
For the quality of amine solution, which indicators are mainly tested? Without considering energy consumption, what are the considerations regarding the size of the circulation volume? The tower is relatively clean with no scaling. Analytical methods for MDEA: how to detect the content of inorganic ammonia in MDEA. The heat exchanger has been thoroughly inspected and repaired.
