I have designed, built, and operated my own MEA reclaimers in the field. I have always recommended the proper use of reclaimers on amine solutions - specifically MEA. I’ve operated these units in 20% wt. solutions as well as on 12-15% wt. solutions with a lot of success. The success was related to the absence of corrosion and the control of the MEA solution quality and consumption. I can upload some literature on the subject that I’ve transcribed to electronic files recently (and continue to do) that may help you answer your questions. This information comes from gas conditioning experts who designed and operated MEA reclaimers in the past. In my youth, I actively attended a lot of conferences on the subject since in my time this was a “black art” and little known. Even the classical gas purification text books like Kohl & Risenfeld, Kohl & Nielsen, etc., don’t go into the design and operating details needed. This is probably because they’ve never built or operated one.
I’ve always advocated that the best and most successful way to operate an MEA acid gas removal unit is to keep the solution as clean, pure, and low in concentration as you can afford. I have operated mostly with 15% wt. MEA solutions as a max., without a so-called “reflux” on the stripper, with a constant 2-3% of solution flow reclaimed, full flow activated carbon filters, and a water scrubber on the MEA contactor gas product line. These efforts resulted in record low MEA consumption, no corrosion, and constant process production with no upsets.
I can’t address your specific question on whether you “need” a reclaimer or not without studying the application through a detailed P&ID and basic design information. But I can explain how to design and operate one or the details on what you should consider before applying one in a gas conditioning unit.
I also have a question: are you located in Russia - or perhaps Denmark?
