The problem of scaling in waste acid concentration heat exchangers
Thread Content
According to information found online, during the process of concentrating waste acid, scaling in heat exchangers is a common problem across the industry, one that has remained difficult to solve over the years. Coincidentally, our company’s new technology – microwave scale inhibition and removal technology – offers excellent effects in preventing scaling caused by various types of substances such as carbonates, phosphates, sulfates, oxalates, silicates, and metal oxide scales. It has been successfully applied in preventing scaling in alumina solutions, rare earth solutions, sulfuric acid solutions, and lithium carbonate solutions. I believe our technology can address the problem of heat exchanger scaling in the waste acid concentration process, so we plan to promote it in this industry in order to solve this technical challenge related to scaling in heat exchangers. So, those with experience in acid concentration are welcome to come and offer some guidance? Thank you so much! If you’re interested in learning more, feel free to message me privately or leave a comment below.
Yes, the microwave scale inhibition and removal technology seems very promising. It’s a good solution to the problem of heat exchanger scaling in the waste acid concentration process. I hope experienced people can provide more guidance and advice. It would be better if specific technical parameters or experimental data could be shared, to help everyone understand better the effectiveness and scope of application of this technology. .
Is there a product description, or what are the limitations?

OP, the first issue that needs to be addressed is whether microwave energy can propagate in water (waste acid) What is the efficiency of conduction in graphite? Additionally, microwaves are high-frequency electromagnetic waves; is there any radiation from them to the human body? All of these need to be taken into consideration. Three years ago, we considered using ultrasonic methods to prevent scale formation; we sent graphite blocks with scale attached for testing, but the \"cavitation\" effect was not satisfactory. The heaters used for concentrating waste acid are often made of graphite; ultrasonic waves are not transmitted efficiently through them, and they are also unsuitable for transporting concentrated acid. If you’re confident, please reply. Let’s talk more
1. Signal transmission is indeed a problem; ultrasonic waves are expected to travel only a short distance in waste acid. However, we have resolved this issue, and the effective operating distance within the material or waste acid is estimated to be 40–50 meters. 2. It can conduct electricity properly in graphite. 3. The signals tend to converge inward; there are few signals that spread outward, so the radiation is very low.
I’ve written a paper on what depends on microwaves. In fact, looking at it now, if one approaches things in a straightforward technical manner, no effective solutions have been found yet – aside from empty promises and the creation of conceptual ideas
Are there any other processes for concentrating waste acid? Fellow sailors can come and discuss this.
