Industrial 68% sulfuric acid is placed in a container; by heating the container directly, can we obtain a concentration of 98%?

Haven’t heard of it before; let’s see if you can develop this technology: lol

Sulfuric acid can be distilled directly; when heated, it decomposes into SO3. Even if a portion of it decomposes and the amount of sulfuric acid decreases, it is still possible to obtain 98% pure sulfuric acid through distillation. The advantage of reducing pressure is that it prevents the sulfuric acid from decomposing, thereby increasing the yield – there’s just a difference in terms of yield

Nowadays, there is a strong emphasis on environmental protection; Liaoyang Dongling Chemical Equipment Factory is involved in the production, installation, commissioning, and technical services of complete sets of equipment for sulfuric acid concentration and regeneration, nitric acid concentration and regeneration, waste acid treatment, waste acid recovery, and waste acid disposal； Complete sets of equipment and spare parts for high-silicon cast iron nitric acid concentration towers, bleaching towers, condensation towers, and acid sealing systems ； Complete set of equipment and spare parts for the concentration treatment of waste dilute sulfuric acid in kettle type systems ； We produce flange spare parts for use in factories; if you have any technical questions or need to place orders for spare parts, we will be happy to assist you patiently

This method yields a sulfuric acid concentration of up to 98.3%.

Let’s take a look at the industrialization approach – how can the issue of material corrosion be addressed? Wait

It is easy to concentrate it to 50%, but concentrating it to 98% is costly and requires significant investment

No. I’ve never heard of such a method
