How to address wastewater in acrylic acid production
Thread Content
The current mainstream production processes in China generate large amounts of wastewater during manufacturing. Manufacturers resort to various methods, including subsequent water treatment solutions, to address this issue. Although pollution is to some extent controlled, these methods are still costly and require significant investment. With the implementation of **the latest emission standards, wastewater treatment can no longer meet** these new standards. So, is it inevitable to generate wastewater in acrylic acid production? Are there any better processes that can avoid the production of wastewater? Commissioned by an acrylic company, our company’s technical staff spent 2 months working on this challenge, and have now succeeded in overcoming it. By replacing the azeotrope, we redesigned a process scheme that makes maximum use of the existing equipment. This solution generates no wastewater, resulting in zero emissions, and its production cost has been reduced by 500 yuan per ton compared to before.
The domestic market needs such companies with specialized expertise to conduct research in this area. It’s a pity there are so few.

It involves applying the MIBK process to toluene processing units, with possibly using cyclohexane, which is immiscible with water, as an azeotrope
It’s not MIBK; using MIBK presents many problems – it isn’t the best azeotrope, so we use another one instead.
It’s not the cyclohexane you mentioned; the azeotrope component is currently kept confidential and cannot be disclosed.
This is how **environmental regulations drive technological advancements, thereby promoting social progress. Without pressure, there is no motivation.
